For areas with seasonally shallow water tables and poorly drained soils, subsurface drainage systems are ideal for removing excess from the root zone improving soil workability, trafficability, timeliness of field operations. With increased interest in tile southern Manitoba, objective this study was to evaluate impacts on canola yield oil qualities over three growing seasons (2019-2021) Winkle...

Flooding and drought are the most damaging abiotic stresses affecting maize production in United States. To combat these stresses, subsurface tile drainage systems were used conjunction with water-level control structures for subirrigation of claypan soils. The objective this research was to develop an understanding climate drain spacing on plant population, grain moisture, yield, quality measu...

The impact of a confinement dairy operation (>2000 head) using best management practices for land application of animal wastes, on estrogenic activity (E-Screen), estrogens, and nutrients of associated surface waters and tile drain runoff were evaluated. Farm tile drain and creek samples were collected from the drainage region: above and below a municipal wastewater treatment plant located upst...

The impact of controlled drainage (CD) on the groundwater table (GWT), outflow, surface runoff, and nitrogen reduction at system scale in Wielkopolska region was analyzed this study. Based field research, mainly by monitoring GWT changes 2019–2020, DRAINMOD model calibrated validated. Hydrological soil water balance simulations were carried out with 36 9 combinations for CD free (FD), respectiv...
