Abstract:
Soil water storage is important for ecosystem productivity in semiarid zone. To retain enough water is critical for the success of land reclamation and soil cover reconstruction, especially in coarse-grained materials. The objective of this presentation is to examine if textural variation could improve soil water storage. Field sites with different ecosystem productivity in a coarse-grained soil area were selected and soil texture was determined using a laser scattering method. The results showed that the ecosystem productivity was correlated to the textural variation in soil profile. Simulation indicated soil water storage as a function of time during drainage was higher in soils with textural variation. This study has important implication in land reclamation and soil cover reconstruction.
