What are the main raw material for liquid fertilizer

other raw material used for liquid fertilizer manufacturing

In addition to the two common raw materials mentioned earlier, producers can also use three other raw materials for liquid fertilizer production.

• Fish Waste and Seafood By-Products
  Fish waste, including fish scraps and processing residues, contains nitơ, phosphorus, and trace elements. You also can produce organic liquid fertilizer from fish residue. After crushing and enzymatic hydrolysis, the liquid extract can be fermented or blended to produce fish-based liquid fertilizer. This process helps recover valuable nutrients while minimizing environmental pollution.

• Crop Residues and Plant Extracts
  Straw extracts, vegetable residues, and other plant by-products are rich in potassium and micronutrients. Liquid extraction or enzymatic processing releases soluble nutrients, making them suitable for blending into NPK or organic liquid fertilizers.

• Biogas Slurry and Food Processing Wastewater
  Biogas slurry and organic wastewater contain nitrogen, phosphorus, and organic acids. Using anaerobic fermentation, these materials can be converted into stable, nutrient-rich liquid fertilizer while enhancing microbial activity.
