Data on Conservation Practices
Since its inception, CTIC has been the go-to source for data on the adoption of conservation practices across the U.S. Though federal support of the popular crop residue management transect survey ended in 2004, scientists, policy makers and marketers have continued to tap CTIC's databases. Now, we're at the forefront of using remote sensing to bring back state, regional and national data on crop residue and cover crop management.
The Operational Tillage Information System (OpTIS) has been developed by Applied GeoSolutions and CTIC as a method for the automated use of remote sensing (satellite-based) data to monitor conservation practices in agricultural systems, including various forms of reduced tillage and the planting of winter cover crops.
Since 1982, CTIC's National Crop Residue Management Survey (CRM) has been the only survey in the U.S. designed to measure and track the type of tillage used by crop at the county level through direct observation of field conditions by on-the-ground experts at mile or half-mile intervals. Funding for the full national survey ended in 2004, though some states have continued to submit their own data since then. A searchable database is available here.
