With a view to create awareness on organic agriculture, ensure sustainable income and meet out the own fertilizers requirements, TNBRD established vermicompost production units with a size of 10 x 3 x 3 ft at different villages in Thiruvannamalai district. And it is found that a single unit will yield 7350 kg of compost per year at 50 days intervals thus giving an additional income of Rs. 35000 per year including the sale of vermicompost, vermi worms and vermi wash.
