摘要

The native intensively grazed and degraded pastures in dry areas are initially low in soil organic matter content. Therefore, frequently cultivation and conversion of these lands to croplands might have a positive influence on soil properties including soil organic matter . This study was conducted to determine the impacts of cultivation of overgrazed pasture on selected soil organic matter components in Javanmardi Plain, west central Iran. Total Organic Carbon (TOC), Particulate Organic Carbon (POC) compounds, total nitrogen and carbohydrate fractions were measured. Two sites including a pasture overgrazed by sheep in adjacent with one pasture converted to wheat fields for more than 23 years were used. Soil samples were taken from 0-5 and 5-15 cm depths in each site. Land use change resulted in significant (p0.05) significant.
