The amount of trace element fertilizer
What is the application amount of medium and micro fertilizers for various crops? The application amount of medium-element element fertilizer is roughly equal to that of N, P and K fertilizers, and even more, while the amount of trace element fertilizer is less. For example, the majority of field crops per mu, zinc sulfate is only 1 to 2 kg, and only borax is used. 0.5 to 1 kg. Fruit crops, such as fruit trees and vegetables, are higher, generally no more than 3 to 5 kilograms per mu. Therefore, after the sowing or transplanting of the micro-fertilizer and the tidal dry soil or decomposed organic fertilizer is mixed uniformly, it is applied together with the basal fertilizer or applied. In addition, most of the micro-fertilizers and phosphate fertilizers will form insoluble substances, which will reduce the effect of each other, so do not mix them together.
