1 Ralph L. Amateis Virginia Tech Out of the Pits: Quantifying Soil Relations and Their Impact on Growth

2 Pinus taeda in Piedmont of Virginia Landscape Position Affecting Soil and Tree Growth

3 But there might be a way out of the pits: Soil Electrical Conductivity!

4 Soil Electrical Conductivity SEC is the ability of soil to conduct an electrical current (milliSiemens m -1 ). It is correlated with a number of soil properties that affect productivity, including soil texture, cation exchange capacity, drainage conditions, organic matter level, salinity, and even subsoil characteristics.

6 Soil EC maps often visually correspond to patterns on yield maps and can help explain yield variation

7 A Research Tool: Quantifying microsite variation! Maybe a number of others!

8 SEC…A New Horizon?
