Plots were mapped in the field at a scale of 1:100. Soils on the plots were sampled
and particle size, wetted soil aggregate stability, and total organic carbon measured.
Moisture contents and bulk densities were measured monthly on most plots between
May and September. Infiltration capacity was assessed using a double ring infiltrometer,
and soil suction was measured daily on selected plots using soil tensiometer.
Standard methods were used for all analyses (see Goudie, 1992). Vegetation surveys
(canopy and ground cover) were undertaken monthly between May and September
on all plots. Any major changes on the plots were also noted at intervening intervals
and a record was kept of farmers’ management practices.
were calibrated each season. After storms the runoff volume was measured and a
well-mixed sample of suspended sediment collected, filtered in the field, dried and
weighed
