Fertilizers also have the relationship of "relative life" and "phase-g". In order to prevent the "phase g" between fertilizers, the following four points should be made:
The first is to balance fertilization as much as possible. The application of multiple fertilizers to crops not only wastes fertilizer, but also results in the lack of other certain or certain nutrients. Second, according to the proportion of demand for various nutrient elements in different crops, it is necessary to increase the same and to reduce the same. The third is staggered application period or application site. Such as zinc fertilizer and phosphate fertilizer will be combined with each other, so the phosphate fertilizer should be used as base fertilizer or basal fertilizer, zinc fertilizer should be applied as top dressing. The fourth is to narrow the scope of contact. For example, dressings, soaking seeds, and roots can be applied to trace fertilizers to limit the trace elements in the smaller area of ​​the root, and to avoid contact with a large number of elements.
