Estimativa do fator C da eups para cobertura morta de resíduos vegetais de origem urbana para as condições de São Carlos (SP, Brasil)

Abstract

In this paper the C factor of the Universal Soil Loss Equation was estimated for a mulch of yard debris, disposed on the surface of sandy red yellow latossol (Hapludox - Oxisol). The experiment was conducted at the city of Itirapina, state of São Paulo, Brazil, during the heavy rain period from January 1st to March 31st, 1996. The value of the C factor estimated for that period was 0.075. The material presented satisfactory effectiveness to control soil erosion. Further studies are needed to evaluate the combined effect of this mulch as soil erosion controlling material and organic fertilizer.
