Crops need to prevent four fertilizers
Dehydration-type fertilizers are mainly caused by one-time application of too much chemical fertilizer, or insufficient soil moisture, and excessive concentration of fertilizer solution in the soil after fertilization, causing reverse osmosis of water in the crop cells and dehydration of crops. Smoked-type fertilizers mainly use ammonia, bicarbonate, and other fertilizers. Such fertilizers are applied at high temperatures and are prone to large amounts of ammonia, causing damage to crops. Burning seed fertilizers use too much seed fertilizer, or use superphosphate, or alkaline volatile ammonia bicarbonate and urea, lime nitrogen and other fertilizers, seed dressing often occurs, resulting in lack of seedlings. Toxic fertilizers Some fertilizers, such as lime nitrogen, are toxic fertilizers. After being applied to the soil, they must undergo a series of transformations to be absorbed by the plants. However, during the transformation process, some toxic substances will be poisoned and the crops will be damaged or killed.
