“I’m actually using two different Agri-Inject units. One is an Insectigator that I use to apply a mix of fungicide and insecticide on corn-on-corn, while the other is a 110 gph fertigation system that is used for split applications of nitrogen on corn. Articles I’ve read say that 100 units of nitrogen is all that corn can handle at one time. Of course, there’s no way we could put on the 275 units of nitrogen that we put on during the season in one or two applications. So we’re applying a large part of it through the pivot so the plant get it when they need it most. So far, I’ve been really pleased with the system and the results.”
“I’ve been using foliar applied nitrogen for three or four years now with very good results. The difference is, up until this last year, we’ve been putting it on with a crop sprayer. Now, with the use of an Agri-Inject pump, we’re able to put 32 percent nitrogen on the crop through our center pivot irrigation. Not only does this save on nitrogen, since we’re not putting it on the corners and only applying it where it can be used, but we save on labor, fuel costs and machine depreciation. It’s worked so well that I’m planning to buy a second Agri-Inject unit for this coming year.”
“We’re tissue sampling our corn and then using an Agri-Inject G110 to apply about 30 units of 32 percent liquid nitrogen through the pivot right before tassel. Last year, we had so much rain, we had trouble keeping our nitrogen levels up. We did see a response when we took tissue samples a second time after the application. In my area, most of the Extension specialists and seed companies are saying the most efficient way to get the maximum effect from your fertilizer is to do a late season application. We already have seven pivot irrigation systems, so this is really the direction we’ve been trying to go.”
“We buy between 200 and 300 Agri-Inject pumps per year that we resell to our customers for injecting sulfuric acid to balance pH levels. We’ve tried other pumps, but they just don’t hold up as well as the Agri-Inject models. Since the pumps are injecting from 93 to 98 percent sulfuric acid, we don’t want our customers having to touch them if there’s a problem. So if they see a leak, they shut it off and call us, and we’ll go out and do the repairs or maintenance ourselves. Even then, it’s usually a hose or the fittings rather that the pump itself. It’s not unusual to have Agri-Inject pumps on the job for 10 years or more. Then, what’s good about them is we can bring them back to our shop, rebuild them and they’re good for another 10 years.”

“We have a variety of liquid products we’re putting on barley and potatoes with Agri-Inject pumps. Our pivots are making a circle approximately every two days and there’s something being injected every time they go around from about late June until early August. That includes three different fertilizer solutions, as well as fungicides and pesticides that we put on using the same pumps. Most of our land consists of pretty sandy soil, so we have to put on the nitrogen a little at a time as the crop requires it. We’ve been using fertigation and chemigation since 1978, but this past year was only our second season with Agri-Inject pumps. We still have about eight pumps from another company, but we just ordered two more 85-gallon Agri-Inject units, partly because they’re so much easier to adjust and calibrate. ” Jeff Raybould Rexburg, Idaho
“I have an Agri-Inject G110 that I haven’t actually had a chance to use, due to all the rain we had last year. However, I did use a smaller Agri-Inject unit that the co-op owns to add a mix of micronutrients to one of our fields through the pivot. We took tissue samples and the co-op basically put together a blend of things like zinc, sulfur, boron, etc. based on the need. “I can’t really say how much it helped, because all the corn was good due to the rainfall. But I will say that the field where I injected the micronutrients was the best field of corn I had. Granted, it was also on the best soil I have; but I will certainly be doing it again. Since about 60 percent of our corn is under pivot irrigation, I’m also planning to use the Agri-Inject unit to put on 32 percent nitrogen pre-tassel, assuming it’s not as wet this coming season.”
