Alaşehir District (Manisa) Sultani Çekirdeksiz Grape Varieties Grown in Some Physical and Chemical Properties of Soils

This study was conducted to determine nutritional status of Sultani Çekirdeksiz grape varieties of grown the district of Alaşehir, which is the largest grape producing vineyard area in the Province of Manisa. The results of the soil analysis can be summarized as follows: The soil samples vary from loamy to clayey–loamy structure, of which 68% has a loamy structure. Although the pH of the soil samples varies from strongly alkaline to mild alkaline, 52% was strongly alkaline and 44% was mild alkaline, and the majority of the samples were characterized by organic matter deficiency. The salt values of the vineyard soils were not a limiting factor. In terms of total nitrogen, all samples were classified in the lower nitrogen class. Approximately 60% of the soil was calcareous, the available phosphorus was medium by 42%, and higher by 30%, very high by 20%; and the available potassium was found to be very low by 48%, low by 16%, and medium by 36%. And, available magnesium was low by 26%, medium by 34%, higher by 20%, and very high by 20%; and the available calcium was very low by 26%, low by 30%, medium by 36%, higher by 4% and very high by 4%. It was also found that available zinc was low in 66% of the samples; iron was adequate by 82% of the samples; manganese and copper were adequate in all samples. Significant relationships was found between nutrient element contents of the soil.
