Sustainability in agriculture is achieved with due consideration to ecological processes such as nutrient cycling, nitrogen fixation, soil regeneration and implementation of practices that are environment-friendly. Organic farming relies on using organic fertilizers like bone meal, compost and green manure for agricultural productivity. It also lays emphasis on the implementation of techniques like crop rotation and companion planting. This method of farming opposes the use of synthetic fertilizers, pesticides, genetically modified organisms, growth regulators and hormones in the farming process. Naturally occurring pesticides such as rotenone and pyrethrin are used in organic farming. Weed management in organic farms involves mulching, tillage, flame weeding, mowing and cutting. This book is a compilation of chapters that discuss the most vital concepts and emerging trends in the field of organic farming. It will serve as a reference to agriculturists, horticulturists, agro-economists, agroecologists and other experts involved in this area of study.
