Assessing mitigation of phosphorus (P) leaching from subsurface drainage systems is challenging due to high spatial and temporal variation in leaching. Mean measured total P leaching from a clayey soil in an eight-year study period (four replicates per treatment) was (kg ha-1 year-1): 1.21 from shallow autumn tillage (ShT), 0.84 from unfertilised fallow (UF), 0.81 from conventional autumn ploug...

Agricultural land drainage is an instrument for growing production and a tool the conservation of resources. The performance systems thus critical achieving sustainable agricultural Recently, many types software have been developed in this field modeling simulating these systems. SISDRENA simulation model underground main objectives paper are to simulate different combination depths spaces betw...

Abstract Water table management through controlled tile drainage and subsurface irrigation (CDSI), retrofitting to conventional drainage, has been developed abate the environmental impacts of meanwhile supporting agroecosystems crop productivity. Since profile new technologies is a prerequisite understanding their socio-economic benefits, life cycle assessment was conducted assess CDSI on corn ...

Four experiments in alluvial drainage basin evolution were carried out in the Rainfall Erosion Facility (REF) at Colorado State University to investigate the dependence of basin evolution on initial topography. Basins were initially undissected. Each experiment began with a unique initial condition representing various end-members of relief and hypsometry. Drainage network development, hillslop...
