PREDICTION OF THE WATER CONTENT AT FIELD CAPACITY FROM DISTURBED SOIL SAMPLES

Abstract In many soil databases, water content at -10 kPa was measured on disturbed soil samples. Meanwhile water content at -10 kPa is heavily influenced by soil structure, pore size distribution and bulk density.

Description
Summary:Abstract In many soil databases, water content at -10 kPa was measured on disturbed soil samples. Meanwhile water content at -10 kPa is heavily influenced by soil structure, pore size distribution and bulk density. In this paper a model is developed to preflict water content at field capacity given data obtained from disturbed soil samples. The linear mode/'predicts the reduction in water content at field capacity with'increasing bulk density and sand content The model has a good fit and was validated against an independent dataset Keywords: pedotransfer functions, available water capacity, soil hydraulic properties, water retention curve, bulk density
