In Hungary two sites were selected near Lake Balaton , in the vicinity of Keszthely. Our priority was to choose private enterprises, because sustainable land use, which does not exploit resources, can be realised better in private property regime, than in common property regime. Thus we chose a small 2 ha farm a t Szentgyörgyvár for the plot scale experiment–erosion study. The farm is on a dissected, rolling sandy loess–fine sand plain, at the boundary of the humid and dry continental climate types. The average annual precipitation is 700 mm. The soil type is luvisol. The plots were designated on an even 9-10 % slope gradient.

For the farm scale demonstration–ecology survey we chose a 107 ha farm at Dióskál . The farm is situated in a hilly, sandy loess–fine sand area. The climate is temperate cool and humid with average annual precipitation of 700-750 mm. The soil type is luvisol, at some points strongly eroded luvisol and cambisol.
