Usability Assessment of Kitchen Waste for Organic Liquid Fertilizer from Bangladesh

Improper disposal of kitchen waste produces unwanted microorganisms and breeds mosquitoes and flies, making the environment unhealthy. As organic matter, kitchen waste can serve as biofertilizer. This experiment was carried out to assess the feasibility of making liquid fertilizer from kitchen waste. The work aimed to manage kitchen waste to minimize its pollution and promote organic farming by converting it into liquid fertilizer to contribute to sustainable agriculture. The Randomized Complete Block Design (RCBD) was followed for this research. Kitchen wastes like vegetable peels, fruit peels, eggshells, fish and meat bones, used tea leaves, food waste, etc., were collected and fermented to get the liquid extracts. Essential plant nutrient analysis showed that it contained significant amounts of N (25000ppm), P (12.7 ppm), K (2.7ppm), S (0.05ppm), Mg (30.24ppm), Zn (5.8ppm), Cu (0.7ppm), Mn (0.7ppm), Fe (25ppm), and B (0.5ppm) encouraging the use of such liquid extract as liquid fertilizer. Making liquid fertilizer will encourage organic farming, minimize the hazard created by the wrong disposal of kitchen waste, achieve sustainable agriculture by lessening the use of synthetic fertilizer, and provide economical elements in farm technology.
