◉ Service Background
The degree of soil being excavated and utilized is getting higher and higher. Fertilizers can provide plants with one or more essential nutrients. They are important substances to improve soil properties, increase soil fertility, and regulate crop growth. Therefore, fertilizers are needed to supplement these nutrients. Nowadays, the fertilizer market is mixed, product quality varies from good to bad, and fertilizer fraud scandals are common. How to choose fertilizers wisely is of vital importance. It is necessary to accurately understand fertilizer quality problems and strictly control the quality and safety risks of product planting, fertilizer production, circulation, and sales.
