Miguel L. CabreraProfessor
Crop and Soil Sciences
4119 Miller Plant Sciences Building
Athens, GA 30602-7272
706-542-1242
mcabrera@uga.edu

His research is focused on agronomic and environmental issues related to the application of animal manures (especially poultry litter, a mixture of poultry manure and bedding material) to cropland and pastureland as fertilizer. The application of poultry litter to land is currently the best way of recycling nutrients, but must be done in a way that protects the environment. When manures are not used properly, nutrients present in the manure can be transformed into forms that may contaminate air and waters. Some of our current projects with poultry litter evaluate the effect of management practices on nitrogen transformations and processes, such as nitrogen mineralization, ammonia volatilization, nitrification, denitrification, and transport of inorganic N in surface runoff. Research efforts are also dedicated to the evaluation of losses of phosphorus, hormones, and antibiotics in surface runoff from surface applications of broiler litter.

Tim CoolongAssociate Professor, Vegetable Production
Horticulture Department
1111 Plant Science Bldg.
Univ. of Georgia
Athens, GA 30602-7273
706-542-2471
tcoolong@uga.edu

Dr. Coolong works with organic vegetable growers in Georgia. His responsibilities cover horticultural aspects of the production all commercially grown vegetable crops. He has an extension, teaching and research appointment at the University of Georgia. His main areas of research emphasis include variety evaluation, fertility, and water management of vegetable crops. In previous research he has also looked at organic production systems for the management of insect-transmitted pathogens of cucurbits as well as organic production of peppers in minimum tillage systems. Extension priorities include working with industry in developing new recommendations for Georgia’s vegetable growers. He is the instructor for the capstone HORT 4125/6125 Organic Agricultural Systems course as well as HORT 3200 Protected and Controlled Environment Horticulture.


Dorcas FranklinAssociate Professor, Sustainable Agriculture
Crop & Soil Sciences, Miller Plant Sciences Rm 3119
University of Georgia
706-542-2449
dfrankln@uga.edu

Dory Franklin is a soil scientist working toward the development of more sustainable farming systems, healthy soil and clean water.  Over the last 20 years her participatory research in grass and crop systems has been focused on retaining and recycling nutrients in the soil with management practices for better farm success. Recently she has further focused on bio-management at several scales to improve plant nutrient density and quality.  She and her graduate students are exploring management practices such as strategic placement of farming equipage and farm inputs to lure cattle to fertilize nutrient poor portions of the pasture as well as adding bio-inoculates to improve compost carbon, nitrogen, and phosphorus ratios and plant availability of nutrients in manures.  She teaches CRSS 4010/6010 Principals of Sustainable Management  from an agroecological perspective and with an understanding of soil biology and morphology, nutrient balances and reduction of agricultural wastes.


L. Paul GuillebeauProfessor and Extension Entomology Specialist
Entomology
University of Georgia
413 Biological Sciences Building
Athens, GA 30602-2603
706-542-9031
bugman@uga.edu

Paul Guillebeau is a professor of entomology. His primary responsibilities revolve around pesticide education and pesticide risks. Organic production helps provide growers with additional pest management options that minimize pesticide risks. Many principles developed or revised in organic production could also be used by conventional growers to reduce their need for pesticides.


Dennis W. Hancock, Associate Professor and Extension Specialist
3111 Miller Plant Sciences Bldg.
University of Georgia
Athens, GA 30602
706-542-1529
dhancock@uga.edu

Dennis Hancock works with county extension agents and pasture-based livestock producers to formulate pasture, hay, and silage management plans that help them reach their goals for profitability, environment stewardship, and quality of life. Additionally, Dr. Hancock is actively engaged in a number of applied research efforts, many of which involve on-farm trials. Forage management requires, by its nature, a systems approach, including attention to soil fertility, plant physiology and productivity, animal performance, and environmental impacts. So, he works closely with faculty in many allied disciplines..
