Various remote sensing methods, including diffuse and contact reflectance spectroscopy (DRS and CRS, respectively) as well as proximal soil sensing (PSS), have been widely used for obtaining information about the soil properties. The influence of soil surface roughness on soil spectra obtained with a FieldSpecPro (ASD) spectroradiometer using three measurement techniques was investigated. The PSS...
This paper shows how strongly the bidirectional reflectance factor (BRF) of a harrowed soil surface collected in the field is correlated with the BRF of surface equivalents measured in the laboratory: an undisturbed sample as well as its artificial samples formed from the same soil material with furrows at different scales. The average fitting for all the studied samples with respect to their field...
