Abstract: Alfalfa hay yield, yield-consumptive use ratio (

Abstract: Sudan grass is a moderately salt-tolerant annual that is capable of substantial osmotic adjustment under high soil salinity conditions, but little is documented about its actual water use and yield under saline conditions. ...

Abstract: Subsurface drains in clay soil overlying a shallow artesian aquifer intercept water from the aquifer and the deep percolation from the root zone. Flow down the backfilled drain‐line trench is significant immediately after ...

Abstract: The performance of subsurface drains in a clay soil overlying an artesian aquifer is evaluated at a site in Imperial Valley, California. Field studies are undertaken to examine water and salt movement through the soil ...

Abstract: Reference evapotranspiration

Abstract: Infiltration into soils is affected by several factors, including the soil‐air pressure. Soil air may become compressed between a confining layer (water table) and a nearly saturated surface soil. Compressed and counterflowing ...

Abstract: Although widely used for field measurements of soil moisture, problems continue with the use of the neutron probe in clay soils comprised of over 40% clay fractions, and in the determination of the intensity of field ...

Abstract: This paper assesses the potential of the “reduced-runoff” surface irrigation method for clay soils to limit tailwater runoff and evaluate its impacts on crop production and soil salinity throughout a 3-year alfalfa hay ...

Abstract: Drainage design for water quality management in irrigated areas requires use of hydrodynamic models that delineate flow paths of subsurface water moving to drains. Use of only traditional drainage design equations for ...
