  • Delmarva Saltwater Intrusion
Picture
​​Our research and extension outreach at the University of Delaware involves improving agronomic yields in an economically efficient and environmentally sustainable way. That includes basic soil fertility work, methods in precision agriculture, and dealing with saltwater intrusion and soil salinization.

Most Recent Publication: Non-linear spectral umixing for monitoring rapidly salinizing coastal landscapes
  • A new method for performing non-linear spectral unmixing using Sentinel-2.
  • Sub-pixel estimates indicate 3-fold increase in salt patch extent since 2017.
  • This method can be extended to other regions with proper input data.

Most Recent Publication: Assessing relationships of cover crop biomass and nitrogen content to multispectral imagery
  • Drone-derived NDVI, along with GDD, were strong predictors of biomass.
  • As an individual variable, normalized difference red edge index was useful for predicting biomass, total N, and C:N.
  • The digital surface model could predict N and C:N as an interaction with cover crop types.
