Drainage Management Systems
Green Aero Tech uses high-tech drones with topographical accuracy to find areas that require drainage. A web interface allows users to switch between elevation, drainage and visible maps. While the company can provide a drainage plan, a prescription map must be provided by a qualified drainage contractor. | READ MORE
When Matt Schwarz, an environmental contaminants specialist with the South Dakota Ecological Services Field Office for the U.S. Fish and Wildlife Service (USFW), noticed more and more farms installing drainage systems, he began to wonder what impact this might be having on the area’s wetlands.
The Transforming Drainage project is capitalizing on the network established during our first year with new research to advance our understanding of drainage water storage systems (e.g. controlled drainage, saturated buffers, and drainage water recycling), foundations for innovative tools, and continued outreach to stakeholders across the Midwest.
Patience is wearing thin in some communities because of water quality problems linked to the loss of crop nutrients from agricultural land and other sources. The city of Des Moines, IA, is moving ahead with a lawsuit against three of the state’s highly agricultural counties that manage drainage districts traced to high concentrations of nitrates in the Raccoon River, a major source of drinking water for the city.
In the hallways at Land Improvement Contractors of America (LICA) conventions, outside the classrooms of drainage workshops, and during informal conversations amongst contractors and vendors, the topics of RTK-GPS accuracy and plow capabilities are frequently discussed.
There are concerns about how subsurface impacts water quality, movement and distribution. In the Red River Valley – a region that includes North Dakota, Minnesota and Manitoba – landowners, along with local, state and federal government agencies, agricultural businesses and the University of Minnesota, are working together to tackle these concerns.
Tile drainage is accused of increasing downstream peak flows, causing flooding, moving soil and sediment and making it easy for nutrients to move. Imagine a tile drainage system with no surface inlets. Research has shown it does not increase downstream peak flows; flooding is not increased. The existence of tile drainage encourages infiltration, which reduces overland flow. The reduced overland flow reduces the amount of sediment (topsoil) movement. Recent research suggests there is less phosphorus movement through the tile.
The drainage system along the primary runway at Scott Air Force Base in St. Clair County, IL, was originally clay pipe and perforated corrugated metal pipe. After 50 years, much of the pipe was either leaking severely or had deteriorated to the critical point where replacement was required. Plans called for nearly six miles of large-diameter pipe to be installed, but it had to be done within a strict timeframe, because the runway could be shut down for only a specific time period.
The Agricultural Drainage Management Coalition (ADMC), Agricultural Drainage Management Systems Task Force and Dan Jaynes with the National Laboratory for Agriculture & The Environment collaborated to demonstrate and evaluate saturated buffers at field scale to reduce nitrates and phosphorus from subsurface field drainage systems.
What do you get when you put a Michigan dairy farmer and a conservationist in a car for several hours? If the dairy farmer is Blaine Baker, co-owner of Bakerlads Farm in Clayton, and the conservationist is Thomas Van Wagner, technical co-ordinator for the Lenawee Conservation District Center for Excellence Program, you get the initial designs of a livestock reservoir wetland sub-irrigation system.
The impact of gas pipeline construction on agricultural drain tile has become a hot topic in the midwestern United States.
Researchers at Agriculture and Agri-Food Canada (AAFC) have developed an innovative closed-loop water management recycling system that can offer farmers many benefits, including improved crop yields – but it may very well be another business opportunity for drainage contractors as well.
It’s a short jump to change many drainage systems into drainage subirrigation systems, says Mark Nussbaum, an area engineer at the United States Department of Agriculture - Natural Resources Conservation Service (USDA-NRCS). Add a bioreactor intended to eliminate water pollution and it equals good news for farmers and the environment.
Nitrate loss through tile drainage systems has been a water quality concern in the Midwest for many years. Reducing concentration from current values to a maximum level of 10 mg N L-1 has been adopted as a goal in many nutrient reduction plans.
Few soils will drain fast enough to allow golf to be played in comfort after a period of prolonged rain, but effective drainage techniques can make a huge difference to the speed at which water will drain away. Here are seven steps for successful fairway drainage that will keep costs down.
