Sand land fertilizes this way more efficiently

In sandy soils, organic matter content is relatively small, which is an important reason for the looseness of soil structure and easy leakage of water. Therefore, the fertilization of sandy land must pay particular attention to the application of organic fertilizer. Long-term application of organic fertilizer can improve the soil fertility traits.

Since inorganic fertilizers are easily soluble in water, inorganic fertilizers applied to sandy soils are easily lost with the flow of water. Therefore, solving the loss of water and fertilizer in sandy soils is the key to applying inorganic fertilizers.

Due to its own characteristics, nitrogen fertilizer is the most easily lost fertilizer. In the application of nitrogen fertilizer in sandy soil, only a small part is absorbed and utilized by crops. Most of them use the water to penetrate into the deep layer of the soil and lose their nutritional value. Therefore, nitrogen fertilizer is most suitable to use "eat less food" approach.

Although the loss of potash fertilizer is not as much as nitrogen fertilizer, the use of potash fertilizer in sandy soil can not be ignored. When topdressing, potassium fertilizer with high availability is used 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, both to avoid excessive loss of nutrients and to improve soil properties.

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 part of the nutrients. The microorganisms in the soil can slowly decompose and release the fixed phosphorus element for vegetable absorption. At the same time, it has good soil improvement effect. .
