How to apply organic fertilizer to grow pollution-free vegetables? Please give guidance on growing vegetables because the concentration of nitrogen in the soil and the type of nitrogen applied directly affect the disease resistance, marketability and nitrate content of crops. Therefore, keeping the soil loose and fertile is the key measure to reduce diseases and insect pests and obtain high quality and high yield. With the long-term application of inorganic fertilizer in vegetable fields, the soil is seriously short of organic phosphorus and potassium, soil nutrients are out of balance, a large number of acid roots remain in the soil, resulting in soil consolidation and acidification, crop resistance decreases, diseases and insect pests increase, and the quality becomes worse. Therefore, from now on, the cultivation of pollution-free vegetables should be combined with organic fertilizer.
