Evaluation of Sunflower Plant Residues for Organic Farming

Abstract

Chemical inputs such as hormones, drugs, and fertilizers used in the cultivation of agricultural products, which have an important place in human nutrition, affect health in a negative way. Therefore, organic fertilizers and natural manuring methods are being developed today that meet the needs of plants and do not adversely affect human health, instead of chemical substances damaging the soil and plant. Organic agriculture is important in terms of health nutrition, assessment of all kinds of organic wastes that will increase soil fertility and sustainability in agriculture. Especially in all parts of the sunflower plant, there are 63.9% potassium (K2O), 21.7% nitrogen (N) and 14.4% phosphorus (P2O5) nutrients and the specific amount of stalks and roots remaining after the harvest in sunflower cultivation areas is mixed with soil and used as green manure Is one of the most important methods that can be practically applied. In addition, remaining parts of sunflower such as stem and table after harvest can be evaluated as burning. These ashes containing highly potassium can be evaluated as organic fertilizer by sprinkling on the field. In this compilation; Especially in Turkey, sunflower harvest residues are evaluated in the poor lands in terms of organic matter, raising the awareness of the farmers towards obtaining the organic products, and the contributions of this to the economy are examined.
