Ayan A.K.; Kizilkaya R.; Cirak C.; Kevseroğlu K. (2010)Hypericum perforatum L. plants representing a total of 35 wild populations were collected from Black Sea region of Turkey at flowering stage and subsequently assayed for some heavy metal contents, namely Cu, Mn, Fe, Zn and ... -
Influence of cadmium fractions on microbiological properties in bafra plain soils
Kizilkaya R.; Aşkin T. (Taylor and Francis Ltd., 2002)In this study, soil cadmium fractions and their relationships with some microbiological properties were investigated in disturbed twenty soil samples (agricultural area) of Bafra plain in Turkey. Total Cd in the 20 soil ... -
Organic and microbial biomass carbon contents of aggregates in a toposequence of pasture soils
Aşkin T.; Kizilkaya R. (2006)The objective of this study was to determine changes in microbial biomass carbon (Cmic) and organic carbon (Corg) of soil aggregates along a pasture slope. Soil samples from 0-50 mm depth were taken from three landscape ... -
Relationship between phosphatase activity and phosphorus fractions in agricultural soils
Kizilkaya R.; Bayrakli F.; Sürücü A. (Academic Journals Inc., 2007)Soil phosphatases play a major role in the mineralization processes of organic phosphorus. The activity of soil phosphatases can be influenced by numerous factors and soil physico-chemical properties play a key role among ... -
Spatial distribution patterns of soil microbial biomass carbon within the pasture
Aşkin T.; Kizilkaya R. (University of Zagreb, 2007)Soil microbial biomass (Cmic) is the indicator of ecosystem productivity. Although Cmic represents big part of a temperate pasture ecosystem the biomass of the vegetation of the vegetation represents even bigger part, yet ... -
The spatial variability of soil dehydrogenase activity: A survey in urban soils
Kizilkaya R.; Aşkin T. (University of Zagreb, 2007)Information on soil microorganisms and their activity used to determine microbiological characteristics are very important for soil quality and productivity. Studies of enzyme activities provide information on the biochemical ... -
