A survey study was initiated to determine the nutritional status of kiwifruit grown in the Ordu province in eastern part of the Karadeniz Region in Turkey. For this purpose soil and leaf samples were taken from 50 different kiwifruit orchards. Not only some soil chemical and physical properties and but also plant nutrient levels were determined and observed values were compared with their critical values and the degree of sufficiency was evaluated. According to the results, soils have medium-coarse in texture, slightyly and moderately in acid reactions, low in lime content, good in organic matter content. In general, available phosphorus, exchangable potassium, calcium and magnesium, available iron, copper, zinc and manganase contents of soil samples were sufficient. Soil has boron and nitrogen deficiency following order 26 and 22%. Kiwifruit leafs have sufficient and excess levels for boron, iron, copper, zinc and manganase, while nitrogen, phosphorus, potassium, calcium and sodium and chlorine were deficient levels following order 64, 24, 26, 100 and 84%. © 2007 Academic Journals.
