Therefore, the potential of using organic materials as organic fertilizers is important in the evaluation of agricultural industry wastes in plant nutrition. This experiment was carried out during the 2014-2015-2016 and 2017 growing seasons to evaluate the effects of grape marc and olive pomace organic wastes on nutrition of grapes of cv. Kalecik Karası and Narince (Vitis vinifera L.) in the experimental vineyards of Tekirdağ Viticulture Research Institute in Turkey. Grape marc and olive pomace were applied to the soil once in 2014 as industrial waste, without being processed. TF₁ and TF₂ represent control applications of without and with standard chemical fertilizer. GM₁, GM₂, GM₃, OP₁, OP_{2, OP3 applications represent 10 ton ha^-1, 20 ton ha^-1 and 40 ton ha^-1 doses of grape marc and olive pomace. Based on the data obtained, it has been concluded that the applications of grape marc and olive pomace as organic material did not cause significant reductions in the nutrient content of the grapevines compared to the traditional plant nutrition, and do not adversely affect the nutrition contents of the grapevine.} Keywords : Organic fertilizer Organic material Grape nutrition Sustainability Agricultural residues
