Nitrogen (N) management plans are about as variable as the timing and application options available to today’s no-till farmers. Not only is careful consideration given to the types and amounts of N applied, but the use of precision data gathering equipment also enables growers to gauge their success on the fly and take corrective actions as required.
Timing also involves not only in-season application adjustments, but the previous season’s results require decisions be made on the use and types of cover crops to serve as another N source.
Knowing how important proper N management is to both cash and forage crops, No-Till Farmer’s editors recently surveyed readers about their N management strategies, the results they’ve seen and any upcoming plans for 2018.
I have made a couple of major changes over the years in nitrogen management. I moved toward sidedressing the majority of the N on corn as opposed to applying pre-plant urea both with and without Agrotain. I reduced my total N from 225 units to 170 to 190 units and began injecting the N instead of laying it on top.
I’ve observed better yields and fewer years of late season N deficiency symptoms. I sidedress approximately 150 to 155 units with 32% UAN and average 35 to…
