As long as the amount of fertilizer is controlled, the damage will be greatly reduced. Generally, the application of ammonium bicarbonate per mu shall not exceed 30 kg, and the urea shall not exceed 10 kg. It is not advisable to spread it on the soil surface and distribute the fertilizer evenly throughout the tillage layer. The point should be more than 10 cm from the roots of the crop. At present, there are more compound or mixed granular fertilizers, some of which contain about 15% of nitrogen, phosphorus and potassium, and some of them are 10%, etc., so-called NPK ternary compound fertilizer. This fertilizer is often found in the form of granular fertilizer. Although the total nutrient content of granular fertilizers is many, most of them are changed from quick-acting to slow-acting. The granules need to be softened in the soil, and the nutrients are gradually released. This avoids the sudden high concentration of soil solution and burns the root system.
