Unveiling the Efficiency of Psychrophillic Aporrectodea caliginosa in Deciphering the Nutrients from Dalweed and Cow Manure with Bio-Optimization of Coprolites

There is an immense demand for vermicomposting employing psychrophilic vermiculture (Aporrectodea caliginosa) management of wastes under the Himalayan ecosystem. Dalweed (weeds from world-famous urban Dal Lake) and cow manure (CM) are cheaply abundantly available bio resources in Kashmir valley. (DW), disposed heart city, ascribes unpleasant effects on tourism natural Initial substrate mixtures DW CM with different ratios (CM100, DW100, CM80:DW20, CM60:DW40, CM40:DW60 CM20:DW80) castings harvested were analyzed following parameters: pH, TOC, TN, NO3- P, K, Fe, Zn, C:N, C:P, C:S ratio. The results a 56day study revealed consistency disparity towards bio-optimization coprolites depending upon type waste residue mixture ratio used. Treatments medium to low dalweed residues (CM60:DW40 followed by CM80:DW20) found be optimum significantly primed chemical properties using A. caligenosa. showed non-linear response maximum decrease C:N 35%, C:P 38% CM100, 67% DW100. Humification ratio, humification index, percent humic acids changed across all treatments highest respective values 21.33 ± 1.05, 11.33 0.76, 47.83 0.76 CM60:DW40. Results also that earthworm population biomass increased increments 57.53% 74.88% CM60:DW40 over initial values. Moreover, number cocoons (95.67 1.17) recorded within lowest control (43.33 1.53). Dehydrogenase fluorescein diacetate activities inconsistent (64.64%) CM20:DW80 (63.54%) respectively substrates, while urease activity (74.40%) was observed CM100. highlight role caliginosa sustainable transformation insightful, beneficial, priming impacts its agronomic value.
