What should I do if the soil is hardened? How to solve this problem?

For this question, I will tell you in detail:

1. How is soil hardening caused?

1, soil erosion itself, when it comes to rainstorm or flood irrigation, water washes away, taking away the small molecular structure in the soil, reducing the void space in the soil, reducing the porosity and oxygen content, thus changing the soil structure and increasing the hardness of the soil when it comes to dry weather.

2. The organic matter content in the soil is very low. When the organic matter in the soil is insufficient, the growth and reproduction of microorganisms in the soil are hindered, and the activity of microorganisms themselves is greatly reduced, which directly affects the pH value of the soil and thus affects the formation of soil aggregates.

3. The content of acid salt in soil is too high, and the formation of too much acid salt is mainly due to the excessive application of chemical fertilizer in soil. For example, the content of phosphate in the soil is too high, and most of them are applied with too much phosphate, which can not be absorbed by crops and remains in the soil, forming insoluble phosphate and destroying the soil structure. Secondly, when nitrogen element is transformed in soil, it needs to consume organic matter. When nitrogen is excessive, the content of organic matter in soil will decrease, which will hinder the formation of soil aggregates and cause soil hardening.

Second, what effect will the soil board have on the growth of crops? Let's have a look.

1, soil hardening reduces void space, and the oxygen content and air permeability are poor. At this time, the root system of crops has poor respiration in the soil, which directly leads to the decrease of root absorption capacity and the decrease of nutrients supplied and transported to plants, resulting in poor growth of crops due to lack of nutrients.

2. Soil hardening increases soil hardness, directly affects the root system of crops, extends in the soil, and is limited in growth, resulting in underdeveloped root system growth, insufficient absorption of nutrients in the soil, and decreased crop yield and quality.

Third, how to prevent soil hardening?

According to the above reasons, the main source of organic matter in soil is organic fertilizer, so more organic matter should be applied. Enhance microbial activity in soil, expand soil space, increase porosity, improve soil physical and chemical properties and structure, and promote the good growth of crop roots in soil. At the same time, we should reduce the amount of chemical fertilizer applied in the soil, reduce the content of acid salts in the soil and increase the number of soil aggregates. Secondly, increase the microbial content in the soil, appropriately increase the application amount of biological bacterial fertilizer, and enhance the soil vitality.

I hope my answer can help you.
