Directional character of soil surface reflectance in the visible and near-infrared range
soil surface reflectance bidirectional reflectance distribution function remote sensing
2008/11/26
The paper shows the importance of directional effects on soil reflectance in the visible and near -infrared range. It includes physical principles of surface interactions with radiation in this spectr...
Effect of aggregate size on the water content estimated with time domain reflectance (TDR)
TDR calibration aggregated soil
2008/11/24
Time domain reflectance (TDR) gives reliable estimates of the water content of structure-less soil. The effect of soil structure on the performance of TDR has received relatively little attention in c...
Reflectance spectrophotometry of bruising in potatoes. I. Ultraviolet to near infrared
Solanum tuberosum L. quality damage internal
2008/11/12
The reflectance spectra of bruised and unbruised tubers was measured with a scanning monochromator and bifurcated fibre optic light guide from 250 to 1750 nm. The spectra were converted into reflectan...
Reflectance spectrophotometry of bruising in potatoes. II. acquisition of spectra in the visible spectrum with an integrating sphere
Solanum tuberosum L. quality damage internal
2008/11/12
Diffuse reflectance spectra from 400 to 700 nm were measured with an integrating sphere from bruised and unbruised, unpeeled and peeled tubers cvs. Desiree, Pentland Dell and Record. Stepwise discrimi...
PREDICTION OF CHEMICAL COMPOSITION AND ENERGY VALUE OF GRASS SILAGE BY NEAR-INFRARED REFLECTANCE SPECTROSCOPY
net energy for lactation chemical composition NIRS
2010/12/2
One hundred and eighteen grass silage samples with known chemical composition and in vitro determined concentration of net energy for lactation (NEL) were scanned over the wavelength range from 1100 t...
