Abstract:

A study on the manurial quality of enriched organics was conducted in the research farm of CSKHPKV, Palampur (Himachal Pradesh) falling under wet temperate mid hill climatic condition for two years. Two organics namely farmyard manure and compost (prepared from locally available plant biomass comprising of clippings of Lantana camara and Eupatorium spp) were enriched with indigenous Jhamarkotra Phosphate Rock (JPR-A) containing 8.1% P in the clay lined pits of 1 m3 size. Organic materials with and without enrichment were analyzed for different parameters after 0, 45 and 90 days of decomposition and results have been interpreted on dry weight basis. Organic carbon in the rock phosphate enriched FYM decreased by 26% after 90 days of decomposition and the respective decrease in enriched compost was 26.5%. Total N content was higher in compost products. After 90 days of decomposition there was substantial increase in water soluble, citrate soluble and sodium bicarbonate extractable P in the enriched organics. Total P (1.54%) and total K (0.76%) content was higher in enriched compost compared to enriched FYM (total P: 1.36% and total K: 0.70%). The reduction in C:N ratio was 37 and 39% in enriched FYM and enriched compost, respectively, whereas reduction in C:P ratio was to the tune of 65% in enriched material. Thus, enrichment of FYM and Compost with rock phosphate enhanced the manurial value of organics with particular reference to P, in addition to other nutrient elements.
