Role of Growth Substances in Conservation Agriculture
نویسنده
چکیده
Conservation agriculture (CA) integrates ecological management with scientific agricultural production. CA promotes minimal disturbance of the soil by tillage (zero tillage), balanced application of chemical inputs (only as required for improved soil quality and healthy crop and animal production), and careful management of residues and wastes. CA Promotes application of fertilizers, pesticides, herbicides, and fungicides in balance with crop requirements. CA methods can improve the efficiency of input, increase farm income, improve or sustain crop yields, and protect and revitalize soil, biodiversity and the natural resource base. In short, CA methods enhance natural biological processes of the plant above and below the ground.
