- Abstract:
- North Jiangsu is a major grain production area in Jiangsu Province. Understanding the regional spatial variation characteristic of soil organic matter is important for agricultural production of Jiangsu Province. Taking Peixian County as the study area, the spatial variability of soil organic matter on the basis of 324 soil samples collected through the county was investigated. The results showed that: the mean value of soil organic matter content was 20.10 g/kg, and the corresponding variation coefficient was 0.42, belonging to medium level of variability. The auto-correlation distance of soil organic matter was 26 700 m. Moreover, soil organic matter contents were mainly concentrated in the three levels of 12~18, 18~24 and 24~30 g/kg and decreased regularly from east to west, closely relating to the distribution of soil types and land use patterns. It is indicated that the different region has different promotion potential of soil organic matter. It will provide reference for making agricultural management measures to Peixian County, even whole north Jiangsu.
