Basic information of agricultural chemistry

Study on plant nutrition, soil nutrients, fertilizer management, pesticide risk assessment, agricultural product processing, crop composition and food safety management. (1) In terms of soil nutrients, the content, forms, transformation and availability of various nutrient elements in the soil, and the ability of the soil to supply nutrients;

(2) In the aspect of plant nutrition, it mainly studies the absorption and utilization of essential nutrients by plants, their physiological functions in the process of plant metabolism and their effects on plant growth and development;

(3) In terms of fertilizer properties, the nutritional components, physical and chemical properties and plant absorption and utilization of various fertilizers were studied.

(4) In the aspect of fertilizer application, the rational application of various fertilizers and their yield-increasing effects on crops were studied.

In a word, agricultural chemistry is based on soil, with plant nutrition as the center and fertilizer as the means to comprehensively study the relationship between them, and finally achieve the goal of improving crop yield. All methods include pot experiment, field experiment, agricultural chemical analysis, crop nutrition diagnosis, isotope technology, instrumental analysis technology and computer application technology.
