Reflectance spectroscopy can be used to nondestructively characterize materials for a wide
range of applications. In this study, visible-near infrared reflectance spectroscopy (VNIR)
was evaluated for prediction of diverse soil properties related to four different soil series of
the Entisol soil group within a single field in northern Turkey. Soil samples were collected
from 512 locations in a 25× 25m sampling grid over a 32ha (800× 400m) area. Air-dried soil
samples were scanned at 1nm resolution from 350 to 2500nm, and calibrations between soil …
