Phosphocompost and Vermicompost

Phosphocompost: To enrich the compost with phosphorus, an insoluble source of phosphorus is added to the compost. During the composting process, the microbial activity solubilizes the phosphorus and enriches the compost. Phospho- compost contains 1.5-2.0% N, 2.0-3.0% P with C: N ratio 16-18.Phospho-compost is prepared in kuccha or reinforced cement concrete (RCC) structure where the composting process is carried out. Waste material like FYM, poultry manure, pig manure, or goat manure is dumped in the structure and mixed properly with rock phosphate. Simply, rock phosphate + raw animal waste + water is used to prepare enriched phospho-compost. Generally, in this process, rock phosphate is used @ 5 to 10% depending upon the availability. 

Vermicompost: Vermicompost is an excellent, nutrient-rich organic fertilizer and soil conditioner that is made through the decomposition of organic residues and animal dung in presence of certain species of earthworm. The vermicompost is not only enriched by nutrient from decomposition but also the activities of microflora in the gut of earthworm add mucus, hormones, enzymes which help in promoting the growth of the plants. The average nutrient content of vermicompost is 0.6–1.2% N, 0.13–0.22% P2O5, 0.4–0.7% K2O, 0.4% CaO, and 0.15% MgO. One vermiculture unit (12 m x 4 m x 2 m) having three numbers of vermibeds can produce about 3 tons of vermicompost, from which a net profit of Rs. 18300/- may be obtained in 100 days.
