How to Improve Irrigation Water Quality for Better Crop Performance
12 Feb 252m 36s

At Farm Con 2025, Kelly Garrett and Kurt Grimm from NutriDrip discuss the critical role of water quality in agricultural productivity. Over the years, Garrett discovered that declining yields and product efficacy issues on his farm were linked to water contamination rather than input performance. Common water contaminants, such as bicarbonates, sodium, and other ions, disrupt nutrient availability and reduce the effectiveness of fertilizers and herbicides. Lowering pH—preferably below 6.5—can help mitigate these issues, but it requires thorough lab analysis and targeted treatments before application.

00:00:00 Water quality and fixing your water problems. It's one of the things that we're gonna be talking about more in 2025. 00:00:05 We've already kind of covered this, you and Mike Evans. It's a big, big topic. You found out a couple years ago, Kelly Garrett, that you, um, have some bad water. 00:00:12 And then you said, the more I dug into this, more I realized it wasn't product problems. It wasn't product, uh, efficacy issues, it was 00:00:19 water contamination, water problems. And here we're at Farm Con 2025 with our man Kurt Grimm, with our, uh, Nutri Drip, 00:00:25 and we're talking about water quality. This is a bigger issue than we even knew about a few years ago. 00:00:29 It is. We've identified that water specifically. Well, water typically has something in it that is binding things up. 00:00:36 It's either bicarbonates, sodium, there's different salts in the water, ions, ions. It's a, it's a balance that 00:00:43 that's getting outta whack when we irrigate. It can happen in spray water. So it's something that Kelly's identified on your farm. 00:00:48 Maybe speaking to that a little bit, what, What problems does it cause Bicarbonates tie up the fertility bicarbonates hurt the, uh, efficacy 00:00:56 of the herbicides and the chemicals and the foliar that go out. My surface water irrigation, which is about half of 00:01:02 what my acreage, the yields continue to climb. Yep. My well, water irrigation, the yields have leveled off. So we know it ties up nutrients 00:01:10 and it causes problems. How do we fix it? So there's different ways. Probably the main thing is lowering pH 00:01:16 that's lowering pH removes bicarbonate. If we can get that pH of the irrigation or spray water down under six and a half to six. 00:01:23 So there's some targets we've gotta hit, we've gotta do lab analysis, we've gotta find out what's in it, 00:01:27 figure out how to offset it. So there's some things that can be done to treat, But you can't change, you can't change the pH. 00:01:31 So it's, it's all after, it's all treatment that goes in from ground to, uh, before it goes out and gets sprayed or applied. 00:01:38 That's correct. Yep. And this is something we're seeing on center pivots, drip irrigation, flood irrigation, 00:01:43 it affects any kind of irrigation, um, that's being done. We're seeing this on, on 00:01:48 any kind of system. And you're hearing it More than you did a few years ago. Absolutely. Is it because of the problems worsening or 00:01:52 because we're getting smarter about detecting it? It's because one, that the number one change that's happened in the last 10 years is the pH 00:01:59 of rainfall has, or it's actually over the last 30 years, has, has risen from about four 00:02:04 and a half to six to six and a half. So every time it rained, it would fix our soil. It's not doing that anymore. 00:02:09 Acid rain is no longer a thing your soil takes on the properties of your water. Our well water's bad. 00:02:15 Kelly Garrett, Kirk Grimm coming at you from Farm Con 2025, you'll be, if you tune into our stuff here at Extreme Ag, 00:02:21 we'll be talking more about water quality and amendments we can do to make your water quality better. You know what? If you're spending the money, you're doing 00:02:25 the work, it turns out your water's a problem. It's probably a fix that really needs to be addressed A hundred percent.
