The increasing cost of chemical fertilizers coupled with the growing awareness of the possible hazards of chemical fertilizer on the environment motivates the interest to study the production of organic fertilizer from biodegradable waste for sustainable and environmentally friendly agricultural practices. This book focuses on the production of organic fertilizer from fruit wastes and cow dung, characterization of the produced organic fertilizer, and comparative investigation of the fertilizer with chemical fertilizer. Organic fertilizer with competitive nutrients for sustainable and environmentally friendly agricultural practices was successfully produced. I recommend this book as a reference material for researchers, students and scientists in the area of agriculture and beyond..
