Soil morphology and soil water regime of loess soils under oak in the Meerdaal forest, Belgium

Soil water content of the top layer of a soil catena of Hapludalfs and Fragiudalfs was monitored in an experimental field site under oak in the Meerdaal forest. Knowledge of the soil water regime is needed to assess soil suitability of the soils in the forest for natural regeneration of oak. The soi...

Description
Summary:Soil water content of the top layer of a soil catena of Hapludalfs and Fragiudalfs was monitored in an experimental field site under oak in the Meerdaal forest. Knowledge of the soil water regime is needed to assess soil suitability of the soils in the forest for natural regeneration of oak. The soil water content was measured during one season using time domain reflectometry. In contradiction to what was expected, the top soil in the zones of the catena with a clear fragipan in the underground is significantly and consistently drier than the top soil in the zones with a homogeneous, unconsolidated argic B horizon. This is explained by the specific morphologic features of the fragipan which are a direct result of its formation process.
