Allganic® Nitrogen Plus 15-0-2 is an OMRI listed product in the form of dry, flowable granules that provides 100% water soluble natural nitrogen. It is a sustainable source of nitrogen in the form of nitrate, originating from natural rock deposits in the Atacama Desert in Chile. For best results, it is recommended to apply this product during periods of low temperatures, when soils cannot produce nitrogen in the form of available nitrate. This ensures maximum efficiency even with small applications.
