ESTIMATION OF CALCIUM CARBONATE IN ANTHROPOGENIC SOILS ON FLYSCH DEPOSITS FROM DALMATIA (CROATIA) USING VIS-NIR SPECTROSCOPY

The Effects of Soil Moisture Content on Reflectance Spectra of Soils Using UV-VIS-NIR Spectroscopy

This study was conducted to investigate the effects of soil moisture content on reflectance spectra of sandy soils with different phosphorus (P) concentrations using UV-VIS-NIR reflectance spectroscopy. Sandy soils with average particle size of 250 μm were used. Investigations were conducted at 0, 12.5, 62.5, 175, 375, 750, and 1000 mg/kg phosphorus application rates. Three soil moisture conten...

Spectral Signatures for the Lake Okeechobee Soils Using UV-VIS-NIR Spectroscopy and Predicting Phosphorus Concentrations

Abstract. Developing a phosphorus sensing system using UV, VIS and NIR provides a non-contact, cost & time effective, less laborious measurement of phosphorus (P) concentration in a soil sample. The determination of soil spectral signatures in the Lake Okeechobee basins in Florida improves the prediction accuracy of calibration models produced for the determination of soil P concentration for O...

Effects of Soil Moisture Content on Absorbance Spectra of Sandy Soils in Sensing Phosphorus Concentrations Using Uv-vis-nir Spectroscopy

This study was conducted to investigate the effects of soil moisture content on the absorbance spectra of sandy soils with different phosphorus (P) concentrations using ultraviolet (UV), visible (VIS), and near-infrared (NIR) absorbance spectroscopy. Sieve sizes were 125, 250, and 600 m for fine, medium, and coarse, respectively. The medium size of the samples was used for the study. Investigat...

Geographic classification of wines using Vis-NIR spectroscopy

Pear quality characteristics by Vis / NIR spectroscopy.

Recently, non-destructive techniques such as the Vis / NIR spectroscopy have been used to evaluate the characteristics of maturation and quality of pears. The study aims to validate the readings by the Vis / NIR spectroscopy as a non-destructive way to assess the qualitative characteristics of pear cultivars 'Williams', 'Packams' and 'Carrick', produced according to Brazilian conditions. The ex...
