Despite the significance uncertainty in the variables of erosion prediction models, spatial and temporal variability is seldom considered in soil conservation analyses and planning. The consequences of this simplification are misleading soil loss predictions, with consequences for the agricultural and environmental sustainability of agricultural fields. The objective of this paper was (a) to estimate the effect of spatial and temporal variability of the USLE factors on erosion prediction of a homogeneous agricultural field, in the Distrito Federal (Brazil), (b) to […]
