<em>Calotropis gigantea</em> is a plant grown almost everywhere and has no economic use. Leaves of <em>Calotropis gigantea</em> plants were composted with sheep dung. Composting conditions were maintained and samples were withdrawn at 30, 60 and 90 days of composting and analysed for pH, electrical conductivity, Ca²⁺, Mg²⁺, Cl^1-, total organic carbon, total nitrogen, available phosphorus and available potassium. Results show that contents of these parameters changes with time and at 90 days nutrient rich compost is obtained with decreased concentration of chloride.
