Today, I am very happy to share with you some tips to improve the utilization rate of chemical fertilizers and grasp the concentration and purity of chemical fertilizers. Only in this way can we improve the yield and quality of agricultural products, increase economic benefits and protect the ecological environment to a certain extent, so scientific fertilization technology is needed. Fertilization is usually applied to the bottom or lateral bottom of seeds in advance. Keep a proper distance between the fertilizer and the seeds, usually three or four centimeters, and don't burn the seeds. Therefore, the depth of fertilization should be four or three centimeters.

According to experience, the average utilization rate can be increased from 30% to 40% after deep application of nitrogen fertilizer. Deep application of phosphorus and potassium fertilizer can reduce wind erosion loss, promote crop absorption and prolong fertilizer utilization rate, and the yield increase rate can generally reach 5% ~ 15%. Farmland fund fertilization is a simple and easy method, and there are two main methods: one is to spread fertilizer on the ground and then wash it on the ground; The other is to apply border fertilizer at the same time of farming, that is, apply border fertilizer at the same time of farming.

According to experience, the average utilization rate can be increased from 30% to 40% after deep application of nitrogen fertilizer. Deep application of phosphorus and potassium fertilizer can reduce wind erosion loss, promote crop absorption and prolong fertilizer utilization rate, and the yield increase rate can generally reach 5% ~ 15%. Through soil testing and analysis, determining soil nutrients and carrying out targeted scientific fertilization according to local conditions can not only reduce the application amount of chemical fertilizers, improve the utilization rate of chemical fertilizers, but also achieve the purpose of increasing production and income.

Fertilizer producers, general agents, wholesalers to retailers; Although fertilizer is packed in sealed plastic bags, I have seen many phenomena, such as rain, humidity, long storage time and caking. How to improve the utilization rate of fertilizer? The key to improve soil physical and chemical properties, scientifically determine the amount of fertilizer, scientifically select fertilizer types, adopt appropriate fertilization methods and periods, and improve fertilizer utilization rate is to determine the ideal amount of fertilizer. According to the demand law of crops for fertilizer and the supply capacity of soil fertilizer, we should adhere to the principle of supplementing what fertilizer with what fertilizer, and determine the ideal fertilization amount of crops.
