UF/IFAS study: Sweet potato crop shows promise as feed and fuel

GAINESVILLE, Fla. — As some Florida growers try to find new crops and the demand for biofuel stock increases globally, University of Florida Institute of Food and Agricultural Sciences researchers have found that sweet potato vines, usually thrown out during harvest, can serve well as livestock feed while the roots are an ideal source for biofuel.

This could be a key finding for the agriculture industry in Florida and to biofuel needs worldwide, said post-doctoral researcher Wendy Mussoline.

“The agriculture industry in Florida is looking to find new, viable crops to replace the citrus groves that have been diminished by the greening disease,” Mussoline said. “Potato farmers are also trying to find new crops that offer both biofuel alternatives as well as food and/or animal feed opportunities. They are conducting field trials on several varieties of sweet potatoes to determine if they are an economically viable crop that they can market.”

According to a newly published study by professor Ann Wilkie and Mussoline, an industrial sweet potato variety (CX-1) may do the trick.

UF/IFAS Extension shows horse owners that the grass can be greener

before and after pasture LARGE

AUGUSTINE, Fla. — When Diane Musil put in three acres of grazing pasture for her horses five years ago, she had more grass than she could mow. But over time, weeds began to take over, and bald patches appeared. The pasture was not the lush, green plot it used to be.

Unsure of how to deal with the problem, Musil decided to pull out all the weeds by hand — backbreaking work. “I hand-weeded all three acres,” she said. “It took me six weeks.”

Musil knew she needed expert help, so she signed up for the weed management seminar offered by the University of Florida Institute of Food and Agricultural Sciences Extension St. Johns County. There she learned how to properly use chemical treatments to target weeds choking out her pasture. This gave her the confidence to buy a sprayer and start applying the treatments herself.

A few weeks later, Tim Wilson, director of UF/IFAS Extension St. Johns County, stopped by to see how her pasture was progressing. Soil samples revealed that the grass was under-fertilized, so he walked Musil through the process of adding nutrients to the soil.

UF/IFAS researchers to study how to reduce carbon dioxide in ranch soil

GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences researchers hope to reduce possible pollutants emanating from soils in Florida cattle ranches by using a $710,000 federal grant to study soil microbes.

In the new study, UF/IFAS researchers will use lab and field studies to investigate how pasture management and factors such as temperature and rainfall affect soil microbes. They’ll also look for genetic markers to get a glimpse into microbial identity. Genetic markers are genes or short sequences of DNA scientists use to find other genes on a genetic map.

“The goal is to put together a model that can predict the release of greenhouse gases like carbon dioxide and nitrous oxide from soils under a climate that is expected to be warmer and experience more extreme dry and wet periods across the Southeast,” said Stefan Gerber, a UF/IFAS assistant professor in soil and water sciences and one of the investigators on the new study.

GAINESVILLE, Fla. – June is National Dairy Month and the University of Florida Institute of Food and Agricultural Sciences Dairy Unit is studying ways to get more milk and cheese to your table. But it’s no easy task to keep cows cool enough to produce in the scorching Florida sun.

That’s where researchers with the UF/IFAS Dairy Unit, in Hague, Florida come in. “It is difficult for a dairy cow in a hot environment to meet her full potential for either milk yield or fertility,” said Geoff Dahl, chair of the UF/IFAS animal sciences department. “The physiological adjustments the cow makes to prevent body temperature from rising during heat stress reduce productivity.”

This is especially true for cows in their dry period—cows in late pregnancy or who are not lactating. “These are times when we don’t milk the cows, because for six to eight weeks they don’t produce milk,” Dahl explained.

UF/IFAS researchers work to combat pasture weed

Topic(s): Agriculture, IFAS, Livestock, Research

GAINESVILLE, Fla. — According to University of Florida Institute of Food and Agricultural Sciences researchers, spiderwort is becoming more common in north Florida, where it has the potential to invade pastures and disrupt hay production.

Professors Jason Ferrell and Brent Sellers, and biological scientist Michael Durham have co-authored a new UF/IFAS Extension document (http://edis.ifas.ufl.edu/ag407) explaining how to control the weed.

Notable for its purple flowers, spiderwort is often seen on roadsides and undisturbed areas, said Ferrell. Though this plant has been in Florida for a long time, “it’s now becoming more common to see it in pasture and feedlot areas. People are starting to wonder what it is and what they need to do about it,” he said.

Cattle will not eat spiderwort. When hay is harvested, any spiderwort that gets into the bales will add extra moisture and spoil the hay, Ferrell added.

When people started calling in and asking how to get rid of spiderwort on their properties, Ferrell and Sellers set up an experiment to find out how best to control it.

They found that the most effective chemical treatment controlled spiderwort for four to six weeks, after which the plants reappeared. Though they did not discover a treatment that completely eliminated the weed, they recommend that producers use this four- to six-week period to harvest their hay.

According to Sellers, spiderwort is more of an issue in north Florida and is less common in the south.

The best way to get rid of the plant is to remove it by hand, Ferrell said. However, “that is a very difficult, tedious process,” especially when one stand of spiderwort contains hundreds of plants, he said.

As backyard poultry takes off, UF/IFAS Extension teaches residents how to care for their flocks

Topic(s): Agriculture, Extension, Families and Consumers, IFAS, Livestock

Chickens

JACKSONVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences Extension has become the go-to educational resource for Duval County residents who want to raise chickens in their own backyards.

When Jacksonville passed an ordinance in 2015 allowing hens on residential properties, city officials wanted to make sure that people understood the basics of backyard poultry before they were issued a permit, said UF/IFAS Extension Duval County agent Andy Toelle.

The city approached UF/IFAS Extension Duval County to create an educational program that would prepare prospective chicken owners. Residents must take the UF/IFAS Extension Duval County Backyard Poultry Seminar to get the certificate needed for the permit.

Toelle, UF/IFAS Extension Duval County agent Terra Freeman and UF/IFAS Extension Baker County director and poultry expert Mike Davis lead the seminar. They take pride in being the principal source of poultry education in the area. “We get calls every day about this program,” Freeman said.

GAINESVILLE, Fla. — The University of Florida Institute of Food and Agricultural Sciences is showing small cow-calf producers how using the latest reproductive research leads to larger profits.

The UF/IFAS Florida Heifer Development Program was developed by Kalyn Waters, UF/IFAS Extension Holmes County director, and Cliff Lamb, professor of animal sciences and assistant director of the UF/IFAS North Florida Research and Education Center, Marianna.

Both Lamb and Waters saw a need for a program to help ranchers improve the productivity of their herds.

GAINESVILLE, Fla. — Students in the University of Florida Institute of Food and Agricultural Sciences animal sciences department will benefit from a top-notch cattle-teaching facility in Gainesville, thanks to a $2.6 million legislative allotment this year.

That’s one of many advantages of the $3.6 million expansion to the UF/IFAS Beef Teaching Unit. The facility will house 5,000 square feet of multipurpose enclosed space and another 15,000 square feet for cattle pens and working area. The Legislature allotted $1 million toward the Beef Teaching Unit in its 2015 session. Phase 1 of the expansion is expected to be complete by August or September, while Phase 2 should be done in 2017, said Geoff Dahl, chair of the UF/IFAS animal sciences department.

Jack Payne, UF senior vice president for agriculture and natural resources, lauded the expanded Beef Teaching Unit.

“With the expansion of the UF/IFAS Beef Teaching Unit, our students, faculty and staff can learn, teach and conduct cattle research and Extension programs that are second-to-none in the nation,” Payne said. “We thank the Legislature for its allocation.”
