How to quickly solve soil compaction?

Soil compaction often causes the soil surface to become hard, cracks to appear in the land, and a decrease in the soil's ability to retain water and fertilizer. If not handled in time, it can easily lead to poor crop growth and reduced yield. So how can we quickly solve the problem of soil compaction? Let’s learn more about it below.

1. Increase the application of organic fertilizer

Organic fertilizer not only provides nutrients for crops, but also improves the physical properties of the soil, enhances permeability and water retention, and provides food and energy for microbial activities.

2. Balanced fertilization

Implement balanced fertilization, do not apply fertilizer of a certain element biasedly, and do not use a certain chemical fertilizer for a long time, such as applying compound fertilizer or urea to the soil for a long time. Several fertilizers should be used alternately to reduce the accumulation of certain harmful substances and avoid soil compaction.

3. Reasonable crop rotation

Crop rotation can reduce excessive consumption of soil nutrients caused by continuous cropping of the same crop, avoid excessive accumulation or deficiency of a certain nutrient in the soil, and thus maintain the balance of soil nutrients. Specifically, the planting sequence and rotation cycle of crops should be reasonably arranged according to the growth characteristics of crops, nutrient requirements and their impact on the soil to minimize the occurrence of soil compaction.

4. Strengthen deep tillage and land preparation

Deep tillage can effectively break up the plow bottom layer, improve the structure of the tillage layer, coordinate the relationship between water, fertilizer, air and heat in the soil, and create conditions for large-scale activities of microorganisms.

5. Returning straw to the fields

Crushing the straw and returning it to the field can greatly increase the organic matter in the soil, prevent soil compaction, reduce the use of potassium-containing fertilizers, and effectively increase crop yield and quality. There are generally two correct ways to return the crop straw to the fields. One is to crush and press the crop straw back to the fields, which is to crush the crop straw and then press the straw into the soil through deep plowing to mix it with the soil. The other is to cover the crop straw back to the fields, which is to crush the straw and then cover the ground directly.

6. Use soil conditioners

Reasonable use of soil conditioners, such as silicon, calcium, and iron in the conditioners and organic and inorganic colloids in the soil can quickly form soil aggregate structure, solve the problem of soil compaction, and promote the growth of crop roots.

In general, soil compaction is an important factor that restricts the high quality and yield of crops. It is usually caused by people's long-term or single application of inorganic fertilizers, no or little application of organic fertilizers, which destroys the stability of the soil structure. Therefore, it is necessary to solve the problem in time.
