Water transmission properties of a sandy-loam soil estimated with Beerkan runs differing by the infiltration time criterion

Abstract The Beerkan method consists of a ponded infiltration experiment from single ring inserted small depth into the soil. Fixed, volumes water are repeatedly poured to maintain quasi-zero head on soil surface. According standard run, new volume is surface when previously applied has completely infiltrated and entirely exposed air ( t criterion).
