Abstract:Minimal research has been conducted relating apparent electrical conductivity (ECa) surveys to plant and terrain properties in agroforestry systems. Objectives were to identify i) ECa survey relationships with forage yield, tree growth, and terrain attribute within ECa-derived soil management zones (SMZs) and ii) terrain attributes that drive ECa variability within a 20-year-old, 4.25-ha, agroforestry system in the Ozark Highlands of northwest Arkansas. The average of 12 monthly perpendicular (PRP) and horizon… Show more
