Harm and prevention measures of soil hardening (soil hardening treatment and solution)

There are many reasons for soil hardening, such as long-term use of chemical fertilizers and pesticides, too little use of organic fertilizer, too much no-tillage planting, too much rotary tillage, less tillage and other factors, which will cause soil hardening, reduce soil permeability and be unfavorable to crop growth.

What are the measures to change soil hardening?

There are many reasons for soil hardening, such as long-term use of chemical fertilizers and pesticides, too little use of organic fertilizers, too much no-tillage planting, too much rotary tillage, and too little tillage.

These factors will cause soil hardening, reduce soil permeability, which is not conducive to the growth of crops.

According to the causes of soil hardening, the following three improvement methods can reverse the persistent occurrence of soil hardening and effectively improve the soil.

① Increase the application of organic fertilizer.

Organic fertilizer is one of the most effective methods to improve soil. Applying a large amount of organic fertilizer to soil often can effectively improve soil hardening.

After organic fertilizer is applied to the soil, more microorganisms will be produced after soil decomposition, and various nutrients needed by plants can be released.

At the same time, organic fertilizer can improve soil structure, adjust soil moisture, fertility, heat and gas, thus enhancing soil permeability, reducing soil hardening and improving soil fertility.

There are many kinds of organic fertilizers. In rural areas, we can use human and animal manure, plant straws, stems and leaves, weeds, or residue after plant pressing, cake fertilizer and so on.

After effective corruption, it can be applied to cultivated land as organic fertilizer, which has a very good effect on soil improvement.

② Reduce the use of chemical fertilizers and pesticides.

At present, in agricultural production, fertilizers and pesticides are almost indispensable, and they do have immediate effects on crop production.

However, many of these chemical products are difficult to be degraded by soil due to long-term and large-scale use.

These chemicals, which are difficult to melt and degrade, are more harmful to the soil and will lead to soil hardening.

In the current planting industry, chemical fertilizer has to be used because of production habits, but in use, the investment can be appropriately reduced and organic fertilizer can be used instead of chemical fertilizer.

Use pesticides to control pests and diseases, and adopt physical control or natural enemy control methods. It can not only reduce the pollution of soil and crops, but also play a vital role in soil improvement.

③ Deep tillage and intensive cultivation

At present, due to the low economic benefits brought by agricultural production to farmers, farmers often take time-saving measures in planting methods in order to reduce planting costs.

For example, no-tillage planting, rotary tillage planting, etc. Often carried out. This planting method is really simple, and it can also reduce the capital investment in agricultural production.

However, due to the solidification of soil structure, it can not be improved, and it will lead to soil hardening over time.

Therefore, even if the economic benefit of agricultural planting is not high, since farming is chosen, it should be planted with heart, although no-tillage or rotary tillage can be used.

However, the soil should be deeply ploughed every two years, and the surface and deep layers of the soil should be rotated in an all-round way to improve the structure of the soil and reduce the occurrence of soil hardening.

To sum up, most of the causes of soil hardening are caused by improper artificial planting methods. Planting with modern production means and methods can really increase the yield in a short time. But after a long time, the harm to the soil is obvious.

Therefore, considering the long-term plan, to improve soil compaction, we still need to start from the source, and fertile and excellent soil can grow crops for a long time.
