MacRoy Series D Metering Pumps Economical accuracy and reliability for fluid injection systems. “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.” — David Grant, Rutherford, Tennessee

MacRoy Series D System Pumps High accuracy, reliability and easy to use. “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...
