How to improve soil acidification

1. Lime application: After autumn harvest, quicklime can be applied to the soil to adjust the pH value in the soil. 2. Fumigating fire dung: burning weeds and straws in the field to control acidification. 3. Precise fertilization: When planting crops, fertilize them according to the needs of the plants and reduce the amount of chemical fertilizer applied.

How to improve soil acidification 1 and lime application

To improve the problem of soil acidification, we can clean up the straw weeds in the soil after the autumn harvest, then apply quicklime to the soil, and apply 100 kg of quicklime per mu, and then plough the soil once to adjust the pH value of the soil to make it neutral.

2. Smoked fire dung

When improving the soil, we can smoke fire dung, which needs to be burned with straw and weeds in the field. Smoked fire dung is alkaline, which can neutralize the acidity in the soil, and contains a lot of potassium, which can maintain the balance of acid and potassium in the soil.

3. Accurate fertilization

In order to improve the acidified soil, it is necessary to apply fertilizer accurately. It is necessary to determine the elements contained in the soil and the elements lacking, and then apply fertilizer according to the needs of crops, so as to reduce the application amount of chemical fertilizer and achieve the purpose of preventing acidification, and it is best to apply organic fertilizer to crops, because organic fertilizer has greater buffering capacity.

4. Covering cultivation

When planting crops, it is best to adopt the method of covering cultivation. It is necessary to cover the soil with a layer of plastic film or straw to reduce the erosion of water on the soil, thus slowing down the loss of alkaline alkali in the soil. Moreover, when applying nitrogen fertilizer to crops, ammonium hydrogen phosphate can be applied to them to avoid soil acidification.
