Crop production in Georgia tends to be water limited due to climatic and soil conditions; and because of the demands for water, producers face increasingly stringent water management regulations. Georgia producers are dependent on supplemental irrigation to maintain competitive yields. Most soils in Georgia are relatively sandy, tend to be drought-prone, are susceptible to compaction and erosion, thus present water management challenges. Adverse climatic and soil conditions and potential policies restricting irrigation water use reveal a major dilemma facing Georgia producers; finding ways to maximize crop yields, maintaining responsible water-use efficiency, and limit soil and water quality concerns. In Georgia, conservation tillage systems have significant potential as a water management tool for agricultural producers. Conservation tillage systems, coupled with residue management and paratilling, increase infiltration and soil and plant available water, thus conserve soil and water resources by reducing runoff, soil loss and irrigation demand. In Georgia, conservation tillage systems improve producer profit margins, reduce environmental risks, and conserve water resources.
