Traditional agriculture advocates that organic fertilizers should be used in large quantities in vegetable fields. Some vegetable farmers even think that organic fertilizers are better. However, according to the results of various experiments in recent years, it has been shown that appropriate addition of organic fertilizers can effectively control the nitrate content of vegetables, and blindly increasing organic fertilizers will result in excessive nitrate levels in vegetables.
High levels of nitrate 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 amount of high-quality farmyard fertilizers in vegetable fields should be controlled at 3,000-5,000 kilograms per acre, and generally should not exceed 6,000 kilograms.
