Bio-organic Fertilizer Production Line: Raw Material Selection and Fermentation Key Points
The core of bio-organic fertilizer lies in “organic matter + functional bacteria.” Therefore, there are two basic thresholds for raw material selection: organic matter content and restrictions on harmful substances. Suitable organic raw materials include livestock and poultry manure (chicken manure, cow manure, pig manure, sheep manure), agricultural straw (corn stalks, wheat stalks, soybean stalks), agricultural product processing by-products (soybean meal, rapeseed meal, tea residue, traditional Chinese medicine residue), and food industry waste (distillers’ grains, vinegar residue, sugar residue).
