Traditional agriculture holds that vegetable fields should be heavily fertilized with organic fertilizer, and some vegetable growers even believe that the more organic fertilizer, the better. However, according to the results of many experiments carried out in various places in recent years, appropriately increasing the application of organic fertilizer can effectively control the nitrate content of vegetables, while blindly increasing the application of organic fertilizer will cause the nitrate content of vegetables to exceed the standard.

Traditional agriculture holds that vegetable fields should be heavily fertilized with organic fertilizer, and some vegetable growers even believe that the more organic fertilizer, the better. However, according to the results of many experiments carried out in various places in recent years, appropriately increasing the application of organic fertilizer can effectively control the nitrate content of vegetables, while blindly increasing the application of organic fertilizer will cause the nitrate content of vegetables to exceed the standard.
Excessively high nitrate content in vegetables may cause direct harm to human health. 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 to vegetable fields should be controlled at 3000-5000 kg per mu, and generally should not exceed 6000 kg.
