2021 Nebraska Cover Crop and Soil Health Conference - Panel Discussion
Speaker Panel Q/A
Toggle between list and paragraph view.
- [00:00:16.070]There were, quite a number of,
- [00:00:19.880]quite a number of questions that,
that came in for, for Ken. And I,
- [00:00:24.270]I think so moving, moving right
into the, moving right into the,
- [00:00:29.180]the panel discussion, I'll,
I'll read those questions can,
- [00:00:33.710]and you can answer those,
as best you can.
- [00:00:38.720]there are
- [00:00:44.180]I do know who submitted some of the
questions this first one's from Fich
- [00:00:47.510]Russell. I know Rich, Rich,
thanks for joining today.
- [00:00:51.320]Ken, Rich asks, how does the six year,
- [00:00:54.830]or does the six year revenue
include the value of grazing
- [00:00:59.990]from gained AUMs or so,
so basically did the,
- [00:01:04.940]grazing value include any
additional animal weight gain?
- [00:01:10.190]No, it never,
- [00:01:11.150]we just put a value on the AUM now,
- [00:01:16.130]because that would, Oh, well,
- [00:01:20.150]we're trying to keep things as
simple as possible. you know,
- [00:01:24.440]you can say, even in our range land,
- [00:01:28.400]grazing day cost me so much out there.
- [00:01:31.580]but I make money at that somehow.
- [00:01:34.070]And so we just put a value for the grazing
- [00:01:38.720]on there just to keep things,
- [00:01:41.720]pretty simple on and not to complicate,
what was trying to look at.
- [00:01:48.500]Yeah. But then there's a, a, there's
an I'll skip to the simple one first,
- [00:01:52.730]and then I'll go to the complicated one.
there was a question on the,
- [00:01:57.140]the cover crops that were grazed
for corn. the question is, is,
- [00:02:01.630]is no till used or did
you disk in the residue?
- [00:02:05.900]I would assume after grazing.
- [00:02:08.000]we have been no tilling
since about 1990.
- [00:02:12.410]so everything is no tilled.
- [00:02:15.020]Okay. And then here's
another question on the,
- [00:02:20.120]on the, dollar comparisons.
And again, I'm going to read the,
- [00:02:24.470]read the question and not try
to interpret it in a yet.
- [00:02:28.010]does the value of animal
unit months graze added
- [00:02:32.900]value to the graves cover crop treatment,
- [00:02:38.600]reference at an alternative feed value
for the cattle was subtracted from
- [00:02:43.520]the scenarios that did not allow grazing.
- [00:02:47.720]if I understand the
question is that,
- [00:02:53.750]are we comparing the value of the
cover crop raising to the value of a
- [00:02:58.620]purchase feed? Is, is, is
that just that, the question.
- [00:03:04.110]That, that that's, that's the
way I understand that. Yes.
- [00:03:06.810]Okay. No, we didn't make
any comparisons to that. We,
- [00:03:11.070]we just use, try to use a generic,
- [00:03:15.360]value of grazing what it costs in
our area for animal unit months
- [00:03:20.580]and assign that value to the
cover crop. of again,
- [00:03:25.440]of course,
- [00:03:26.850]we expect to make a money,
- [00:03:30.820]a profit center on the cattle,
based upon those,
- [00:03:35.460]greasing costs.
- [00:03:38.220]Okay, thank you. You know, and I mean,
and for everybody that that's out there,
- [00:03:42.510]this, integrated systems work is,
- [00:03:46.860]is pretty darn hard and difficult to
do. It's, it's very time consuming.
- [00:03:51.420]There's a lot of overlap and a lot
of the management practices that are,
- [00:03:56.580]are critical. And I know can just,
- [00:03:59.130]when you think you've got things figured
out the weather doesn't cooperate with
- [00:04:03.780]you either, you know, and, and so I,
I know there's been some, you know,
- [00:04:07.950]Benson challenges, you know, no fault
of anybody's other than the weather.
- [00:04:12.450]So, you know, I,
- [00:04:13.900]I certainly appreciate the time that
you've devoted to helping us collect a
- [00:04:18.720]lot of this information that
otherwise we wouldn't be able,
- [00:04:23.010]wouldn't be able to gather.
- [00:04:24.870]Yeah. And Darren, I skipped over
a slide, I'm sorry about that. But it,
- [00:04:29.730]it, the slide was about,
- [00:04:34.140]And we were looking at,
bacteria and the fungi in there.
- [00:04:38.940]And, I don't know how
I skipped over it, but I did,
- [00:04:43.080]but in that, in the cover crop,
that was grace. It had a much,
- [00:04:47.730]much higher activity of
bacteria and fungi in there
- [00:04:52.470]than even what the cover
crop that was on grace.
- [00:04:55.290]So there's something about the
livestock that really adds value to that
- [00:05:00.000]cover crop, what
what's happening out there.
- [00:05:04.620]Well, you know, and that's, that's
a good point because I, I, you know,
- [00:05:07.260]where we're seeing some of that
in some other research as well,
- [00:05:10.590]we haven't really gotten a
good handle on exactly the,
- [00:05:14.460]what's the cause and effect of that,
- [00:05:16.470]but that is a pretty common response
to that. We're starting to,
- [00:05:21.630]starting to see, there was
a, another question, for,
- [00:05:26.400]can you're off the hook
for the time being, no, wait,
- [00:05:30.770]you didn't one more question.
did you encounter any problems,
- [00:05:35.580]when you were planting, the,
- [00:05:39.030]the subsequent crop after
the cover crops,
- [00:05:42.900]that the cattle had caused any,
- [00:05:44.880]a disturbance or saw compaction
of the, of the sole surface?
- [00:05:50.070]Are there any planning difficulties of
the subsequent crop after grazing the
- [00:05:55.620]no, there wasn't.
and that was part of the,
- [00:06:00.490]soil health that we did
too. We, we, we took,
- [00:06:03.640]I don't even remember the names of
it, but we took,
- [00:06:08.390]tests on the compaction of
the soil. And there is no,
- [00:06:11.540]no difference in any of
the soils. So, no,
- [00:06:14.750]there was no problems planning into
there after the cattle grazed on there.
- [00:06:20.200]Okay, perfect. Thank you
very much. Jerry,
- [00:06:24.580]there were a couple of questions
for you that were along a similar,
- [00:06:30.010]similar thought process,
and it was about the,
- [00:06:33.730]the hybrid genetic
affects on the yields,
- [00:06:37.960]for the two studies you referenced,
and in particular, the,
- [00:06:41.890]the one from, 2003,
- [00:06:45.760]to 2018, the example
that was provided was,
- [00:06:53.050]Yeah, I mean that, that part of that,
- [00:06:56.290]and I did answer that back in
the, in the chat box as well,
- [00:07:00.070]but I'll answer it here. I mean,
when we start looking at,
- [00:07:03.310]anytime you deal across
length of record,
- [00:07:06.580]we have a changing set of hybrids.
All of this, what we saw,
- [00:07:11.320]was that there were multiple hybrids
run across those fields. you know,
- [00:07:18.130]we, I don't, I think we
only had ACO max,
- [00:07:21.850]one of the years and
that really wasn't much
- [00:07:27.250]of an effect. What we really see is
that, that, that slope of that line,
- [00:07:32.020]as we begin to change the soil and then
improving that Seoul variation,
- [00:07:37.060]is irrespective of hybrid
that's out there. And so
- [00:07:41.890]we, I mean, we look across other
fields and we're not seeing a, a,
- [00:07:46.580]a diminishing of the spatial
variation within fields,
- [00:07:51.280]over time.
- [00:07:51.940]And so it really is that change in
that soil health that's causing that,
- [00:07:56.920]that variation to
change. And so, you know,
- [00:07:59.910]we can begin to look at it
from that perspective as well.
- [00:08:02.560]Plus the slope of that yield increases
is much different than the County
- [00:08:07.390]average, and you expect the suite of
hybrids across the County as well. So,
- [00:08:12.190]but it's an excellent question because it,
- [00:08:14.410]it really does pause you to think
about, you know, what are we doing?
- [00:08:18.010]And there's all sorts of tweaks that
we find when we do them. You know,
- [00:08:21.220]Ken can always talk about the,
- [00:08:22.990]the tweaks that he makes in
his operation for year to year.
- [00:08:25.750]We see the same thing in other
field studies, and we, you know,
- [00:08:29.350]we really have to look at it and that's
why we took it against the County
- [00:08:32.140]average, for a dynamic.
- [00:08:34.660]Okay. Yeah. Thanks. And I, I,
you know, I mean, it's, it's,
- [00:08:38.380]there nearly all of the speakers today
have been in the chat answering many of
- [00:08:42.610]those questions. And so, most
of you get, you guys went early,
- [00:08:46.840]I'm going to ask you to provide a brief
summary of, of some of the questions.
- [00:08:50.590]So, Jerry, thanks for, thanks
for talking about that response,
- [00:08:54.550]because I don't think anybody's
- [00:08:58.320]got enough hands and eyes to keep up
with all the moving pieces of this in
- [00:09:02.700]particular with all the,
the questions that the,
- [00:09:06.990]that are coming today, you know, so
that's, we never know what to expect,
- [00:09:10.950]but you know, questions for the
speakers are, are certainly good.
- [00:09:15.270]there was another question
on, on measuring,
- [00:09:18.120]carbon sequestration on an
annual basis versus thinking more
- [00:09:22.740]long-term can you address that, Jerry?
- [00:09:25.940]Yeah. I mean, you, that's, that's
probably the question of the day.
- [00:09:30.290]that's been the question of the
last week when we're moving more into a
- [00:09:35.750]carbon markets and everything, and, and I,
- [00:09:39.280]and Kristen might have some
opinions about this as well,
- [00:09:42.530]because she's been looking
at techniques, but, you know,
- [00:09:45.140]when we start looking
at soil organic matter,
- [00:09:47.270]it is difficult to look at that change
on a yearly basis. But I think that part,
- [00:09:51.980]what we see is that we do see,
- [00:09:55.760]changes in,
particular organic matter.
- [00:10:00.290]we see other parts of it in terms
of looking at the aggregate systems.
- [00:10:05.180]I think we're going to have to look
at different measurements of how we're
- [00:10:08.840]putting carbon into that soil. Do we look
at biomass, look at microbial biomass.
- [00:10:13.670]We know that there's been
an impact on CO2,
- [00:10:17.480]which is reflective of adding
biomass into that soil.
- [00:10:21.740]so I think in, in next year,
- [00:10:25.640]we're going to have a lot of different
ways in which we look at our soil.
- [00:10:29.210]I think the soil health indices
are kind of moving us towards,
- [00:10:33.740]being able to look at different pieces
of this, but there always be a debate,
- [00:10:39.170]about, you know, how much
carbon we've really stored in that soil.
- [00:10:44.240]And I think we're going to have to come
up with some really good answers on this
- [00:10:48.110]for the whole carbon markets that,
that want to re-emerge. Right.
- [00:10:52.550]Yeah. Kristen, do you have
anything to add to that?
- [00:10:56.870]Well, I think he summed
it up very well. You know,
- [00:10:59.600]measuring solid carbon really is
the gold standard for what's in
- [00:11:04.400]that, in that pool. So how
much slow carbon do we have?
- [00:11:08.660]And when it,
- [00:11:10.790]when it comes to understanding those
long-term impacts of agriculture,
- [00:11:16.100]I'll just make a plug for long-term
research and I can apply those
- [00:11:20.600]results. Every site, everywhere,
- [00:11:24.560]some of these changes happened
pretty slowly and are hard to detect.
- [00:11:29.150]And so, you know,
- [00:11:30.050]we have to look to those long-term studies
to give us some general information.
- [00:11:35.540]And then when it comes to specific sites,
- [00:11:38.000]there's some level of inference
that you have to make there.
- [00:11:40.550]And it's not as easy as
we'd like it to be, I guess.
- [00:11:46.040]Yeah, no, that that's exactly true.
Andrew, do you have any comments,
- [00:11:50.210]on that topic?
- [00:11:55.470]The only thing that I might add,
- [00:11:58.140]Kristen and Jerry are probably much
more familiar than I am. I mean,
- [00:12:01.080]I'm interested in some of the things
we're looking at in our project include
- [00:12:04.890]some of the more lay bile or more
rapidly turning over pools of carbon.
- [00:12:09.720]That could be, you know, not
necessarily long-term sea quotation,
- [00:12:13.830]but some indicator of
increasing soil carbon from,
- [00:12:18.960]things like cover crops.
So I think that, yeah,
- [00:12:21.360]there maybe some other
indicators and just whole
- [00:12:25.890]profile soil carbon
that could be, you know,
- [00:12:28.680]giving us some indicator of what's
happening in those pools. So,
- [00:12:34.710]Darren had,
- [00:12:35.790]I just like to add a little bit of
that is when we come back to,
- [00:12:40.470]our Eddy flux measurements,
- [00:12:41.910]because we did take a field
and we converted it from a
- [00:12:46.560]conventional till system to a
no till cover crop and with the,
- [00:12:51.480]Eddy correlation systems,
- [00:12:53.250]we could see an increase in
carbon storage somewhere around
- [00:12:57.900]500 pounds.
- [00:12:59.670]Now you'd have a hard time finding
500 pounds of carbon and when we start
- [00:13:04.440]making soil measurements, but when we
see that with the flux measurements,
- [00:13:08.310]you know, it's,
- [00:13:08.720]it's pretty indicative that we are
making a positive change in terms of the
- [00:13:12.450]dynamics that are going on.
- [00:13:13.920]So I think we're going to have
to look at maybe combinations of,
- [00:13:17.090]of different things that we get
there. And as Andrew pointed out,
- [00:13:20.790]a lot of this are very
fast moving pools.
- [00:13:24.090]microbial systems are extremely
flexible and they're extremely
- [00:13:28.890]dynamic. And so I think that there's,
- [00:13:31.830]there's a lot of opportunity to
figure out what what's going on. So.
- [00:13:37.500]No, yeah, thanks for thanks.
That was a good discussion.
- [00:13:40.080]One of the things I neglected to do is,
- [00:13:42.150]is give instructions
to our satellite sites.
- [00:13:45.900]You seven guys that are scattered
out across the state that have a,
- [00:13:50.580]population of,
attendees at this meeting as well.
- [00:13:55.140]If you guys have any questions, I think
the best thing to do might be to,
- [00:14:01.080]use that little, raise your hand
icon, and then I'll call on you.
- [00:14:05.460]And you can ask that question.
- [00:14:10.890]Kristen, could you answer
a few questions after your,
- [00:14:15.810]after your presentation,
that were in the chat?
- [00:14:19.380]Can you give a very brief summary on,
- [00:14:23.280]how you responded to a question or two?
- [00:14:26.370]Yeah. Well, one,
- [00:14:27.060]one question was about
the costs of these infield
- [00:14:31.750]spectroscopy methods and
what that would look like if,
- [00:14:36.090]if somebody were to try to pay
for them to see the service basis.
- [00:14:40.740]you know, right now there,
- [00:14:42.390]I know there are some vendors out
there who offer this service.
- [00:14:46.740]it's usually targeting organic matter
and there are some other similar
- [00:14:51.380]properties that perhaps
are available, from,
- [00:14:56.030]from needs that commercial operations.
But when it comes to total costs,
- [00:15:00.770]you know, the, the machinery,
- [00:15:03.230]the equipment is really expensive upfront.
- [00:15:06.950]And then if you're a researcher or
someone who own it and you take it out,
- [00:15:12.050]there may be costs associated with
travel. So if there's not one nearby,
- [00:15:16.700]you know, who's gonna bring
it out. Who's been operated,
- [00:15:19.580]who's going to get the
data and process it.
- [00:15:21.980]So currently I think those costs are
probably higher than they would be,
- [00:15:27.350]you know, way down the road when we
get better at doing this. And my,
- [00:15:32.110]my thought is that right now, you know,
- [00:15:34.070]there's still a lot of
room for improvement,
- [00:15:35.930]especially when we look at the other
soil properties that we're interested in.
- [00:15:39.560]So there's total carbon, but that's not,
- [00:15:42.740]that's not the be all and
end all and soil health,
- [00:15:45.150]although it's really important.
So, you know, currently right now,
- [00:15:49.310]I guess I don't have an answer for what
the cost would be for someone to do like
- [00:15:53.600]a full soil health assessment. Cause
I don't think that's really available.
- [00:15:58.700]And the only other question
I had was about,
- [00:16:01.490]the university of Missouri has this
little health assessment center.
- [00:16:05.090]It's in the same city where I'm located,
- [00:16:06.950]but it's a different lab and
they offer a lot of soil health
- [00:16:11.690]tests, on a service basis, but not.
- [00:16:18.250]Perfect. Thank you,
Andrea. You had a question,
- [00:16:22.240]I don't think you responded to you. You
could have, and if you did, I apologize,
- [00:16:27.220]but there was a, a
question on, on any,
- [00:16:30.970]research responses that are related
to, crop nutrient levels,
- [00:16:36.370]as they affect human health.
- [00:16:40.900]Do you have any comments or,
or knowledge along those lines?
- [00:16:44.920]Kristen may have some idea about
that as well, or, or Jerry might.
- [00:16:50.380]Yeah. I mean, I'd like
the, the answer is,
- [00:16:52.910]I feel like it's an emerging field and
a topic that there's a lot of interest
- [00:16:56.560]in. And to be honest, like I think
those links are hard to draw.
- [00:17:01.360]Like I just think like all of
epidemiology and human health is hard to
- [00:17:06.490]create those links, but,
- [00:17:08.140]so I'm not really as familiar
as I probably could or
should be on some of these
- [00:17:11.560]things. I know that there's a lot of
interest in demonstrating it. I might,
- [00:17:16.060]and I appreciate it.
I would just add that.
- [00:17:17.620]I appreciate the spirit of that
question because I do think, you know,
- [00:17:20.650]and for all, you know, two to 300
people who joined this meeting,
- [00:17:24.340]I think we can all see the need
for metrics beyond yield and
- [00:17:29.230]thinking about quality and
human health are all good ones.
- [00:17:33.310]So I appreciate the
spirit of that question.
- [00:17:34.960]I think that it's a sort
of new and emerging area.
- [00:17:37.700]So I don't know Jerry or Kristen might
have more to add and more familiarity.
- [00:17:44.050]It's become a really.
- [00:17:46.700]As Andrea pointed out. I mean,
it's become a hot topic right.
- [00:17:50.070]Now in terms of what's the
linkage between soil health,
- [00:17:54.660]human health,
- [00:17:56.100]particularly from the standpoint
of nutrient density of crops.
- [00:18:00.240]We know that there's some
effect out there, but you know,
- [00:18:04.020]you get back a lot of this, that,
- [00:18:05.880]that nutrient dynamics
and concentration in
- [00:18:10.800]grain, there's a major weather
component and, and that as well,
- [00:18:15.660]I mean, it's just use protein
is an example. if you
want high protein crops,
- [00:18:20.520]just have a drought, you
know, it doesn't get you yield,
- [00:18:24.360]but it gets you high
protein. you know,
- [00:18:26.670]and so I think that we're going
to have to deep unravel some
- [00:18:31.590]of these linkages, in
terms of these dynamics. And,
- [00:18:36.180]and one of the things that we do see in
there going back to the why soil health
- [00:18:40.290]is so important during the, the
latter part of the growing season,
- [00:18:43.680]because if we can increase that,
- [00:18:47.230]that photosynthetic canopy and that
duration that's when we see a lot of
- [00:18:52.170]the quality products
really go into the green.
- [00:18:55.380]And so I think there's some aspects of
that, that we need to discover as well.
- [00:18:59.910]But it's, it's not a
simple process. I mean,
- [00:19:02.760]there's been a lot of discussion
lately with several of us around the
- [00:19:07.320]globe thinking about
this and it, you know, I,
- [00:19:11.630]I only need to work another 40 or 50
years probably to figure that one.
- [00:19:20.420]Thanks, Chad,
- [00:19:22.410]are you still hanging
with us bill here? Hey,
- [00:19:26.870]so I know we, you were,
- [00:19:28.500]we're pretty early in the process today
and you had quite a number of questions,
- [00:19:33.380]that you responded to during
the early part of the conference.
- [00:19:36.950]Could you give us a brief summary
of a few of those questions that you
- [00:19:41.660]responded to, in particular,
if there were any that overlapped?
- [00:19:47.930]there was a one that I
found fairly interesting
- [00:19:52.850]and it had been brought up
to me before in the past.
- [00:19:57.290]but the question was, have I
tried planting cereal right?
- [00:20:00.980]With the direction of the
cornrows and then,
- [00:20:04.340]splitting them with the crop.
- [00:20:07.190]And my answer was that I had
thought about that before,
- [00:20:13.490]my current equipment set
up as far as GPS goes,
- [00:20:18.200]I'm just using a free signal.
- [00:20:19.550]So the accuracy of using
the GPS to split 15 intros,
- [00:20:24.170]isn't something that I feel I'm capable
of at the moment, but at the same time,
- [00:20:29.150]if I could upgrade to RTK,
- [00:20:32.510]that would allow me to
do that as well as,
- [00:20:35.540]I'd have to have a little
- [00:20:39.290]or some more instructions for the
operator of the cover crop planner in the
- [00:20:43.790]fall. Cause it would essentially
be, I would have to lay it,
- [00:20:47.920]lay the field out as I would be wanting
to plan it the following spring.
- [00:20:52.240]So there'd be some additional
management there and,
- [00:20:56.530]getting things laid out properly,
- [00:20:58.330]but that is something that
would be a good concept to
- [00:21:03.130]avoid, planting any crop
over top of that. Right.
- [00:21:08.560]And as well as, when strip
tilling, I wouldn't have to,
- [00:21:12.130]I wouldn't eliminate some of the stand
running the strip till bar through there.
- [00:21:15.730]So that was something I
found as interesting with a
- [00:21:20.710]question. another one was,
- [00:21:25.030]as far as terminating of the cover crops,
- [00:21:27.970]I know I probably
bounced around a lot,
- [00:21:31.480]with what I do versus, some management
tips and factors and stuff like that.
- [00:21:36.070]But, one was as far as
terminating the cover crop,
- [00:21:41.620]after planting corn, is this
done 24 to 48 hours after planting?
- [00:21:45.700]Or do I wait until the corn crop has
emerged and how late have I gone,
- [00:21:50.650]with termination after planning?
- [00:21:55.180]so as far as the termination,
after corn planting,
- [00:21:58.950]I don't really have a set,
- [00:22:01.870]timeframe is as long as it's before
corn emergence is really what I'm
- [00:22:06.730]after. and ideally,
- [00:22:11.290]it would be just a date within a
day or two following the planner.
- [00:22:14.920]Obviously spring time,
- [00:22:16.630]it can take several weeks even depending
on the weather for the corn to emerge.
- [00:22:21.070]And so I typically have a,
a good amount of time,
- [00:22:25.660]but at the same time,
- [00:22:26.410]if it's taken two to three weeks
or three weeks or more to emerge,
- [00:22:29.920]usually there's weather
issues causing that.
- [00:22:32.740]So typically try to follow the
planner as close as possible.
- [00:22:38.320]So maybe I mentioned
that, I try to do it.
- [00:22:44.740]I tried to do it after plan. I
do it after planning, but,
- [00:22:48.880]I think I've mentioned,
- [00:22:49.690]I asked or answered the question
in the chat box that soybeans I'm
- [00:22:54.700]been waiting till,
- [00:22:57.280]V2 to B3 here in the last couple
of years to terminate the rye,
- [00:23:01.660]but that is against a
cover or a crop insurance
- [00:23:06.430]rules. So, not right,
but that's the way I do it.
- [00:23:11.610]Okay. We've got a one more question
for Chad, another one for Ken,
- [00:23:16.590]and then I don't want to short,
Becca clay either.
- [00:23:20.520]and we're running shorter
discussion and man, I,
- [00:23:23.950]I hate to cut a discussion off.
- [00:23:25.770]So I think I'll bleed into our wrap
up a little bit here. so Chad,
- [00:23:30.600]Amy wanted to know his cereal rye,
your highest recommended cover crop.
- [00:23:37.110]I would say yes, for
my geography now,
- [00:23:41.370]depending on where you're at in Nebraska,
- [00:23:43.140]I'm not a hundred percent familiar
with the weather patterns out there,
- [00:23:47.540]but as far as in a corn soybean rotation,
- [00:23:51.830]I'd say cereal. Rye is probably
the number one recommendation,
- [00:23:56.420]easy to get established,
easy to terminate.
- [00:24:00.260]and it's one of the
cheapest seeds out there.
- [00:24:03.320]And it's very versatile for a
lot of different goals. Now,
- [00:24:06.890]obviously what you end up ultimately
deciding on for a cover crop
- [00:24:11.570]depends on the goal that you have
in mind, but as far as in this area,
- [00:24:15.490]cereal rise pretty well. The, the easiest
best one for that for most things,
- [00:24:22.400]it's a good place. Good
place to start.
- [00:24:26.600]Ken Paul, Hey, ask the question.
- [00:24:31.190]what changes have you made,
- [00:24:35.540]in your crop and livestock operations
from the research effort that you've been
- [00:24:40.220]working on with Jenny and Mary?
- [00:24:43.390]yeah. Thanks Paul
for the question.
- [00:24:48.880]I'd like to say,
- [00:24:50.290]this research to begin with this research
is going to continue going on for a
- [00:24:54.640]number of years longer. We are
going to change our focus,
- [00:24:59.320]instead of,
a cover crop that,
- [00:25:03.580]we're going to look more at,
sorghum cover crops,
- [00:25:08.470]and it looks like, we have
a lot better results with that.
- [00:25:12.190]So we're going to change
that, focus. we,
- [00:25:17.050]as I said, where, we
have a systems approach,
- [00:25:21.880]we really liked that in our operation.
- [00:25:24.100]We know what we're going to plant
every year. so we haven't,
- [00:25:28.690]fully made any changes yet.
- [00:25:31.720]we're still want to look at the little
bit this research, but along that nine,
- [00:25:35.830]we also, view,
- [00:25:40.450]what we do with our
range land. Because if,
- [00:25:45.730]we think it's really important
that if we can, pull those,
- [00:25:50.590]some of those livestock off of some
of that range land, late summer,
- [00:25:55.480]give it a rest at that. also
helps that range land quite a bit.
- [00:26:00.430]I know this conference is,
- [00:26:02.800]is talking about cover crops
and the benefits from it,
- [00:26:07.150]but a range land is a cover crop too,
- [00:26:10.420]and we have to take care of it
too. So we are in the process,
- [00:26:15.250]Paul of,
- [00:26:17.680]of running a shorter grazing
season, pulling cattle off,
- [00:26:22.810]late summer and,
- [00:26:25.850]utilizing some crop residues.
- [00:26:28.900]we would really like to know that,
- [00:26:32.650]this cover crop we thought
was going to work.
- [00:26:36.670]some of the things that we we are
looking at is that because of the
- [00:26:41.320]variability of the weather, because what,
- [00:26:44.100]how much cover crop you're
going to be able to grow,
- [00:26:46.620]you're going to have to
have a contingency plan.
- [00:26:49.200]And so that contingency plan is
private going to be some crop residues
- [00:26:54.120]that are bailed up that are sitting
back there that in case it doesn't rain,
- [00:26:58.470]we can use those. So, we are
making incremental changes,
- [00:27:03.480]but, we wanna get a
really firm grip on,
- [00:27:08.370]what we can expect with, going
to a cover crop behind the wheat.
- [00:27:14.420]Yeah. Can I, don't,
- [00:27:17.090]moisture's at a premium down in
your particular area for crops,
- [00:27:21.410]cover crops and orange crops.
So you have to balance a,
- [00:27:26.360]have to balance the management
on, on a lot of different avenues.
- [00:27:29.690]So thanks for that response,
- [00:27:35.030]you went through and answered
your questions too back
early in the conference.
- [00:27:39.770]could you give us a little summary on a
couple of a couple of highlights that,
- [00:27:44.240]that you responded to?
- [00:27:46.520]Sure. Thing, Darren, one of the
questions that I received was if,
- [00:27:51.950]the changes in herbicide
costs to the cover crop versus
- [00:27:56.900]non cover crop, soybean
was compared to this,
- [00:28:01.790]was stacked on the
seed and application costs.
- [00:28:04.340]And the answer to that was no, the graphs
that I shared was, was just the,
- [00:28:09.680]the changes in herbicide costs.
- [00:28:12.350]but I took a quick look and,
- [00:28:16.340]out of the,
- [00:28:18.530]219 people that had cover crops versus
non cover crop. So weaving fields,
- [00:28:23.630]15 people, after
those herbicide reductions,
- [00:28:28.550]had a cover crop, expensive,
- [00:28:32.150]less than $10 an acre.
- [00:28:34.190]And the specific program that
we're working in is $10 an acre.
- [00:28:37.280]And so with the cover crop cost share
those people would actually be a net
- [00:28:41.990]positive. but we'll also be
publishing, that later on,
- [00:28:46.850]on our website, most likely.
So keep an eye out for that.
- [00:28:50.210]another question that I had was on if,
- [00:28:55.220]people are typically charging for
custom grazing, which is when,
- [00:28:59.690]say Chad's got, cover
crops and I've got livestock,
- [00:29:04.670]and like, is, does
Chad wanna charge me,
- [00:29:09.830]to, for my livestock to
graze the cover crops?
- [00:29:12.680]And typically we didn't, most
people don't do that in Iowa,
- [00:29:17.150]at least in the cover crop
in a corn saving system,
- [00:29:20.870]just because there's not
that much growth out.
- [00:29:23.720]I did talk to one producer in,
Southeast Iowa who,
- [00:29:28.460]was charging a dollar per
head per day for grazing,
- [00:29:31.460]a summer seeded cover crop just because
there was so much more biomass out
- [00:29:35.000]there. The feed quality
was better, but, yeah,
- [00:29:39.140]so those were the two
questions that I had.
