THE RELATIONSHIPS BETWEEN BIOCHEMICAL ACTIVITY CHARACTERICTIES AND SOIL PROPERTIES OF HAZELNUT GROWN SOILS

Abstract

In this research, enzyme activities of soil cultivated for hazelnut in Terme and Ünye townships were determined and the relationships between the activities and some soil properties, trace elements and heavy metals were evaluated. Correlation and regression analysis showed that there was significant positive correlation between urease activity and organic carbon, nitrogen and extractable Cu; strong positive correlation between acid phosphates activity and organic matter, organic carbon and nitrogen; but negative correlation between the activities and extractable Mn content. Additionally, positive correlation was found between alkaline phosphatase activity and pH, available P, extractable Cu, Zn and Pb contents. With the exception of C/N ratio and extractable Cd content, no significant correlation was observed between ß- glikosidase activity and soil properties.
