Raw chicken manure was used in the field, and the crops didn't grow well, saying it was salty. How to reduce salinity? With what?

Chicken manure must be fully decomposed before application, and parasites, their eggs and some infectious bacteria in chicken manure are inactivated through the process of decomposition (retting). After full decomposition, chicken manure will become a high-quality base fertilizer for planting crops.

According to the way of composting, it can be divided into four types: strip composting, trough composting, reactor composting and covered strip composting. Generally speaking, trough compost is the most popular in industrial production. However, when we farmers cultivate our own land, we still use it more widely to pile compost.

According to the requirement of oxygen, the decomposition of chicken manure can be divided into anaerobic fermentation and aerobic fermentation. The traditional method is sealed anaerobic fermentation of chicken manure, which takes a long time, usually 3~4 months to decompose. Now through biotechnology, aerobic fermentation can be used, and the decomposition speed can be 10~20 times faster than that of traditional methods. In addition, macromolecules such as protein in chicken manure can be decomposed into small molecules, which is beneficial to the direct absorption of crops.

In a word, the processing methods of chicken manure are varied and varied, each with its own advantages and disadvantages, but the processing technology is still imperfect and even disappointing. Summarize two treatment methods.

Strip composting is a kind of aerobic composting, and it is also the most widely used one at present.
