Drainage Management Systems
Scientists started to develop edge-of-field practices so that growers could keep the early planting offered by the tile drains while protecting nearby streams-and the Gulf of Mexico-from nitrate contamination.
A new regulatory approach in Minnesota, requiring farmers to install buffer strips to reduce nutrient runoff, is showing that mandating water protection methods can make a significant difference. 
Since Lake Erie's algae problems hit a record bloom in 2011, little of substance has been done to combat algae and the U.S. Environmental Protection Agency continues to push back on stiff regulation that could have a positive impact. 
Researchers from Ohio State University find that harmful algae is a threat in small ponds and lakes not just large bodies of water like Lake Erie. Large levels of toxins in small bodies of water are concerning, especially when the water is used for recreation, fishing and irrigation.
Iowa State University researchers found that saturated buffers are efficient at removing nitrogen, making it an effective and cost-efficient conservation practice that leads to cleaner water. 
Mole drains could be used in combination with surface drainage to improve soil water conditions on farms with flat, clay soils and potential sites for good subsurface drain outlets.
Andrew Wright, contracts manager for Miles Drainage based near Bury St Edmunds in Suffolk, England, shares why, when and how to mole drain, a method that boosts the efficiency of soil drainage systems. 
The size of the "Dead Zone," a hypoxic area in the Gulf of Mexico that no longer supports aquatic organisms, was reported to be below average and the fourth smallest area mapped since 1985. 
By 2020, the United States Department of Agriculture wants to improve water quality and soil health in the Chesapeake Bay, which touches Virginia and five other states as well as the District of Columbia.
Florida’s toxic algae bloom is wreaking havoc on marine life and jeopardizing the state’s trademark beaches, in an unprecedented season of destruction that experts have linked to pollution and poor environmental policies.
Drones capable of obtaining thermal infrared imagery have the potential to create effective and efficient drainage pipe mapping. 
To solve Iowa's water quality problems, more is needed than just planting row crop land to no-till and strip till.
Brian Perry, who works for Land O'Lakes Sustain program, says the growing focus on water quality and nitrates from farm fields means more regulation will come if farmers don't adopt new technology and practices for drainage.
When nanomaterials, tiny substances used in agrochemicals like pesticides and fungicides, combine with nutrient runoff, there is the potential for more toxic algae outbreaks for nearby water sources, a new study finds.
A new study shows nutrient pollution, which includes septic systems and agricultural runoff, may be increasing coral reefs' vulnerability to ocean acidification and accelerating their destruction.
