 So we've had such an interesting year. We had a lot of water early, a lot of rainfall, some real heavy rainfall flooding that compacted our soils to seal them over. And then now we've had several weeks in places of very hot, dry weather with a lot of crop water demand. And it's really made it interesting to figure out when we need to irrigate. Obviously, when it does a rain, we're going to have to irrigate to meet crop water demand, but when we get these small rainfall events and we've had saturated soils, when do we start back up? Makes these decisions challenging. What I think works best for us in our region are using soil moisture sensors to help make those decisions. Any kind of soil moisture sensor works, they're all, in my opinion, the same. They all give you the same information. I personally teach people to start off with watermark sensors. They are a simple low-cost tool that costs about $35 a piece and you can put them together. You can read them manually with a manual reader like this that costs about $200 or you can spend more money on a telemetry unit that costs maybe $1,000 per unit, but you can see that on your phone or your iPad. You can see it and don't have to walk out in the field to read them. In soybeans, we've done paired studies with farmers on their farms using computerized soil selection, pipe planner, faucet, surge irrigation, and soil moisture sensors. These three tools, in soybeans, they reduce water use and save enough water to pay for the equipment, so there's no difference in that returns. Essentially, what happens is the energy savings pays for the equipment. Using corn. It does more than that. It actually puts money in your pocket anywhere between $25 to $39 an acre more because we're making another six and a half bushels. Even just having a set of four to five manual read sensors, maybe one or two telemetry units across your landscape, will really help you understand what's going on in your field, where are we out in the soil water balance, and when do we need to start back up and can we wait on a rain. With the sensors, we know how much we have available. We look at rainfall. If we get any rainfall in that time period, we know what the difference is. We get the rain we're done, if we don't, that's how much we need to finish it out. It's a really simple decision at the very end. So the app's available on the app stores. On Apple, it's the app store. It's under Arkansas Soil Moisture Calculator, or Arkansas Watermark Tool. It's also on Android, on the Play Store. You put in your numbers, so the app does all the calculations for you, counts for the rooting depth, you're allowable depletion, how soon do you want to irrigate, how much safety factor do you want to have, it counts for your growth stage. You put your growth stage in, then we know how much you need to finish out, how long your irrigation set time is. So in less than a minute, you can take readings and figure out how much water is left in the profile, and then app goes ahead and automatically calculates how long, when do you need to start your pump up again. So it tells you in three days, or four days, or two days, or ten days. And also it tells you then how much water is going to be required to finish that crop out for the season. So then you can also predict how many more irrigations you're likely to need. What I always tell people is, when you first put sensors out, I can almost promise you, what you think is going on in your field is not what's really going on, and the sensors are going to surprise you and you're going to really question whether they're working right. And you're going to have to kind of rethink and relearn about what you think is really going on in your field, and every field is a little different.
