Resumen
Descripción
The notion that highly erodible soils are uniformly unproductive is not supported by empirical evidence. Thus, the presumption that the cost of conservation programs targeted at highly erodible land will be low is erroneous. Average net crop revenue on nonirrigated highly erodible cropland is less than on nonerodible land, but the productivity distributions across these erodibility classes are nearly equal. Significant acreages with all but the highest productivity can be found at all levels of erodibility. Retiring highly erodible, physically marginal cropland is not synonymous with retiring less productive, economically marginal cropland.
