Since the development of agriculture, the use of a large amount of chemical fertilizers has caused soil problems, fruit quality problems, and increased planting costs. Agricultural output does not depend on the amount of fertilizer applied, but crop nutrition solutions. The core of the crop nutrition solution is to maximize land use, scientific planting management, efficient crop output, and higher farmers' income. The crop nutrition solution integrates soil improvement, fertilization and management through all stages of crop nutrition, ensuring the science and efficiency of the solution. To this end, crop nutrition solutions have strict standards and requirements for fertilizer products, technologies, services and extension systems.
