How do acidic soils maintain fertilizer efficiency? For acidic soils, the fertility of fertilizers is not easy to maintain. The following points can be summarized by using the limestone to neutralize the acidity of the soil, and evenly apply during the preparation of the soil. In a few years, until the transformation into neutral or slightly acidic soil, it is beneficial to the efficient use of fertilizers for crops.
For acidic soils, new fertilizers can also be used, such as growing green manure and increasing organic matter. How to maintain the fertilizer effect of acidic soil? Application of alkaline fertilizers such as calcium magnesium phosphate fertilizer, phosphate rock powder, plant ash, ammonium bicarbonate, lime nitrogen, ammonia water, etc. can also alleviate acidity, neutralize and improve the acid soil, everyone in the planting process Give it a try.

1. Adding farmyard manure and cultivating soil fertility crops Before planting, the farmer's fertilizer is used as the main fertilizer to increase the organic matter in the soil, improve soil permeability, promote rhizosphere microbial activities, and promote the insoluble mineral elements in the soil. As a soluble nutrient, the effect of fertility is achieved.
2. Appropriate application of lime acid field When planting the soil, lime is applied year by year, and 10 to 40 kg per mu is applied every year until it becomes slightly acidic or neutral.
3. Plant acid-tolerant crops, such as mung bean, rapeseed, buckwheat, and rice, which are resistant to acid crops. Soil acidity is adjusted by soil management through land preparation management.
4. Implement water and drought rotation, improve physical and chemical properties, improve cultivation techniques, prevent soil erosion, and implement water and drought rotation in acid soil (changed once every two to three years) to improve soil ploughing and physical and chemical properties, and to carry out post-sow cover film during cultivation. Adjust the replanting methods (such as rice-rice-rice, change to rapeseed-rice-rice), and use alkaline fertilizers (such as ammonium bicarbonate, ammonia) for improvement purposes.
