Measurement of runoff and soil loss from two differently sized plots in a subtropical environment (Brazil)

Description :
The aim of this study was to assess the effects of plot size on runoff and soil loss in a subtropical environment near Guarapuava (Parana). Data were collected from 10 paired plots, 5 plots measuring 10m x 1m and 5 plots measuring 1m x 1m, installed in the same pedo-geomorphologic unit. Measurements were carried out from November 2008 to November 2009. During this period, 97 natural storms were registered. The results indicate that the small plots tended to have higher runoff compared to larger plots, especially during periods of greater rainfall volume, duration and intensity. The results of the small plots were comparable to the results obtained on the large plots, especially in relation to soil loss. These plots were useful for short-term assessments of soil erosion.
