| Abstract: | Spatial patterns of soil nutrient (N and P) were examined using geostatistical analysis in three different soil horizons (A,
B, C) in a mixed forest in Beijing China. Soil nutrients (total nitrogen or TN, total phosphorous or TP, and available nitrogen
or AN) were high near the surface and lower with depth. In general, the spatial correlation in soil nutrient content varied
by depth. Soil nutrient content was also strongly influenced by vegetation type and elevation. These results consist of a
set of simple statistical models that could provide information for the planning of the forest management and long-time research
in this area. |
