Description :
The objective of this study is to estimate the impact of different land-use types (natural secondary forest, man-made forest, grassland and cropland) on plant available N pool (inorganic N and microbial N), soil C stocks (organic C and microbial C), potential net N-mineralization, net nitrification, and urea transformations rates. This was done to provide basic data in quantitative understanding of environment and agricultural implications of land-use shift from forest or grasslands to croplands. The study sites are located in Weichang, eastern part of Hebei Bashang plateau and the south band of Inner Mongolia.
