Topsoil Stripping in Potentially Arable Forested Luvisols: A Literature Review

open access: yesEducation and Research Archive, 1990
The objective of this literature review was to evaluate the available information on the effects of stripping versus not stripping topsoil during pipeline construction in potentially arable Luvisolic soils in forested areas. A profile description representative of an undisturbed Luvisol under native forest vegetation was studied to identify potential ...
