. Prediction of subtropical storm soil losses from field plot studies. Agric. Meteorol., The relationships between annual soil loss under subtropical rainfall and cumulative erosivity parameters have previously been investigated (Elwell and Stocking, 1973a). In this study daily soil losses were recorded from expemnental field plots planted to maize on two different but common soil types. Planting densities varied from 12,350 to 37,000 plants/ha and slopes from 3 to 8(/, One bare fallow plot was included in the investigation.

The results show the significance of derived energy-intensity parameters in predicting soil losses: (a)/~730 on bare soil; (b)/z¥~ on all covered plots to nearly maximum vegetal cover; and (c) EI s on high density late season crops. Different slopes appear to have no relevance as to choice of parameter. Cover combined with varied infiltration and runoff conditions are suggested as the main determinants lbr choice of storm soil loss parameters.
