Increase the application of farm manure: agricultural fertilizer can be applied before planting crops, which can improve the activity of rhizosphere microorganisms, and farm manure must be completely decomposed before it can be applied.
Applying lime: Lime can increase the pH in the soil, but care needs to be taken to co-apply with farm manure to maintain soil fertility.
Added grass ash: Grass ash is also a good acidic soil conditioner and also contains a variety of mineral elements.
Add alkaline fertilizers: For soils that are not severely acidified, alkaline fertilizers can be applied.
First, increase the application of farm manure
In order to play a role in improving the soil, before planting crops, agricultural fertilizer can be applied, which can improve the permeability of the soil, improve the activity of rhizosphere microorganisms, and convert insoluble mineral elements in the soil into soluble nutrients, so as to achieve the desired purpose.
2. Apply lime
Lime is also a good acidic soil conditioner that can increase the pH in the soil, but it is necessary to pay attention to the co-application of farm manure to maintain soil fertility, otherwise the soil will dry out. At the same time, it is also necessary to control the amount of use, and cannot affect the normal growth of plant roots.
Third, add grass and wood ash
When improving the soil, you can add grass and wood ash to the soil, which can increase the pH of the soil, and it also contains a variety of mineral elements, which can add nutrients to the plant.
Fourth, add alkaline fertilizer
For soils where acidification is not serious, alkaline fertilizers such as sodium nitrate, potassium nitrate, nitro compound fertilizer, etc., cannot be mixed with ammonium fertilizers.
