What fertilizer should be used to improve acidic soil? How to apply fertilizer to improve soil that is too acidic?

If you want to improve acidic soil, you can use farmyard manure, phosphate rock powder, lime nitrogen, ammonium bicarbonate, etc. Among them, farmyard manure can be used as a base fertilizer to increase the organic matter in the soil. Lime can also be used, or organic fertilizer can be added. In addition, there is calcium magnesium phosphate fertilizer, which is an alkaline fertilizer that can greatly improve acidic soil.

During the growth process, plants require a large amount of nutrients to supply the tree body and fruits. We artificially add certain amounts of various elements to plants.

During use, because some crops are not removable, a series of problems such as fertilizer abuse and large-scale use of chemical fertilizers cause soil hardening and acidification. So, how to deal with and improve the soil when acid hardening occurs?

Acidic soil improvement methods

For severely acidified soil, the simple and direct method is to apply quicklime. Quicklime has quick effects after use, can quickly increase the pH value of the soil, and quickly restore the production function of acidified soil.

However, the acid-regulating effect of lime is too intense, the dosage is difficult to control, and the duration of effect is short. However, long-term excessive application will also cause the soil to be alkaline and soil compacted, which is detrimental to root growth. It is generally only suitable for use when the soil is not planted with crops.

How to fertilize acidified soil

1. Organic fertilizer and microbial fertilizer

We can increase the use of organic fertilizer and microbial fertilizer through the buffering effect of organic matter , to adjust soil acidity. Water-soluble fertilizers containing humic acid also have good effects on buffering and adjusting soil acidity and alkalinity.

2. Alkaline fertilizer

Another method is to increase the use of physiological alkaline fertilizers, such as calcium fertilizer, magnesium fertilizer, etc. We can also use soil conditioners made from shells, oyster shells, and corals that contain calcium, magnesium and other elements to safely adjust soil acidity.

3. Fertilization period

To avoid soil acidification in healthy soil, it is recommended to apply fertilizer during the crop topdressing period. Give priority to macroelement water-soluble fertilizers, which are physiologically neutral fertilizers that do not easily cause soil acidification.

Once again, regularly apply fertilizer containing humic acid, amino acids and microbial inoculants. This can not only replenish soil organic matter, but also improve and buffer soil acidity.
