What is melamine? Is it okay to make organic fertilizer from melamine dairy products?
Melamine has seriously impacted dairy products, and people dare not consume it. If tainted milk powder is used as fertilizer, will it be absorbed by crops and affect the human body? Melamine is a nitrogen-containing organic compound produced from urea, which is biodegradable and decomposed into urea by microorganisms without causing harm to plants.
According to the Council of Agriculture of the Executive Yuan, farmers who cultivate cash crops use milk as organic fertilizer because milk is high in nitrogen and phosphorus. They mix various plant residues, such as soybean meal and peanut meal, and ferment them into organic liquid fertilizer. Farmers use milk powder as organic fertilizer. If melamine is contained in milk powder, it will not be absorbed by plants. Please rest assured.
Cai Jingqiang, deputy director of the Agriculture and Food Administration, said that farmers use milk powder as organic fertilizer, even if it contains melamine, because of its large molecular weight, it cannot pass through the "membrane pores" of plant root hair cells. Therefore, melamine will not be absorbed by plants, and people can safely consume vegetables and fruits.
According to the Agriculture and Food Administration, melamine is a nitrogen-containing heterocyclic organic compound, containing 66% nitrogen. In soil, melamine will combine with calcium, iron and aluminum, or with other organic components to form colloidal polymers. The structure is destroyed and the toxic effect disappears.
