Vegetable field application of organic fertilizer should not be too much

Traditional agriculture advocates the use of organic fertilizers in vegetable fields. Some vegetable farmers even think that the more organic fertilizers, the better. However, according to the results of many experiments in recent years, the appropriate application of organic fertilizer can effectively control the nitrate content of vegetables, and the blind application of organic fertilizer will cause the nitrate content of vegetables to exceed the standard.
Too high a nitrate content in vegetables may cause direct harm to the human body. Therefore, the nitrate content of vegetables must be strictly controlled to ensure the safety of consumers. For example, the application rate of high-quality farmyard manure in vegetable fields should be controlled at 3,000-5,000 kg per mu, and generally should not exceed 6,000 kg.
