 This farm right here is River Bottom Land and there's, I can't remember exactly, there's about eight or ten different types of dirt here and they're from one extreme to the other. And so what we were running into irrigating here was we'd have a row that was, you couldn't even walk across it was so wet and then right next to it would be Wilton from Neaton Water. So the first thing I did once we got everything installed was, I knew what crop was going on the pivot. I called Zematica and I said okay we've got this crop going in. I said what's my prescription need to be? And they laughed at me and they said we don't do that, you do that. And so what I did was I read the description and the water capacity of these different types of dirt and I basically formed it into, I think I've got three or four different sowns, maybe five. So I had my base prescription and the more sand your dirt got a little bit more and the more wet nature dirt got a lot less. When we discuss about the project that we conducted this year we discuss the use of soil sensor technology to support irrigation scheduling meaning to support decisions of when to irrigate and how much to irrigate. So the first thing that we did this year was we collected soil samples to really ground truth to determine whether or not you know the soil type and soil texture of this map was correct and also the extent of these soil units. We also brought a sensor that collects soil electrical conductivity data so with the soil electrical conductivity data we also brought a high accuracy GPS because we know that there are differences in topography and then we combined soil electrical conductivity data, soil texture data and the topography or elevation map into a new map. When you started looking at the soil sensor data you saw that maybe you know your baseline zone got probably much smaller and probably was split into two that maybe this field that you know you have two different soil types maybe there was only one soil type and then this area that you found as sandy you know it was much larger. Yeah and it was and it's not so much on top it is it is come to find out that dirt after I researched a little bit more about that little field right there it's got a really shallow or high groundwater table right there and by looking at it and by the soil maps that you don't realize that but it's actually there and the soil sensors pick it up. Between the variable rate irrigation and the soil sensors I mean this technology is very very important. Well we used to just irrigate a straight rate and since we've gone to variable rate I would I would feel safe and guess and we're probably saving at least 60% water usage on that pivot and on top of that with the sensors you could possibly even save more or maybe use a little more to get the crop you know to achieve your goals on your crop.
