What are the raw materials for organic fertilizer production

There are many types of raw materials for organic fertilizer production, which can be mainly divided into the following categories:

Agricultural Waste

• Straw: The stem of various crops harvested, such as wheat, rice, corn, etc.
• Soybean meal, cottonseed meal, etc.: by-products of oil crop processing, rich in protein and oil.
• Mushroom residue: Waste generated from the cultivation of edible mushrooms, which contains abundant organic matter and trace elements.
• Biogas residue: Solid residue after biogas fermentation, rich in organic matter and various nutrients required by plants.

livestock manure

• Chicken manure, cow manure, sheep manure, pig manure, etc.: The excrement of various livestock and poultry contains high nutrients such as nitrogen, phosphorus, and potassium.
• Stable manure: a fertilizer made by mixing and accumulating livestock manure and bedding materials, and subjecting them to microbial decomposition.

Industrial waste

• Wine lees and vinegar lees: by-products during the process of brewing wine and vinegar, containing rich organic matter and microorganisms.
• Cassava residue and sugar residue: Waste from starch industrial processing, rich in carbohydrates and a small amount of protein.
• Furfural residue: Waste generated during the production of furfural, containing high levels of organic matter.

domestic garbage

• Kitchen waste: including food waste such as leftovers, fruit peels, etc., which contain high levels of organic matter and moisture.
• Paper and sawdust: a portion of recyclable waste that can also be used as raw materials for organic fertilizers after processing.

Sewage sludge

• River sediment and sewer sediment: Sediments in urban water bodies and drainage systems, containing certain organic matter and minerals.

Other raw materials

• Peat: an organic accumulation rich in water formed by the accumulation of various plant residues from ancient times under long-term flooding conditions.
• Seafood waste, such as fish offal, razor clams, fish, shellfish offal, etc., contains high levels of protein and trace elements.
• Traditional Chinese Medicine Residue: Waste generated from the processing of plant-based traditional Chinese medicine, containing certain organic matter and medicinal ingredients.
