Saving green: UF/IFAS computer program saves nurseries water, plants and money

Topic(s): Agriculture, Conservation, Economics, Environment, Families and Consumers, IFAS, Lawn & Garden, New Technology, Research


Poinsettia. Rapid urban growth in Florida and the Southeast creates a huge demand for a wide range of container-grown ornamental plants and trees for residential and commericial landscapes.

GAINESVILLE, Fla. — A web-based irrigation system developed by researchers at the University of Florida Institute of Food and Agricultural Sciences saved 21 percent in water use without reducing growth of container-grown landscape plants, a new study shows.

While UF/IFAS scientists say a Virginia nursery is the only one utilizing the system so far, they hope similar businesses take advantage of the software, so they can reap its benefits in saved water and money. For now, scientists are interested in the irrigation needs of container-grown plants such as anise, gardenias, azaleas, junipers, roses and more.

In this photo released from the University of Florida’s Institute of Food and Agricultural Sciences, extension agent Janet Bargar checks the water flow and direction of a pop-up irrigation system at a home in Vero Beach – Friday, May 25, 2007. Bargar, a water quality expert, suggests residents check with their county extension office about local watering restrictions. She says the ideal time to water is before sunrise and that residents should check irrigation systems regularly to be sure they’re working properly and not watering the sidewalk.

GAINESVILLE, Fla. — An app developed by scientists at the University of Florida Institute of Food and Agricultural Sciences may save homeowners about 30 percent on water usage, which translates into lower utility bills, new research shows.

Kati Migliaccio, the lead designer of the irrigation app, led a study at the UF/IFAS Tropical Research and Education Center in Homestead, Florida. Through their research, scientists found the app saved 42 percent to 57 percent of the water used with time-scheduled irrigation.

Researchers working on an oyster bar survey off of the coast of Cedar Key, Florida.

GAINESVILLE, Fla. — Oysters thrive under brackish conditions, and now a University of Florida study reveals that the bivalves can actually help create the mix of fresh water and brine they crave.

While evaluating a new method of restoring degraded oyster reefs, researchers with UF’s Institute of Food and Agricultural Sciences and UF’s College of Engineering confirmed an observation that Cedar Key-area oystermen have made for years – some oyster reefs act as natural dams, impounding fresh water that flows seaward from nearby creeks and rivers.

The result: large areas of reduced-salinity water that help maintain near-shore estuarine habitats supporting oysters, sea grasses, juvenile game fish and invertebrates important to the marine food chain as well as seafood production and recreational opportunities for people.

This finding, published in a report available at http://www.projects.tnc.org/coastal, could aid ecological and fishery restoration projects along Florida’s Big Bend Coast, a largely undeveloped area bordering the Gulf of Mexico between Wakulla and Pasco counties, said project leader Peter Frederick, a professor with UF/IFAS’ Department of Wildlife Ecology and Conservation.

The Big Bend Coast is one of the nation’s few coastal areas featuring numerous oyster reefs that run parallel to shore and stand above the water’s surface at low tide. The study site, off the Levy County coast, is a chain of oyster reefs punctuated by a few openings that allow seawater to mix with fresh water that the reef holds back as it empties into the Gulf of Mexico from the Suwannee River.

“We’ve known about other ecosystem services that oyster reefs provide, like acting as breakwaters that reduce the impact of wave action on the shore,” Frederick said. “But the role of oyster reefs in modulating the salinity of water near the shore had not been demonstrated before.” (more …)

Strategies to keep pollutants out of your neighborhood storm water pond

Topic(s): Conservation, Environment, Extension, Families and Consumers, Pollution

GAINESVILLE, Fla. — Many people live in subdivisions with storm water ponds, which collect water from the neighborhood and help keep pollutants such as fertilizers, pesticides and pet waste from getting into the broader environment. Now, UF/IFAS researchers and Extension faculty have devised strategies to help homeowners limit their pollution contribution.

Before they crafted the strategies, outlined in a new Extension document, “Strategies to Encourage Adoption of Storm Water Pond Best Management Practices (BMPs) by Homeowners,” http://bit.ly/1M6SBrU,

UF/IFAS research and Extension faculty surveyed a large planned community in Manatee County, Florida. Among other things, they found that nearly half the homeowners either didn’t know what storm water runoff was or did not know where storm water runoff goes.

Paul Monaghan, an associate professor of agricultural education and communication and a co-author of the document, said the survey result is fairly typical of homeowners across Florida and elsewhere.

“They see the curb and gutter, and they think the water is going to be treated at a plant,” Monaghan said. “They don’t really know their water runs off into the storm water pond. It’s all accumulating. It matters what you do and what your neighbors do. If we can get homeowners to understand that and know it has an effect, we will be taking a step in the right direction.”

UF/IFAS study: Most homeowners can’t properly assess damage to their trees

GAINESVILLE, Fla. — The next time a storm tears up your yard, let an expert assess the damage to any trees. A study from the University of Florida Institute of Food and Agricultural Sciences shows that homeowners perceive the risk of a damaged tree differently than trained professionals.

The survey of tree experts and homeowners in the Tampa Bay area assessed the perceptions of both groups when it came to assessing tree damage, said Andrew Koeser, an assistant professor in environmental horticulture and study author.

“While there are a number of factors tied to tree risk, most respondents were fixated on tree defects,” Koeser said. “Only experienced professionals considered other pertinent factors—namely whether the tree was actually a threat to a person, vehicle or house.”

Crested floatingheart: The lovely looking lily-like plant that clogs canals

Crested floatingheart 092415 (use this one)

Please see caption below

GAINESVILLE, Fla. — While the crested floatingheart can help beautify an aquarium or a water garden, it clogs canals and slows drainage, particularly during heavy rains.

“It’s really attractive. It looks like a water lily,” said Lyn Gettys, an aquatic plant specialist at the UF/IFAS Fort Lauderdale Research and Education Center. Crested floatingheart is also easy to grow and flourishes with little effort.

Instead of freezing unwanted crested floatinghearts and bringing them to a local landfill, many homeowners toss them into canals, said Gettys, an assistant professor of agronomy with the UF Institute of Food and Agricultural Sciences.

For about a year, Gettys has been compiling data to quantify the seriousness that crested floatingheart poses for canals. Crested floatinghearts reproduce mostly by way of ramets, an asexual form of multiplying. Gettys is trying to find out how many “babies” a single plant can make. She’s particularly interested in the effects of soil type and fertilizer on the plant’s ability to reproduce.

Preliminary data show soil has no impact. But if plants are well-fertilized, one floatingheart can produce more than 100 ramets per month. If only half of the new ramets sprout and make as many of their own babies as the original plant, that’s potentially 114,000 plants in six months, Gettys said.
