Abstract

The aim of this study is to evaluate and compare the effects of two incorporated organic soil amendments (plant and animal manure compost, and woodchip mulch) on the aggregate stability of drastically disturbed soils throughout the Lake Tahoe Basin. The soils were of granitic or volcanic origin, and disturbed by either ski run or road development. A second objective of this study is to correlate selected ultrasonic stability indices with infiltration and erosion variables of in situ rainfall simulation tests of the disturbed/amended soils. Results of comparisons between the ultrasonic aggregate stability indices and rainfall simulation variables suggest that the selected indices may be sensitive to soil susceptibility to crusting and sealing
