Summary

A new composting process known as Novcom composting method is being used for on-farm production of compost at West Jalinga Tea Estate (presently largest certified organic tea estate in Assam, India). The method has been developed by Dr. P. Das Biswas, an Indian Scientist who has been associated with organic research for the last decade. Novcom compost produced under this method is being used for soil management in the garden. The composting process enables production of mature compost within a period of 21 days. Quality of Novcom compost and its post soil application effectivity in terms of soil development were studied during the period 2006-7 to 2012-13. The samples were analyzed for physicochemical properties, nutrient content, ready nutrient supplying potential, microbial status, stability, maturity and phytotoxicity status; and the values obtained for the different parameters were within the standard suggested reference range. Soil microbial population increased by 1,000 to 10,000 times, apart from significant increase recorded in case of soil organic carbon (49.4%) and soil fertility (Available-N: 13.6%, P2O5: 5.8% and K2O: 9.5%). Post soil application effectivity of Novcom compost was documented both in terms of significant soil quality development as well as yield sustenance at West Jalinga T.E. which had been applying the compost @ 3 ton/ha/year; over a period of seven years. The study revealed that Novcom composting method could serve as an alternate option for production of good quality on-farm compost in order to enable effective soil management.
