Organic compound fertilizer

Abstract

The invention discloses an organic compound fertilizer which is prepared by mixing the following components in percentage by weight: 8%-15% of bean cakes, 6%-20% of ammonium nitrate, 8%-10% of pig manure, 10%-12% of straws, 10%-12% of the pig manure, 5%-15% of ferrous sulfate and the balance of coal ash. The organic compound fertilizer disclosed by the invention provides more nutrient elements for the growth of crops through added organics, namely the bean cakes, the pig manure, the straws, and the like, prolongs the fertilizer effect, improves the soil quality, is suitable for various acid-base soil textures by taking the coal ash as a filler and has the advantages of reasonability in element proportion and good production and income increase effect.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to an organic compound fertilizer suitable for field crops with long fertilizer effect and complete types of crop nutrient elements. Background technique [0002] With the development and popularization of scientific farming technology, farmers have higher and higher requirements for the quality of chemical fertilizers. Simple chemical fertilizers can no longer meet the needs of scientific farming. Most of the compound fertilizers currently used are compound fertilizers such as ammonium bicarbonate and ammonium nitrate. Practice has proved that the single application of these waste materials is far from meeting the needs of farmland soil for nitrogen, phosphorus and potassium, and some soil properties are not suitable for these compound fertilizers. Long-term application will cause soil hardening and reduce production. Contents of the invention [0003] Aiming at the deficiencies in the ...
