Reducing phosphorus loss in tile water with managed drainage in a claypan soil.
Installing subsurface tile drain systems in poorly drained claypan soils to improve corn ( L.) yields could potentially increase environmental phosphorus (P) loss through the tile drainage system. The objectives of the study were to quantify the average concentration and loss of ortho-P in tile drain water from a claypan soil and to determine whether managed subsurface drainage (MD) could reduc...
متن کاملUtilization of Polymer-coated Urea Fertilizer and Managed Subsurface Drainage Systems to Improve N Management and Corn Yields
Agronomic production on poorly drained soils in humid regions, such as the Central Claypan Region (MLRA), can exhibit low crop production in moderate to wet growing seasons. Extended periods of saturated soil conditions during a growing season may severely lower crop production by inhibiting plant growth, increasing the chance of disease, and providing conditions ideal for nutrient loss. Traffi...
متن کاملIntegrated Water and Nitrogen Fertilizer Management Using Modeling of System Dynamics Approach in Sugarcane Farmlands with Subsurface Drainage Systems
Using water and fertilizer management at the farm level can be increased water use efficiency and reduce the volume of drainage water, fertilizer losses, and other pollutants in farmland with deep underground drains such as Khuzestan agro-industrial Companies. In the present study, a comprehensive simulation model for the water cycle and the nitrogen dynamics modeling was used for water and fer...
متن کاملWater Quality in Walnut Creek Watershed: Nitrate-Nitrogen in Soils, Subsurface Drainage Water, and Shallow Groundwater
Nonpoint source contamination of surface and groundwater resources with nitrate-N (NO3-N) has been linked to agriculture across the midwestern USA. A 4-yr study was conducted to assess the extent of NO3-N leaching in a central Iowa field. Water flow rate was monitored continuously and data were stored on an internal datalogger. Water samples for chemical analysis were collected weekly provided ...
