Periods of low rainfall in the North Carolina Piedmont prevent crops like corn and soybean from reaching their yield potential. Tillage effects on infiltration and soil water storage can be determined by characterizing the Least Limiting Water Range (LLWR) for various tillage methods.  The LLWR integrates several soil physical properties to estimate available water across a range of bulk density for a given soil. This poster will summarize recent work done to characterize the LLWR for six tillage methods from a long-term (28-year) tillage study in Reidsville, NC.
