Conventional farming methods have significantly increased yields but in recent times due to the increased awareness of people about health, there has been increasing demand of organically grown foods. Organic farming helps in maintaining soil health and thereby produce healthy and quality food materials. This concern has prompted an expanding enthusiasm for organic farming methods since they may diminish a portion of the negative impacts of conventional farming on the earth. Different organic farming methods have been used for many years to make agriculture and horticulture practical while preserving soil, water, energy, and organic assets. The future of agribusiness can be made increasingly economical and naturally solid by embracing some traditional organic farming methods and technologies.
