Take a multi-pronged approach to improve fertilization methods

Deep application of nitrogen fertilizer mainly refers to ammonium nitrogen fertilizer and urea fertilizer. According to statistics from the Ministry of Agriculture, while maintaining the same yield of crops, deep application of fertilizers has a significant effect; deep application of ammonium nitrogen can increase the utilization rate by 31%~32%, urea can increase by 5%~12.7%, and ammonium sulfate can increase 18.9%~22.5%. Phosphate fertilizers are applied intensively in accordance with the principle of heavy drought and light water, which can increase the utilization rate of phosphate fertilizers and reduce soil pollution. Can also use quicklime, adjust the soil oxidation-reduction potential and other methods to reduce the absorption and accumulation of heavy metal elements by plants, and can also use methods such as plowing, cutting and deep plowing and soil replacement to reduce soil heavy metals and harmful elements.
