Water Quantity - agriculture
Breeding and genomic work - produces drought tolerant cropsConservation tillage – reduces evaporation of water from soilsPrecision agriculture - uses wireless network, GPS, aerial maps,
low pressure valves, soil moisture metersRecycling water on dairy farms, greenhouses, poultry processing plants

Golf course BMPs for water conservation – 1st in the worldSeashore paspalum grass – uses 50% less water than BermudaXeriscape landscape – uses 50% less waterBreeding drought tolerant ornamental plantsIrrigation system improvements – drip, timers, rain shut off valvesWater collection devices - cisterns, rain barrels etc.
Water Quantity – urban landscapes

Water Quality
Stream buffer & wetland studies – to reduce nonpoint source pollutionLow dissolved O2 in S. Georgia streams – naturally occurringAg P2 – practices for land application of manure & chicken litterMigration of contaminants in soilMethod to track fecal coliform and sediment source in streamsBMPs for Georgia Gardeners to reduce nonpoint source pollutionWatershed modeling

Sustainable FarmingSustainable Farming
Powered by solar, wind, biogas and biofuelsUses pest resistant &drought tolerant crops
Minimize fertilizer and pesticide useOrganic agriculture
Integrated pest managementConservation/ no till agriculture
Precision Irrigation Restores soil fertility – biochar

Pest resistant and drought tolerant ornamentals & turfgrassIntegrated pest management
BMPs for home gardeners to reduce nonpoint source pollutionRain barrels, cisterns – collect rain water
Rain gardens, swales - manage storm waterIrrigation improvements - rainfall shutoffs, drip etc.
Sustainable Gardening

Ecosystem Services
Determine value of ecosystem services - water purification, waste degradation, nutrient cycling
Assess land needed to maintain ecosystem services in Georgia
Use of buffers and wetlands to mitigate nonpoint source pollution

Integrated biorefinery – full carbon cycling – end product biochar used to restore soil fertility
Breeding and genetic modifying crops for bioenergyBiogas on dairy farmsAg waste - chicken litter, wood chips, peanut and pecan shells, etc. as feedstocks Life cycle analysis and sustainability studies.
