Özet

The purpose of this study was to determine the nutritional status of the Cardinal grapes that are grown in Canakkale. Leaf and soil samples were taken from 18 different vineyards to ensure a uniform sampling area. Although all of the soil samples contained suitable pH values for grapes, levels of organic matter content were found to be low. Lime (CaCO3) content was at an insufficient level in 72% of the soils at 0-30 cm depth and in 61% of the soils at 30-60 cm depth. Phosphorous (P) content was at low and medium levels in 94% of the soils. Potassium (K) was found to be insufficient in 50% of the soils. In both depths, the iron (Fe) content of 33% of soils was lower than the critical level. Manganese (Mn) content was at an insufficient level in 22% of the soils. There were no nutritional problems with respect to zinc (Zn) and copper (Cu) in the soils.
