Simulating management effects on crop production, tile drainage, and water quality using RZWQM–DSSAT
The objective of this study was to explore if more crop-specific plant growth modules can improve simulations of crop yields, and N in tile flow under different management practices compared with a generic plant growth module. We calibrated and evaluated the Root Zone Water Quality Model (RZWQM) with the Decision Support for Agrotechnology Transfer (DSSAT v3.5) plant growth modules (RZWQM–DSSAT...
متن کاملDrainage water management for water quality protection
l and drainage has been central to the development of North America since colonial times, with the first organized drainage efforts occurring as early as the 1600s (Evans et al. 1996). Drainage has been encouraged to improve public highways, reduce public health risks, promote increased crop yield and reduced yield variability, reduce surface runoff and erosion, and increase land value. Agricul...
متن کاملwater table management effects on quantity and quality of water drains out of underground drainage
concerns about nitrate pollution in groundwater and downstream systems cause development of surface water management system to reduce losses of agricultural drainage water nitrate in subsurface drainage using subsurface irrigation from existing drainage lines, drainage water during the growing season and out of season is controlled. the overall objective of this study was to evaluate the effect...
متن کاملEvaluating and predicting agricultural management effects under tile drainage using modified APSIM
An accurate and management sensitive simulation model for tile-drained Midwestern soils is needed to optimize the use of agricultural management practices (e.g., winter cover crops) to reduce nitrate leaching without adversely affecting corn yield. Our objectives were to enhance the Agricultural Production Systems Simulator (APSIM) for tile drainage, test the modified model for several manageme...
