In the process of fermenting organic fertilizer with an organic fertilizer turning machine, a variety of raw materials are used, mainly from various fields such as agriculture, forestry, animal husbandry, and even urban life. These raw materials can be fermented and processed by an organic fertilizer turning machine to become nutrient rich organic fertilizers, which can be used to improve soil quality and promote plant growth. Here are some commonly used types of raw materials:

Agricultural sources

Crop residues: including straw, wheat straw, stems and leaves of leguminous crops such as soybeans and peas, corn cobs, potato vines, sugarcane bagasse, etc.

Green manure crops: Planting crops specifically for fertilization purposes, such as clover, rapeseed, ryegrass, etc. These crops accumulate a large amount of nutrients during their growth process.

Forestry source

Tree branches and leaves: Trimmed branches, fallen leaves, etc., especially in autumn, the large amount of dead branches and fallen leaves cut from forests and landscaping.

Sawdust and wood debris: by-products generated in the wood processing industry, such as sawdust, shavings, etc., are rich in cellulose and help increase the structural and breathable properties of organic fertilizers.

Source of Livestock Industry

Livestock and poultry manure: pig manure, cow manure, chicken manure, sheep manure, etc., contain abundant nutrients such as nitrogen, phosphorus, and potassium.

Stable manure: a mixture of bedding and excrement in animal pens, including moisture absorbing materials such as straw and sawdust in addition to feces.

Source of livelihood

Kitchen waste: vegetable peels, coffee grounds, tea leaves, eggshells, etc. These organic compounds are easy to decompose and are a good source of nitrogen.

Paper and textiles: A small amount of undyed paper, cotton and linen fabric fragments, etc., serve as a carbon source supplement to help balance the C/N ratio.

Other industrial by-products

Wine lees, vinegar lees, and molasses: by-products produced in the brewing and food processing industries, rich in organic matter, can be used as high-quality organic fertilizer raw materials.

Sludge: Sediments from primary treated domestic and industrial wastewater in sewage treatment plants, which can also be used as raw materials after appropriate treatment.

Each raw material has its specific physical and chemical properties, and may require pre-treatment before use, such as crushing, dehydration, or adding microbial agents to accelerate the fermentation process and ensure safe and harmless disposal. By scientifically combining different types of raw materials, organic fertilizers that are most suitable for the target soil and crop needs can be formulated. Reasonable control of factors such as raw material ratio, moisture content, pH value, and temperature is crucial for the quality and effectiveness of the final product during the fermentation process of organic fertilizer compost.
