Reasons for soil acidification: precipitation or watering is large and concentrated; long-term large-scale application of chemical fertilizers, most of which are currently acid fertilizers.
Solution: Pay attention to the application of high-quality organic fertilizers, increase the content of organic matter in the soil, and fertilize scientifically. At the same time, pay attention to the application of microbial fertilizers and soil conditioners, increase the number of beneficial microorganisms in the soil, and maintain the fertility of the soil.
The reason for the imbalance of soil nutrient ratio: Crop growth requires 17 essential nutrient elements, and in daily management, only the application of nitrogen, phosphorus, and potassium fertilizers is emphasized, and the middle and trace element fertilizers are ignored, resulting in the exhaustion of trace elements in the soil and the accumulation of large elements.
Solution: apply more organic fertilizer. Organic fertilizer can increase soil humus, is conducive to the formation of aggregate structure, improves soil aeration, water permeability and nutrient conditions, and can decompose and release some solidified nutrients to the soil.
Apply medium and trace element fertilizers. Unreasonable use of chemical fertilizers will lead to the lack of trace elements, which must be supplemented in time and accurately to achieve a good harvest.
Pay attention to extra-root top dressing (foliar fertilizer). Foliar fertilizer can replenish the missing elements to plants in time.
