How Is Soil Salt Harm Produced?
Jan 19, 2018

The formation of soil salt damage has the following several aspects:

1. Large amount of chemical fertilizer application

Blindly increase the dosage of chemical fertilizer cannot increase production, and it will do harm to plants. Excessive application of chemical fertilizers, especially ammonium nitrate, will make the soil salt content increased, residual salt insoluble. Year after year, the phenomenon of soil salinization will inevitably occur.

2. Imbalance in fertilization

Apply a large amount of nitrogen, phosphorus and potassium fertilizer, but do not pay attention to the supplement of trace elements, or the imbalance of organic fertilizer and inorganic fertilizer, will cause soil salt damage.

3. Special environmental

There is no precipitation in the shed for a long time, so that a large number of chemical fertilizers cannot penetrate into the deep soil. Coupled with high temperature and evaporation, the salt is easily rising to gather in topsoil.

4. High soil moisture

In the greenhouse, the soil moisture is large, which destroys the soil aggregate structure, the large porosity is reduced, and the soil permeability is poor, so it is easy to form a compaction.
