Macropore flow estimations under no-till and till systems

Auteur(s) et Affiliation(s)



Description :
The processes associated with water movement through silt loam soils involve both the flow through macropores as preferential flow or macropore flow and flow through the micropore as matrix flow. The aim of this work was to separate the water reaching a subsurface drain during rainfall simulation into its matrix porosity and macroporosity components under different tillage conditions, using the assumption of a dual porosity model. Results of an experiment conducted in the Mississippi Agricultural and Forestry Experiment Station at Holly Springs and discussion.
