HSN Code: 31010099
Vermicompost specifications define its quality, requiring a dark brown/black color, earthy smell, crumbly texture, and specific nutrient levels (e.g., 1-2% N, 0.5-1.5% P, 0.5-1% K), low moisture (under 25%), pH around neutral (6.5-7.5), and absence of pathogens/weed seeds, improving soil structure and plant growth with beneficial microbes and growth hormones like auxins. Key quality parameters include Physical (color, odor, texture, particle size), Chemical (pH, Organic Carbon, NPK content, micronutrients), and Biological (microbial load, hormones).
