| Abstract | INDEX-S AND AREA UNDER THE WATER RETENTION CURVE TO EVALUATE SOIL PHYSICAL QUALITY Intensive field-crop production can cause the physical quality of agricultural soils to decline. Reduced soil physical quality is, in turn, linked to declining crop performance and/or profitability, as well as negative environmental impacts. The objective of that work was to evaluate the index S and of the area under the water retention curves using the potential model (AUC) in the quality of a Oxisoil. Was observed that the index-S decreased with the soil depth while AUC increased; Negative correlation was observed among index-S with field capacity (FC), permanent wilting point (PWP) and available soil water to plants (AWP); positive correlation of AUC was observed with FC, PWP and AWP. |
