In order to increase the promotion and application of slow-release fertilizers, Anhui Liuguo Chemical Industry Co., Ltd. recently succeeded in the trial production of 600 tons of diammonium phosphate in Hebei, Henan and Shandong. The initial use of experimental data shows that it is particularly effective for increasing yields of cotton and spring corn. According to reports, this product adds a new generation of controlled-release activated synergists, mainly composed of fertilizer nutrient controlled-release agents, biosurfactants, bio-fermentation compound amino acids, and soil structure improvers. Its main function is to control the loss of nitrogen decomposition, reduce the fixation of phosphorus, activate the fixed phosphorus and potassium in the soil, loosen the soil and increase the granule structure of the soil, enhance the permeability, and promote the absorption of nutrients by plants. It is reported that the use of this product can increase the utilization of phosphorus and nitrogen by more than 20%.
