Yifeng Machinery-What are the types of fertilizers?

1. Liquid fertilizer applicator, chemical liquid fertilizer has a strong corrosive effect on metals and is volatile. Therefore, except for some liquid fertilizers, which can be applied to crop stems and leaves by spray method, most of them need to be applied to the soil to prevent volatilization, loss of fertilizer efficiency and burning of crops. Liquid fertilizer is composed of human, animal manure, urine and sewage.It often contains suspended solids or impurities. After fermentation treatment, it is diluted with water, filtered and then sprayed.

2. Pneumatic wide-format fertilizer spreaders, and then we have developed a variety of types of pneumatic wide-format fertilizer spreaders abroad. In recent years, the working principle is roughly the same. They all use high-speed air flow generated by high-speed rotating fans, and cooperate with mechanical fertilizer dryers and sprinklers to spread fertilizer, lime and other soil improvers in a wide and efficient manner.

The liquid fertilizer trencher should meet the following performance requirements：

②the outlet of liquid fertilizer should not be blocked, and the liquid fertilizer should flow out from the side hole near the lower end of the drain pipe.

③In order to cover the applied liquid fertilizer tightly in time, the liquid fertilizer trencher should not hang grass and affect the normal flow of the soil.

The fertilizing machine we are using now mainly uses liquid ammonia as a colorless and transparent liquid, which contains 82.3% nitrogen. It is an industrial raw material for the manufacture of nitrogen fertilizer. The price is 30-40% lower than that of solid fertilizer, and the fertilizer effect is fast and the production increase effect is significant.Therefore, the amount of liquid ammonia applied in developed countries accounts for a considerable proportion of nitrogen fertilizers.
