Jan 11, 2018

Chemical fertilizers referred to as fertilizer. Fertilizers containing one or more of the nutrients needed for the growth of crops made chemically and / or physically. Also known as inorganic fertilizers, including nitrogen, phosphate, potassium, trace fertilizers, compound fertilizers and so on.

They have the following common features: simple ingredients, high nutrient content; fertilizer fast, fat Meng Meng; some fertilizers have acid-base reaction; generally does not contain organic matter, no soil fertility. There are more types of chemical fertilizers, and the nature and application methods are quite different.

Chemical fertilizers containing one or more nutrients needed for the growth of crops. Short for chemical fertilizers. Fertilizers that contain only one element of nutrients that can be labeled are called unit fertilizers, such as nitrogen, phosphate, potash and secondary and macroelement fertilizers. Contains nitrogen, phosphorus and potassium three kinds of nutrients in two or three and can indicate the content of fertilizers, known as the compound fertilizer or compost. The solubility of the active ingredients of fertilizers in water is often the standard measure of the effectiveness of fertilizers. Grade is the main indicator of fertilizer quality, which refers to the percentage of effective nutrients or oxides in fertilizer products, such as nitrogen, phosphorus, potassium, calcium, sodium, manganese, sulfur, boron, copper, iron, molybdenum, zinc Of the percentage.

Phosphate fertilizer, nitrogen fertilizer, potassium fertilizer is a larger plant chemical fertilizers.

Nitrogen, phosphorus and potassium, which are constant nutrient elements in soil, usually can not meet the needs of crop growth. They need to be supplemented with nitrogen, phosphorus and potassium fertilizers. The trace nutrients in the soil chlorine is not lacking, while several other nutrients need to use trace element fertilizer. Fertilizers are mostly inorganic compounds, only urea [CO (NH2) 2] is an organic compound. Where only contains a nutrient content of the labeled fertilizers known as unit fertilizers, such as nitrogen, phosphate, potassium and so on. Where contains three kinds of nitrogen, phosphorus and potassium nutrients in two or more and can be marked with the content of fertilizer known as the compound fertilizer or compost. Quality is the main indicator of fertilizer quality. It refers to the percentage of active nutrients or their oxides in a fertilizer product.
