MacRoy Series G Metering Pumps Accuracy and reliability for large-volume fluid injection. “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 plants get it when they need it most. So far, I’ve been really pleased with the system and the results.” - Joel Armistead, Adairville, Kentucky Higher Yiel

MacRoy Series G System Pumps For High Volume, Top Efficiency “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...
