Horse Racing Road Apples
Might Soon Turn a Shiny Profit

On June 9, the final horse race of the Triple Crown,
the Belmont Stakes, will run. But there'll be more than
confetti to pick up afterwards.

Horse tracks like Belmont Park produce up to 600
cubic feet of manure a day-with or without a race. Add
to that the thousands of horse farms around the country
and you have one big problem.

But researchers at the University of Florida's Institute
of Food and Agricultural Sciences (IFAS) say those road
apples may soon be marketable.

The trick is composting, a process that breaks down
organic waste into fertilizer. While a well established
practice for cow manure, composting has never been
applied to horses-for good reason.
"With horses, you're not just collecting the feces.
You have to take all the bedding and other mess that's in
a stall with the horse," said Lori Warren, a UF equine
nutritionist. "Until now, that meant dealing with a lot of
junk filler mostly wood chips or straw that landed
you with something that would barely make a decent

Consequently, horse waste was usually taken to a
dump or spread in empty fields.

"Horses have been overlooked because there just
haven't been enough of them to really matter," Warren
said. But the horse population has skyrocketed since the
late 1990s and new environmental regulations make
disposal more expensive, she added.

"In Florida, we're expecting some pretty major
restrictions to come down in the next few years," Warren
said. "So a lot of us are just trying to get a head start on
turning a negative into a positive."

Composting horse waste has been tried before.
Keenelands Racetrack, near Lexington, Ky., tried and
abandoned the process because it didn't yield viable
fertilizer. Instead, they've returned to the costly process
of shipping waste hundreds of miles to a farm where it's
used to grow mushrooms.

Butch Lehr, operations manager at Churchill Downs,
home of the Kentucky Derby, said that his racetrack
employs an operation called Equine Organic. The
company carts the waste away and composts it; however,
it has yet to develop a viable fertilizer from the waste it


A viable composting method is important because
horse waste contains large amounts of nutrients such as
phosphorous. Most are essential to fertilizer, but raw
manure releases nutrients too fast, polluting the
environment, Warren said.

With composting, bacteria digest and excrete those
nutrients as part of complex organic compounds.

"You're basically turning it into a time-release
fertilizer," said Sara Dilling, a graduate student working
with Warren. "And the heat that the bacteria produce as
they're digesting everything kills off any type of bad
bacteria that could hurt people. So you're making it safer,

At UF's Horse Education Center near Gainesville,
Dilling regularly checks eight test piles of compost for
temperature, moisture and pH to measure how different
additives affect the process. The 10-foot piles are typically
above 100 degrees Fahrenheit inside, some close to 130

"The biggest problem we have right now is time,"
Dilling said. "The compost we have would have to sit for
five months before it's anywhere near viable."

The piles are given variable amounts of water from
a computerized sprinkler system. Additives such as uric
acid are added to slow down or speed up bacterial growth.

Even different bedding types are being tried. Sawdust
would be ideal for composting, Dilling said. Wood chips
don't offer enough surface area for the bacteria and straw,

Lori Warren, an equine nutritionist, is checking the
qualities of experimental compost heaps as they are being
moved at the UF Horse Research Center north of Ocala
December, 2007. Fine tuning the c- ,,mj.. .i.i process for
horse manure may soon allow farmers to turn prolematic
waste into valuable fertilizer (AP photo/University of
Florida/IFAS/Sally Lanigan)

the most popular racetrack bedding, has a waxy coat that
protects it from digestion.

A few miles from the UF center, Lambholm South
horse farm began composting horse waste six years ago
with help from UF researchers. Today, with nearly 300
horses, the farm produces about 150 cubic yards of
fertilizer a month.
"It's still not up to the exact quality that we want,"
said Dana Camp, head of Lambholm's composting
program. "But we use it to help seed yards, and we actually
sell a fair amount of it, too. So it's starting to become that
positive that we're looking for."

To hear one of the buyers, they don't have much
further to go.

"You wouldn't want to use it for inside plants, but
for outdoor trees and bushes, I've never found anything
betterto pot them in," said Bill Swann, owner of the nearby
Nature's Pharmacy Nursery.

"From a consumer perspective, there's no doubt
there's a future for this stuff," he said. "Now we've just
got to get the horse farmers to believe in their own ...
well, dung."

SCan Rope Lasso E.

Canadian scientists have
discovered that hanging pieces of rope in feedlot cattle
pens is a fast, convenient and cheap way to detect E. coli
0157:H7 bacteria in animals before they are sent to

A study involving Alberta Agriculture and Foods
called for hanging ropes in feedlot pens the night before
cattle were slaughtered. "The ropes were used as sampling
devices," AAF scientist Margaret McFall told reporters.
"When you put something strange in a pen, the animals
are attracted to it and rub and chew on it, and the E. coli
in their mouth can be transferred to the rope."

Ropes were tested the day of slaughter for E. coli,
with fecal and hide samples taken to compare with the
rope samples. The hope is that cattle from pens that are
identified as having potentially high levels ofE. coli could
be managed differently, controlling the spread of the
