Towed soil sampler OpticMapper

The Veris OpticMapper has a dual-wavelength optical sensor mounted within a specially-configured planter row unit—mapping soil underneath crop residue and dry surface soil. Soil measurements are acquired through a sapphire window on the bottom of a furrow ‘shoe’. Readings are collected once per second and matched to their GPS location. The row unit design with side depth-gauging wheels assures consistent depth—adjustable from 1 to 3 inches (2.5-7.6 cm). The OpticMapper module is typically combined with Soil EC sensing on the Mobile Sensor Platform, so variations of two critical soil properties are mapped at once—soil texture and organic matter.
