Common plant-derived organic fertilizer raw materials

Straw type: common original corn straw, wheat straw, bean straw, rice straw. Contains high cellulose and lignin and other macromolecules, nitrogen, phosphorus and potassium and other nutrient content is low (except for legumes), alone with this type of material to do organic fertilizer rare, generally used to increase the organic matter of fermented materials, adjust the carbon to nitrogen ratio. This type of raw material is relatively abundant, inexpensive, but because these materials are mostly in the hands of agricultural engaged in retail households, large-scale acquisition is more difficult, and seasonal strong, year-round production needs to be stocked in advance.

Meal: there are soybean meal, cotton meal, castor meal, pepper meal, peanut meal, etc. Most of the offcuts of the agricultural processing industry, mostly for auxiliary materials. Meal as raw materials for organic fertilizer can be called high-end organic fertilizer, because it is mostly feed grade, raw material costs are higher, fermentation and decay should not be controlled.

Mushroom bran: commonly known as mushroom residue, mushroom bag, with golden needle mushroom residue, flat mushroom residue, apricot mushroom residue, etc., raw materials are mostly wine lees, corn cob, rice husk powder, wheat bran, soybean meal and with some nutrients, bran organic matter is high, rich in bacterial protein, vitamins, trace elements and growth factors, do organic fertilizer in fertility effect is better.

Sheep manure

Common animal-derived organic fertilizer raw materials

Animal manure: sheep manure, pig manure and cow manure are better raw materials for organic fertilizer. The organic matter content is high, but it is not easy to decompose due to the low fiber content. When used, it should be fully rotted and fermented, with high temperature to kill pest eggs, bacteria and weed seeds.

Animal processing waste: processing waste, even farming waste, etc. can also become raw materials for organic fertilizer. Usually the pollution-free biodegradation method is used.

Corn lees

Industrial waste

Industrial residues: wine lees, vinegar lees, cassava residues, sugar residues, furfural residues, lignin residues, ethanol residues, etc. Such raw materials have a large market, strong geographical presence, low prices, high organic matter content, and generally above 60% water content. Note the use of reconciliation of pH, heavy metals.

End of tobacco stalks: such materials organic matter, nutrients, sugars are higher, in as the main raw material of organic fertilizer products fertility effect is good, there are also inhibit the effect of miscellaneous bacteria, resistance to soil pests, the price is also relatively low.
