Abstract
⺠Optical sensor with 660 and 940 nm LEDs to measure soil organic matter content (OM). ⺠Sensor evaluated with soils in the lab, reflectance and OM had R2 of 0.91. ⺠Field tests showed ratio of prediction to deviation as high as 3.56 and R2 of 0.91. ⺠Sensor comparable with NIR spectrophotometer for OM mapping pattern with R2 of 0.86.
