What fertilizer works well to improve compacted soil
When soil is compacted, you can first loosen it, then cover it with a layer of powder such as undecomposed cake fertilizer or poultry manure, then water it once to promote fermentation, which can make the soil loose. After fermentation, the nutrients seep down with the watering and can also provide nutrients to the plants. It should be noted that undecomposed raw fertilizer must not be applied in excessive amounts, as it easily causes root burn.
What are the prevention and control measures for soil compaction?
1. Soil testing and formula fertilization, and increased application of organic fertilizer. Apply fertilizer according to the formula based on soil test results. Through the combination of organic and inorganic fertilizers, supplementing deficient elements, applying chemical fertilizer to the soil will not only avoid causing soil compaction, but will also increase organic matter content. Increasing the application of organic fertilizer can improve soil structure and enhance the soil's fertilizer retention and air permeability, thereby preventing soil compaction.
2. Moderately deep plowing of the land; scientific and moderate deep plowing is about 35 cm. Using large tractors for deep loosening and land preparation, when the deep loosening depth reaches more than 30 cm, it can improve the deep structure and promote crop root growth. Thereby preventing soil compaction.
3. Effectively promote the return of straw to the field. Returning straw to the field can improve the soil's physical properties. Chopping and returning straw to the field can increase soil organic matter content, increase soil porosity, coordinate water, fertilizer, air and heat in the soil, create a good environment for soil microbial activity, and help decompose organic matter, soften and improve the soil's physical and chemical properties.
4. Remove residual film and plastic products from farmland. If residual film cannot be thoroughly removed after the use of plastic film, the plastic gel-like material remaining in large amounts in the soil will not only form toxic substances, but will also destroy soil structure.
The above is the relevant introduction on what fertilizer to use for compacted soil. I hope it is helpful to everyone.
