Abstract:
Biogas slurry is a good source of plant nutrients and can improve soil fertility and properties. These nutrients are mainly nitrogen, phosphorus and potassium (macro) and magnesium, calcium and manganese (micro) elements. The value of bio-slurry as a fertilizer depends on the nutrient contents. Two Kg. fresh manure of the farm animals namely cattle, goat, poultry and swine in 1:1 ratio viz., T1 (cattle manure), T2 (goat manure), T3 (poultry), T4 (swine manure) were used as substrate to study the manurial value of slurry obtained after anaerobic digestion. The moisture content of on fresh basis was 91.31 ± 0.09, 92.33 ± 0.04 and 90.68 ± 0.09 percent respectively. The goat slurry was having the highest dry matter content.
