The interaction between soil moisture and root growth is an important ecological function. Soil moisture’s influence on root growth on steep slopes is essential to restoration of impacted areas. Soil moisture at various slope positions can be different which in turn can affect root growth. Plots were established at 3 steep slopes of reclaimed mine sites in Northeastern Tennessee. These plots were planted with various combinations of ground cover and tree species. Soil moisture and root growth were measured from sampling stations installed 1 foot below Northern red oaks (Quercus rubra) at 3 slope positions (upper, middle, lower) in the middle of each plot.
Results/Conclusions
Soil moisture was significantly different in the first 6 inches of soil at the middle and lower positions. Soil moisture at depths of 9-30 inches did not differ between slope positions. The first growing season did not yield much root growth. However root growth will be monitored as vegetation develops.
