During the year 2000, Shri Lankeswar Barman, along with a group of co farmers of Village Karara Garhbhitor under Rangia Sub Division in District Kamrup (Rural), Assam, entered into the field of agriculture, to speak it more specifically into the field of organic agriculture with a great enthusiasm and hope. The Department of Agriculture had at that time inspired him to proceed with his aim with a scheme under Technology Mission. The group consisting of 4 number of farmers took the venture of vermicompost production.
Of course one year before his involvement with the departmental scheme under Technology Mission, Barman had constructed a vermicompost structure on his own. To begin with his new individual project for production of vermicompost, he approached the Assam Agricultural University, Jorhat and purchased 6000 pieces of earthworm (Variety: Red Wiggler- Eisenia fetida).
Since then he has been adhered to this venture with number of co-farmers of the same village.At present Barman owned three numbers of vermicompost pit.
Raw materials for preparation of such type of compost, they use, are mainly Banana plant, Water-hyacinth, cow dung, other vegetative plant parts etc. The process includes drying up of raw materials for about a week than put up into the compost pit, each of which is suitably constructed with brick wall and maintained the measurement of each pit with about 30 feet of length, 8 feet of width and 2.5 feet of height. A period of about one and a half month period is required for completion of the process up to harvesting the material as compost. Of course during the process inside materials, needs stirring now and then to decompose the material equally. A single pit can produce approximately 30 Quintals of vermicompost during one and a half month period.
