Ammonium Nitrate, Grade B, is a concentrated granular nitrogen fertilizer designed to supply agricultural crops with nitrogen during the early spring period, as well as after mowing or grazing to stimulate regrowth, vigorous growth, and development of green plant mass. It contains equal proportions of ammonium and nitrate nitrogen, making it a universal and highly effective mineral fertilizer. With prolonged use, periodic liming is necessary, because it has an acidifying effect on soil.
