We explore the information associated with soil water retention included in the large scale soil maps of Hungary. We employed factor analysis to investigate tire role of different commonly measured soil properties - namely -,and and clay content, organic matter content, pH and CaCO3 content - on determining soil water retention at different pF values (pF0, pF2.5, pF4.2 and pF6.2). Analyses were performed oil all the samples of the database, that contains 382 1 soil horizons of diverse soil types, as well as a selection of the horizons belonging to Chernozem soils of the database. Results show considerable differences of water retention characteristics of Chernozems, mainly at pF0. This suggests that a separate analysis for different soil types might be appropriate in order to characterize the impact of measured soil properties on water retention.

Abstract
We explore the information associated with soil water retention included in the large scale soil maps of Hungary. We employed factor analysis to investigate tire role of different commonly measured soil properties - namely -,and and clay content, organic matter content, pH and CaCO3 content - on determining soil water retention at different pF values (pF0, pF2.5, pF4.2 and pF6.2). Analyses were performed oil all the samples of the database, that contains 382 1 soil horizons of diverse soil types, as well as a selection of the horizons belonging to Chernozem soils of the database. Results show considerable differences of water retention characteristics of Chernozems, mainly at pF0. This suggests that a separate analysis for different soil types might be appropriate in order to characterize the impact of measured soil properties on water retention.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
