Composting is the most viable treatment for biodegradable solid waste. Numerous techniques have been developed by different agencies to carry out composting. The most common method is aerobic bin method carried out on small scale. Compost piles and windrow methods needs larger land area and are mainly carried out by industries. The total time for completion of composting depend upon the type of substrate and the methods employed. Moisture content, temperature, pH and C:N ratio are among the most important factors for carrying out composting. The present review emphasised on the estimation of time taken by different types of substrates under different methods of composting and the changes in temperature, pH and C:N ratio occurring therein.
Maize is a highly consumed staple food in developing countries and the demand is predicted to double in the coming years. Therefore, there is a need to improve production through the use of compost amendments for sustainability. The aim of this study was to examine the effect of three compost amendments (lemon peels, vegetable waste, and cooked food waste) on the germination and growth of maize (Zea mays). The results showed that the application of 17% (116 t/ha) of vegetable waste or lemon peel composts supported maximum maize growth. However, vegetable waste compost had the highest potassium content, which supported maximum root growth and biomass yield. Although the addition of 17% cooked food waste compost resulted in excess nitrogen supply, reducing its application to 7% (50t/ha) supplied the required level for maize germination.
In the present study amendment of three types of compost made from lemon peels (LP), vegetable waste (VW), and cooked food waste (CF) in garden soil was carried out. It was observed that pH in all the treatments increased from control with a maximum in LP with 22% and a minimum in CF with 10% at 270 days. The soil temperature was higher than control with a maximum increase of 52% in CF and a minimum of 20% in VW at 90 days. A maximum increase of OC has been observed in CF compost-treated soil with 106% followed by LP with 64% and 24% in VW at 90 days.TN increased from control up to 90 days with 484, 100, and 46% rise in CF, VW, and LP respectively. AP and AK also showed a very high increase rate with a maximum of 551% in CF and 703% in LP respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
