A new research center in the Mississippi Delta is tasked with studying agricultural water management to protect this critical natural resource.

STARKVILLE, Miss. -- In past decades, researchers have revealed many connections between water bodies and adjacent landscapes. Much attention has been given to how soil, water, nutrients, pollutants -- and energy, in general -- move from land to nearby water bodies in runoff.

Floating islands are increasingly popular as a way to provide attractive centerpieces in ponds while improving water quality.

From the shore, floating islands look like normal earthen islands covered in plants, but they are much more than that. They are hydroponic systems that, when fully colonized by growing plants, are essentially wetlands that float on the water’s surface and provide many of the same services as natural wetlands.

If you own one of the 160,000 ponds in Mississippi, chances are you have invested tremendous amounts of cash and time in this resource. Building a pond can cost tens of thousands of dollars, and fish stocking, liming, fertilization and weed control are not cheap either.

Salt marshes are coastal wetlands common throughout the globe and visible just about any time you drive over a bridge along the coast.
