What kind of fertilizer is used in the consolidation of land?
When the land is consolidated, it can first loosen the soil, then cover a layer of uncooked cake fertilizer, poultry manure and other powder, and then pour water once to promote its fermentation, which can make the soil loose. The fermented nutrients infiltrate with watering, and can also provide nutrients for plants. It should be noted that unripe raw fertilizer should not be used too much, which can easily lead to root burning.
What are the prevention and control measures of soil consolidation?
1. Soil testing, formula fertilization and increasing application of organic fertilizer. According to the results of soil test formula fertilization, through the combination of organic and inorganic, lack of elements, so that the application of chemical fertilizer into the soil will not only not harden the soil, but also increase the content of organic matter. The application of organic fertilizer can improve soil structure, enhance soil fertilizer conservation and air permeability, so as to prevent soil consolidation.
2. Moderate deep ploughing, scientific moderate ploughing is about 35 cm. The use of large tractors for deep loosening and soil preparation can improve the deep structure and promote the growth of crop roots when the depth is more than 30 cm. So as to prevent soil from hardening.
3. Effectively promote straw returning to the field. Straw returning can improve soil physical properties, straw crushing and returning can increase soil organic matter content, increase soil porosity, coordinate soil water, fertilizer, gas and heat, and create a good environment for soil microbial activities. it is beneficial to the decomposition and softening of organic matter and the improvement of soil physical and chemical properties.
4. Remove residual film and plastic products from farmland. If the plastic film can not be completely removed after the use of plastic film, a large number of plastic colloidal tape will not only form toxic substances in the soil, but also destroy the soil structure.
The above is the introduction of what fertilizer is used in the consolidation of land. I hope it will be helpful to everyone.
