On site soil C determinations were made using surface optics SOC400 portable mid infrared spectrometer. Testing was done on samples obtained field moist and after air drying under ambient conditions. Preliminary results indicate that good results can be obtained on non-ground field moist samples and air dried. The results are comparable to laboratory results.
