First, nitrogen fertilizer is the most easily lost fertilizer because of its own characteristics. In the more sandy soil, only a small part of the nitrogen fertilizer is absorbed and utilized by the crop. Most of the nitrogen fertilizer penetrates into the deep soil and loses water. Nutritional value. Therefore, nitrogen fertilizer is the most suitable way to use "eat less food" approach.
Second, although the loss of potash fertilizer is not as much as nitrogen fertilizer, it should not be ignored. When topdressing, it is necessary to use potash fertilizer with high availability, so as to facilitate the absorption of root system, reduce residue and loss, and avoid waste. Nitrogen fertilizers and potash fertilizers can also be blended in the soil for application, which can avoid the loss of nutrients too quickly, and can also play a role in improving the soil.
3. Phosphate fertilizers and trace elements can be combined with a large number of high-quality organic fertilizers. The increase of organic matter in the soil can retain some nutrients. The microorganisms in the soil can slowly decompose and release the fixed phosphorus element for vegetables to absorb. At the same time, it has good soil improvement. The role.
Hydrolyzable nitrogen and available potassium in sandy soils generally do not meet the standards for vegetable growth, of which hydrolyzed nitrogen is the most serious. The loss of potassium, phosphorus and trace elements is the least, mainly because phosphorus is easily fixed, but the fixed phosphorus element cannot be absorbed and used, but trace elements are originally low in content and can easily be lost if lost. . Therefore, to cultivate vegetables on sandy soil, it is necessary to master the correct fertilization method.
