Abstract

To find dissimilarities in different geographical regions, key parameters underlying any possible separation are needed. Generally, soil factors affect plant growth and plant type. The question of which soil predictive parameters affect the vegetation pattern in each ecological unit should be answered. For this reason, a study was designed to explain variations in the composition of vegetation by soil variation and to understand most effective soil characteristics on the structure and composition of the vegetation. Therefore, this study was conducted to determine whether plant distribution could be monitored through the most effective soil parameters. For this aim, plants with diverse growth pattern and life-span (herbaceous, shrub and tree) were collected from two unlike geographical regions of Turkey. Soil samples were also collected from the rhizosphere of each plant sampled and then they were analyzed for soil physical and chemical properties and soil biological properties (soil enzyme activities). The enzymes (P-glucosidase, urease, phosphomonoesterases, and arylsulphatase) that are responsible for C, N, P and S cycles were chosen. Almost all enzyme activities (except urease) are significantly correlated with each other (P<0.01 or P<0.05).
