Abstract: Fertilization is an important process to improve soil fertility and promote crop growth, and it needs to be implemented many times in most of the crop growth process, and the rational application of fertilization technology has a positive effect on increasing crop yield, improving the physical and chemical properties of farmland soil, and reducing production pollution.This article analyzes and summarizes the current situation and existing problems of agricultural fertilization, provides the characteristics and commonly used fertilizer types of field fertilization technology, explains fertilization precautions, and designs low pollution fertilizer use plans. It is hoped to promote the standardized implementation of field fertilization operations and improve the green and environmental protection level of agricultural production.
