Groups Visit SWFREC
Mother Nature delivered a dreary day December 15, when we hosted the SWFREC
Fall Vegetable Field Day. Still, nearly thirty participants attended the event.
Plant p'.ri. .1..;. r Dr. Pam Roberts distributed information about two trials: control of
foliar diseases on watermelon with foliar sprays, which was conducted last spring, and pj-...i .,,
Watermelon Vine Decline, which was conducted in the fall.
In-field demonstrations included Dr. Sanjay Shukla, water resources scientist, who
provided background information on the lysimeter project and explained how the large tanks monitor
water input and determine how much water is actually used by watermelon and pepper plants. In addi-
tion, Shukla and senior biological scientist Karen Armbrester discussed a slow-release fertilizer project on
tomato that is overseen by vegetable horticulturalist

"It's hard to pinpoint one particular thing (about how such field days help)," says Sam Hipp with Produc-
tion Soils LLC. "I always learn *..'ci. rl, ';. You want to keep up with what's being tested and what's
being done scientifically."
With the festive season fully upon us, we want to wish all of our clientele and their families happy holi-
days and a prosperous new year.

Science Teachers, Collier Leaders Tour SWFREC
The SWFREC hosted numerous visitors in November when two groups
included the center as a stop on their agricultural tours.
Fifteen science teachers from throughout the state comprised the Agris-
cience Education Leadership Program,
which is sponsored by the Florida Depart-
ment of Agriculture and Consumer Ser- du ate .,h ..... i. I., ,. ,. I..
vices. The group travels the state to learn
more about agriculture, and the SWFREC ., ,e.., i I
was part of the group's south Florida trip. ...
Following a welcome from associate center director Dr. John Dunckelman, the group learned about
the citrus budwood program. The Department of Plant Industry's Mark Terrell was on hand to dem-
onstrate the grafting of budwood onto an existing tree. Dr. Sanjay Shukla, water resources scientist,
gave the teachers an up-close look at lysimeters, in-field tanks that monitor how much water comes in,
how much is lost through the sandy soil, and how much of it is taken up by the crops. And Dr. Kent
Cushman, vegetable horticulturalist, educated the group about slow-release fertilizers he currently is
testing on a tomato crop.

BMP Manuals Available
Best Management Practice (BMP) manuals are now available for citrus, vegetable, and container nurs-
Participation in these grower-driven programs is voluntary; however,
growers who participate will see numerous benefits, including a poten-
tial reduction in input costs, a presumption of compliance with state
water quality standards, and a waiver of liability for recovery of costs
associated with remediation of polluted areas.
In addition, growers who participate in the citrus BMP program are
eligible for cost-share funds through the Florida Department of Agri-
Sf culture and Consumer Services. Cost-share funds for the vegetable
BMP program should be available in six months.
To obtain a free BMP information brochure and BMP manuals for citrus, vegetables, and container
nurseries, contact Chambal Pandey, senior engineer, BMP Implementation Team, at the SWFREC
