بررسی اثر شیوه‌های مختلف بهره‌برداری بر ویژگی‌های خاک بخشی از حوزه آبخیز هراز

This study was done to investigate the effects of utilization types (private, collective and council properties) on soil properties in summer Plour rangelands in Mazandaran Province. The vegetation and topographical properties of three units of exploitation are as same as each other (same slope, aspect and altitude). Soil sampling was conducted on 0-30 cm depth of the soil sampled from 15 spot within each units of exploitation. Then soil texture, percentage of organic carbon, acidity, electrical conductivity, percentage of clay, sand, silt and absorbable potassium, absorbable magnesium, absorbable phosphorus were determined in laboratory. The data were analyzed through Duncan test by SPSS software. The results showed that, in sight of soil properties, unit of exploitation Bazam- Mozak with private property shows more desirable quantities from silt, clay, Mg and K. So, it could be say in region study private property is more desirable utilization type and management.
