Research Areas

  • Soil Physics
  • Hyperspectral Sensing
  • Digital Soil Mapping
  • Water remote sensing
  • Soil Spectroscopy
We focus on soil as a key component of agricultural systems. Our research areas include water and solute transport, soil spectroscopy, hyperspectral remote sensing, water remote sensing, digital soil mapping, and contaminant hydrology.

Important contributions from our group are:

a. National-scale digital soil maps for texture, pH, organic carbon contents, water holding capacities, cation exchange capacities,and aggregate size distribution parameters
b. Spectral library for soils of selected states
c. New spectral algorithms for estimating soil and crop parameters using spectral reflectance data
d. Water quality parameter maps of the Chilika lagoon using water remote sensing approaches
e. Multspectral and hyperspectral remote sensing methods for estimating soil properties
f. Measurement and modeling of water and nutrient transport in rice soils
g. Creation of a soil tortuosity database
