Usage: Industrial is used in the production of Dicyanamide, Cyanamide, Thiourea, polymycin, amino guanidine carbonate and other main raw materials.

Lime nitrogen contains 20%~28% lime, is alkaline fertilizer, can not be mixed with ammonium sulfate, ammonium bicarbonate, calcium perphosphate and other fertilizers, so as not to cause nitrogen evaporation loss and reduce the effectiveness of phosphorus. Lime nitrogen suitable for use in acidic soil, rice, barley, wheat, corn, sweet potato and other crops have good results
