Remote Sensing Applications in Mapping Salt Affected Soils

Abstract

The aim of this review paper is to provide a comprehensive overview of remote sensing-based mapping of salt affected soils. By providing multispectral and multi-temporal low cost data at various resolutions, remote sensing plays an important role for identifying and mapping the distribution of salt affected soils. Different bands of the multispectral data and the indices and transforms derived from them have been found useful in delineating salt affected soils. The various approaches to map salt affected soils involving remote sensing data, from visual interpretation to supervised and unsupervised classifications have been discussed. Quantitative mapping of soil salinity with remote sensing and other environmental variables have also been discussed.

A Study under Sodic Soil Condition for Estimation of Correlation and Path Coefficient Analysis of Rice (Oryza sativa L.) Yield and Its Component Traits

“…As a result, rice breeders are working to create cultivars with higher yields and other desirable agronomic characteristics. According to Kumar et al [2]. SAS (salt affected area) estimates in India range from 0.68 to 26.1 million hectares, depending on the methods and definitions used by various organizations across the country.…”
