Estimating Salt Concentrations Based on Optimized Spectral Indices in Soils with Regional Heterogeneity
Soil salinity is one of the most damaging environmental problems worldwide, especially in arid and semiarid regions. The objectives of this study were to improve the inversion accuracy of soil salt content (SSC) in soils with spectral heterogeneity by using optimized spectral indices. Soil samples a...
