How fertilizer affect the soil?

Fertilizer is an expensive input needed to optimize crop production. Understanding how fertilizers react in the soil is important to optimize the amount of fertilizer used and the efficiency of growing high-yielding crops. It is also important for farmers to understand the short and long-term effects of fertilizers on soil chemical and biological properties.
Fertilizer when to apply？

The fertilization method of potted plant fertilizer is different in each season. The spring and autumn season is the growing period of plants, and the demand for fertilizer is relatively large, so the amount of fertilizer needs to be increased. A small amount of fertilizer in summer, summer evening is the best time to fertilize, to avoid sunburn. When plants stop growing in winter, no fertilizer is needed.
