[00:00:13.880]Hi, my name is
[00:00:14.450]Karna Dam.
[00:00:15.170]I am an extension educator with the University of Nebraska-Lincoln.
[00:00:19.790]And we're going to talk about agriculture technology.
[00:00:22.850]So what is technology generally? When I asked that question,
[00:00:27.470]the answers I get are cell phones or iPads or computers or anything
[00:00:32.420]that plugs in. Well, my question is,
[00:00:35.870]is a wood pencil technology.
[00:00:39.290]And the answer is actually yes,
[00:00:41.750]because prior to having a wood pencil,
[00:00:45.680]we would write with a feather or a quill and a bottle of ink.
[00:00:50.030]And we dip the feather in. We'd write a letter to,
[00:00:53.660]and we'd have to dip it again.
[00:00:55.610]Then someone figured out that if we take a piece of wood,
[00:00:58.940]drill a hole in it and fill it with led and sharpen it,
[00:01:02.300]we can write for extended periods of time.
[00:01:05.720]So the actual definition of technology is anything that has been
[00:01:10.190]designed or developed that helps make our world a better place,
[00:01:15.500]makes our jobs easier, more efficient and financially better.
[00:01:20.690]So let's look at what some of the technology is that happens in
[00:01:25.010]agriculture today. So years ago,
[00:01:29.270]we would have a tractor that did not have a cab on it.
[00:01:34.370]And what we ended up with in this situation were farmers with several, you know,
[00:01:38.990]with hearing problems or,
[00:01:41.990]if this tractor were to roll over,
[00:01:44.480]there was nothing to protect the farmer.
[00:01:48.080]And so through design and engineering, they developed tractor cabs.
[00:01:53.630]And initially there was just a bar that went over the top.
[00:01:57.620]It was called a rollover protection or a ROP.
[00:02:01.250]And eventually we enclosed the entire cab.
[00:02:06.440]This provides a tremendous amount of safety and comfort for our farmers.
[00:02:12.200]With this type of a cab situation, the farmers are enclosed.
[00:02:16.820]They, it,
[00:02:17.660]the sound barrier from the noise of the tractor after sitting there for eight to
[00:02:22.070]12 hours a day is not near as extensive as what it is
[00:02:26.930]on one of these. If you are out in the elements in the heat,
[00:02:31.070]in the cold in the dirt,
[00:02:32.960]this environment provides a much nicer,
[00:02:36.110]more comfortable place for you to be. And for safety,
[00:02:40.250]if this tractor were to roll over the cab is built
[00:02:45.170]strong enough that it will not collapse.
[00:02:48.110]And so therefore the farmer that's inside of the tractor is protected.
[00:02:52.970]Now,
[00:02:54.050]if we talk about what technology we have advanced to let's think
[00:02:58.960]about our cell phones and when we use our cell phones to find a
[00:03:03.310]location that we're headed to using Google maps,
[00:03:06.670]we have to figure out how does that actually work?
[00:03:10.090]It's a technology using satellites in outer space.
[00:03:13.960]And when three satellites are able to talk to each other and send a message down
[00:03:18.460]to my cell phone,
[00:03:19.870]it can identify two pretty close proximity of where it is
[00:03:24.850]I'm trying to get in agriculture today,
[00:03:29.440]we're using the same technology and this is a receiver.
[00:03:34.360]So in technology,
[00:03:36.160]these receivers sit on the cab of the tractor
[00:03:41.050]or whatever, piece of equipment that is being driven.
[00:03:45.790]So on this toy tractor, the receiver,
[00:03:48.310]which is on the roof of the cab is the receiver that is receiving the messages
[00:03:53.260]from the satellites in space.
[00:03:56.290]Those messages are then transferred into the cab of the
[00:04:01.060]tractor and this,
[00:04:04.120]this tractor has a planter behind it.
[00:04:07.360]And the planter is putting the seeds in the ground.
[00:04:11.470]Now what the farmer will see inside the tractor are two monitors.
[00:04:16.540]Similar to this.
[00:04:18.520]It will be telling him where it is he's driving.
[00:04:21.670]So this is his line that he is following through the field.
[00:04:26.500]And this map tells him how much of the field he's completed and
[00:04:31.270]how much he has yet to plant.
[00:04:34.360]This allows recordkeeping for the farmers so that they're better able to keep
[00:04:39.370]appropriate records of what they're,
[00:04:41.950]trying to do it also through GPS.
[00:04:46.930]we are able to use auto-steer so the farmers are not having to actually steer
[00:04:51.790]the tractors through the field.
[00:04:53.500]It will drive a perfectly straight line through the field. It will also,
[00:04:58.570]if the planter passes over,
[00:05:03.310]part of the field that has already been planted,
[00:05:06.610]the boxes or the
[00:05:09.970]the part of the planter that is passing over,
[00:05:12.940]what's already been planted will automatically shut off.
[00:05:16.480]So as not to double plant,
[00:05:19.360]that is very expensive for the farmers. And,
[00:05:24.160]it's wasteful of the seed.
[00:05:28.330]So we can use that,
[00:05:29.770]that method of technology in the planting also in harvesting,
[00:05:34.600]what we are able to do is we are to able to gather field maps
[00:05:39.340]that will generate a colored map at the end of the harvest.
[00:05:44.770]Each color represents a level of yield.
[00:05:47.980]So obviously the farmer's goal is to have the highest yield possible from
[00:05:52.900]their fields. Well, from this map,
[00:05:55.840]they're able to identify some of the lower yields are,
[00:06:00.920]which allows them to go out.
[00:06:02.510]Then post-harvest do some soil testing and identify,
[00:06:06.590]is there a nutrient that is missing from that area so that they are better able
[00:06:11.300]to apply appropriate nutrients and fertilizers to their field
[00:06:15.950]without being wasteful.
[00:06:18.920]When farmers are out spraying in the smer,
[00:06:22.100]also that same technology works with the sprayers.
[00:06:25.460]If the sprayer passes over a part of the field that has already been spread,
[00:06:30.110]that portion of the sprayer will automatically shut off so that we're not double
[00:06:34.580]applying any chemicals.
[00:06:36.940]farmers want to be very environmentally aware and
[00:06:41.630]also chemicals are again, incredibly expensive.
[00:06:45.050]And so farmers don't want to be wasteful of that.
[00:06:48.590]So as technology continues to evolve in agriculture,
[00:06:53.330]we have come a long way.
[00:06:55.340]We used to have to handpick our corn.
[00:06:58.970]Now we have machines that can, that can harvest,
[00:07:03.140]many rows at one time in great efficiency.
[00:07:07.070]Technology is allowing farmers to do their job better,
[00:07:10.520]to do it more efficiently and to do it safer.
[00:07:15.050]So what that allows them to do is the
[00:07:19.760]same thing that the wood pencil used to do...provides a different
[00:07:24.290]technology.
[00:07:26.240]ag technology continues to advanc. Agriculture
[00:07:30.260]appreciates the effort. Thank you.
