Applications of Comet-Farm for Conservation Programs and Supply-Chain Analysis.

The COMET-Farm system is an integrated web-based platform, designed for quantification and assessment of whole farm greenhouse gas emissions, that uses state-of-the-art computation methods but in an environment that enables farmers (as well as ag consultants and land management agency personnel) to manage their data and produce high-quality estimates and reports of their emissions. COMET-Farm includes three estimation modules: soil and biomass related (field-based) emissions, livestock emissions and energy use.  The calculation methods implemented in COMET-Farm use the 2014 USDA Entity-scale GHG inventory guidelines.   Recent updates and improvements to the system, include a rapid management data input option and an application program interface to enable COMET-Farm to directly link with other farm management software.  Inclusion of new specialty crop systems and use of the system to help assess the sustainability of agricultural supply chains are also described.
