Agricultural drainage increases hydrological connectivity between fields and receiving environments. Tile drains ditches are the main types studied at field scale. They can be associated with temporary surface to improve removal of water. Combining tile is likely modify runoff soil water dynamics. The behaviour tile-drained has been event scale, but few studies have conducted over a full year, ...

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...

Agriculture is a major nonpoint source of phosphorus (P) in the Midwest, but how surface runoff and tile drainage interact to affect temporal concentrations and fluxes of both dissolved and particulate P remains unclear. Our objective was to determine the dominant form of P in streams (dissolved or particulate) and identify the mode of transport of this P from fields to streams in tile-drained ...

Tile drainage belongs to one of the most important meliorative measures in Czech Republic. It has been hypothesised that it may improve some soil properties which are influenced by groundwater and their water regime. In case meadows, used management method also influence properties. this study, different physical (particle bulk density, total porosity, maximum capillary capacity, minimum air re...

Subsurface (tile) drainage, while necessary for viable agricultural crop production in the humid, poorly drained regions of world, has been linked to offsite nutrient transport, culminating harmful algal blooms and hypoxia downstream waterbodies. Drainage water management (DWM), also known as controlled promoted a method reduce nitrogen (N) phosphorus (P) loss from field scale tile drainage; ho...

The potential impact of controlled drainage (CD), which limits outflow, and subirrigation (SI), provides supplemental water through drain tile, on surface quality are not well known in the Red River Valley (RRV). In this study, samples were collected analyzed for chemical concentrations from a tile-drained field that also has modes RRV southeastern North Dakota 2012–2018. A decreasing trend ove...

A watershed's water quality is influenced by contaminant-transport pathways unique to each landscape. Accurate information on contaminant-pathways could provide a basis for mitigation through well-targeted approaches. This study determined dynamics of nitrate-N, total P, Escherichia coli, and sediment during a runoff event in Tipton Creek, Iowa. The watershed, under crop and livestock productio...

Tile systems drain water applied to agricultural fields as irrigation and precipitation but also may intercept regional groundwater flow. Identification and characterization of the potential sources of tile water is essential for informed management of salinity and contaminants. Factors influencing tile discharge including depth of water applied, evapotranspiration, water storage, drain blockag...
