Mapping Crop Residue and Tillage Intensity on Chesapeake Bay Farmland

Submitted by Anonymous (not verified) on

Crop residues play an important role in agricultural conservation, serving as a protective layer on agricultural fields, shielding soil from wind and water, preventing erosion, reducing moisture loss, and increasing soil carbon storage. Accurate assessment of the extent of crop residue is necessary for tracking the implementation of conservation tillage practices. Traditionally, residue is assessed using in-field observations. However, these methods are not cost-effective over large land areas.
