Use of Spectral Reflectance for Sensitive Waveband Determination for Soil Contents

Abstract

In this paper we present the study of soil reflectance for organic matter content in soil based on their spectral signatures. We present the study of soil reflectance obtained from ASD Field spec spectrometer in the wavelength range 350–2500 nm. These values of reflectance are used to find the organic matter content in soil. Spectral curves of 8 soil samples are studied which are collected from Maharashtra state of India. Correlation between the spectral reflectance values of soil and the values obtained from chemical analysis in laboratory of soil contents is carried out. The predictions are carried out using the correlation coefficient. The content of soil organic matter in the soil samples is predicted for the wavelengths from 1801 to 1872 nm.
