Increasing public concern in relation to health and environmental issues of organic waste leads to many solutions of waste management. Many different methods are discovered for proper waste management and disposal. Organic fractions of solid waste are treated with aerobic composting. It is one of the better treatments for organic waste. The important issue of concern here is the production of compost leachate with organic waste. In this study, to evaluate the competency of produced leachate as fertilizer and making the composting process more cost effective and environmentally friendly, liquid fertilizer prepared by Lahore Compost Company was used. Different percentages of leachate (0.2, 0.5, 1.5, 3.5, 5.5, 10.5, 15.5, and 25.5%) were prepared and germination rate of wheat was checked by evaluating its fertilizing quality compared to fertilizer. Results showed high germination and growth rate at lower concentration of leachate as compared with control and commercial fertilizer due to the presence of many suitable nutrients. This study was designed to compare the crop production efficiency of compost leachate with commercial fertilizer. It was revealed in this study that low leachate percentage give better crop production in case of wheat.
Key words: Compost, leachate, recycling, organic waste.
