Slow Release Nitrogen Liquid Fertilizer

SRN 28 is a nitrogen fertilizer that contains the highest percent of slow release nitrogen of any slow release product at 72 percent. The benefits are that a small but steady supply of nitrogen is available to your crops over a period of up to six weeks, so it won’t limit growth. Since the amount of nitrogen available at any one time is small, the risk of leaching is also relatively small, so SRN 28 fertilizer is more environmentally-friendly.
