Abstract

The present invention relates preparation of superior quality vermicompost from the distillation wastes of aromatic crops said method comprises drying of distillation waste for 24 to 72 hours, obtained after the distillation of herbage for 2-3 h. at 20-25lbs of steam pressure, chopping the waste into small pieces, transferring this material into compost pits containing about 7-10 cm layer of partially rotten cowdung and 400-450 earthworms (Perionyx excavatus)/m3, daily watering of the pits to keep the plant material moist and covering them with gunny bags to check the loss of humidity, reloading the pits (20-30 cm layer) with the chopped distilled waste after 30-35 days, restricting watering after complete degradation of the added material, harvesting of the dried material and shade drying the same for 4-5 days, and sieving the harvested compost to remove earthworms.
