| Summary, etc. | The study on "Aerobic Composting of Ayurvedic Waste" was conducted at College of Horticulture, Vellanikkara during the period 2001-2003, to investigate the basic physico-chemical properties of Oushadhi waste material, standardize . formulations of enriched compost from the waste material and also to determine the effect of compost on plant and soil. . The waste material for the .study was collected from the manufacturing unit of Oushadhi pharmaceuticals l6c~d at Kuttanelloor, 8 km east of Thrissur. The factory produced nearly 1 tonne of waste per day during the manufacture of various products like Lehyam, Arishtam, Choomam, Kalkam etc. Hence the safe disposal of these wastes was a serious problem. A preliminary study was conducted to confirm the basic physico-chemical properties of the waste material for a period of 6 months by taking composite samples from the factory at an interval of 10 days. Temperature, pH, microbial count, colour, odour and consistency as well as the major nutrient contents of the waste material were analysed during the time period. Then the waste material were categorised into three substrates namely unsieved (01), 4 mm sieved (02) and 2 mm sieved (03) fractions. Then each substrate was enriched with organic and inorganic enrichers at different levels. The organic enrichers used were cowdung, poultry manure and neemcake each at 5, 10 and 15 per cent of substrate and also their mixtures. The study involved aerobic composting of enriched treatment combinations in pots of size 30 x 32 cm2. Temperature was measured daily and other parameters like pH, dehydrogenase activity and C: N ratio were monitored at 10 days interval throughout the composting process. The end phase of the bioprocessing was arrived at through indications on stabilisation of temperature, pH and the quality of material. Nutrient quality of the composted waste material was arrived at by analysing the content of N, P and K at initial and [mal stages of comp 0 sting. The best selected enriched compost was used to study the effect on plant and soil. It was field tested using amaranthus (var. Arun) near the vegetable farm of Department of Olericulture. The selected enriched compost was tried at three levels - 5, 2.5 and 1 t ha". A combination of the selected enriched compost at these three levels along with full doze and half doze of recommended NPK was also tried. For comparing the efficiency of the compost over FYM, FYM @ 5 t ha-I and FYM 5 t ha-I along with full dose of recommended NPK was also tried. An absolute control was also tried in field. The pot experiments on composting revealed that the selected enriched compost was superior in nutrient contents compared to ordinary composts. This enriched compost contained 3.25, 0.36 and 0.68 per cent N, P and K respectively. Apart from its nutrient value compost observed was odourless and fme textured near neutral pH of 6.37. The compost matured within 50 days resulting in a favourable C:N ratio of 12 at maturity. With respect to organic and inorganic enrichers, eventhough the nutrient content was' high in inorganic enrichment the time taken for attaining maturity was low in organic enricher' treatment combinations due to the high temperature registered by these treatment combinations during all periods of composting. . From the field study, it was inferred that with higher doses of selected compost, there was corresponding increase in growth and yield in test crop. However the selected compost at the highest level i.e. 5 t ha-I with full dose of recommended NPK emerged as the best treatment for economic yield return. This treatment also witnessed the increased build of available nutrient status of soil. This treatment could bring down expenditure for raising the crop without affecting the yield. The SEC application also resulted in increased nutrient availability by increasing the CEC and water holding capacity of soil. |
