This research was carried out on 100 soil samples collected from 0-60 cm depths from 100 vineyards in
20 rural settlements in order to determine the general characteristics of the soils where grape production is made
in the Alaşehir district of Manisa, which has the largest vineyard areas. With this research, the soil pH, EC,
organic matter, textural classes, macro and micro nutrients of Manisa vineyard were determined. Results of the
analysis of soil samples related to research area were compared with the limit values and fertility conditions of
soils were evaluated. According to the findings; although the pH of the vineyard soil of Manisa province samples
varies from strongly alkaline to neutral and the majority of the samples were characterized by organic matter
deficiency. The salt values of vineyard soils were not constitute limiting factor. In terms of total nitrogen, all
samples were classified in the lower nitrogen class. Approximately 48% of soil was calcareous, the available
phosphorus was low by 29% and medium by 71% and the available potassium was found to be very low by 97%
and low by 3%. Furthermore, available magnesium was very low (3%), low by 26%, medium by 27%, higher by
28%, and very high (16%); and the available calcium was very low (26%), low by 27%, medium by 34% and
higher (13%). It was also found that available zinc was low by 69% of the samples; iron content was adequate by
65% of the soil; manganese and copper were adequate in all samples. However, it was concluded that there are
important relationships among the nutrient content of the vineyard soil samples.
