What to do if the soil is not fertile
During the cultivation of crops, most nutrients are obtained from the soil. Therefore, it can be said that soil is a key factor in growing crops. Whether soil fertility can affect the yield and quality of crops. However, my country’s soil types are diverse, including acidic soils and saline-alkali soils, heavy clay soils, and sandy soils. The fertility and nutrient content of each type of soil are not exactly the same. How can we make the soil more fertile during the planting process and more conducive to the growth of crops?
First, increase the amount of organic fertilizer application
Organic fertilizer contains a large amount of organic matter, and is rich in nitrogen, phosphorus, potassium and various other polluting elements. Use has the opportunity to effectively improve soil fertility, increase the content of organic matter in the soil, improve soil porosity, and improve the physical and chemical structure of the soil. At the same time, organic fertilizer contains a large number of microorganisms, which increases the microbial activity in the soil and improves the soil’s air permeability. Organic fertilizers are used in many poor soil improvement processes, and the effect is very significant.
Second, appropriately increase guest-land replacement
For some nutrient-poor soils, adding guest soil can be used to increase soil nutrients and make the soil water, gas and heat conditions more coordinated and balanced. In particular, adding some forest guest soil with higher organic matter or humus content is very good for improving fertility. If conditions permit, you can also use fertile and light farming soil mixed with organic fertilizer to prepare nutrient soil for better results.
Third, intercropping green manure
Intercropping green manure is a very important measure in the soil improvement process. Because green manure has high yield and good fertilizer efficiency, it can increase the organic matter content of the soil, improve the physical and chemical properties of the soil, and prevent soil erosion. At the same time, chlorine fertilizer can also be used as a cash crop to increase farmers’ income. In the planting process of many crops, intercropping green manure can play a very good role in improving soil fertility.
Fourth, implement a crop rotation system
Crop rotation is also an important measure to enrich the soil. Because many crops have a high demand for certain specific elements during the production process, if they are planted for a long time, it may cause a lack of certain elements in the soil, causing crop deficiencies, resulting in poor yield and low quality of the plants. result. Through agricultural rotation, different crops are planted to improve the fertility demand of the soil, making the fertility in the soil more balanced, so that crops can be better grown.
Fifth, reasonable and balanced fertilization
In terms of the application of chemical fertilizers, for some relatively poor soils with poor fertilizer supply capacity, fertilizers must be used in a balanced manner, and nitrogen fertilizers or other fertilizers must not be applied exclusively. Nitrogen, phosphorus, potassium and various trace element fertilizers should also be used in a balanced manner. The purpose of this is to effectively fertilize the soil so that the nutrients in the soil are more balanced and will not cause a lack of soil fertility.
Sixth, work hard and carefully
For soils with poor fertility, we can also achieve the purpose of fertilizing the soil by increasing the depth of the tillage layer and replacing the surface soil with the bottom soil. This requires deep plowing and careful cultivation during the farming process. The bottom soil must be dug out and dried to kill pests and diseases, thereby improving the soil’s air permeability, maintaining water and soil, and preventing fertility loss.
In addition, for adverse conditions such as soil acidity or alkaline soil, comprehensive measures must be actively adopted to improve the soil. For example, increasing the amount of lime applied in acidic soil can achieve the purpose of acid-base neutralization. For example, acidic fertilizers and some soil improvement conditioners are used in saline-alkali soil to improve the physical and chemical properties and fertility of the soil, making it more suitable for crop growth and increasing yield and quality.
