COMET-Planner is a preliminary planning tool to evaluate potential carbon sequestration and greenhouse gas emission reductions from adopting conservation practices on farm.
COMET-Planner provides meta-model results of COMET-Farm model runs at a regional level for conservation practices selected through the planning process. For these reasons, it is a good idea to begin building conservation scenarios using COMET-Planner after the landscape has been adequately surveyed both in the field and through available mapping tools. If you have not reviewed the sections on Reading the Landscape and Mapping Tools, we would recommend returning to these pages before proceeding to the planning process with the COMET-Tools.
A tutorial on how to use COMET-Planner, specifically looking at a hypothetical Carbon Farm Plan for the Allee Demonstration Farm is provided below in video. Optional: You may also view these as slide deck or PDF Version .
In the interest of time, these tutorials do not include all of the conservation practice standards included in the hypothetical CFP for the Allee Demonstration Farm. For the complete list of practices included, you can view the downloaded COMET-Planner report for this operation.
The COMET-Team would highly recommend downloading a report because:
Users are not able to save a report to an account like in COMET-Farm, so in case you need to run the tool again, you are able to see the practices you have previously entered.
COMET-Planner undergoes periodic updates based on model changes in COMET-Farm. By having a downloaded report handy, planners can document when [date] they generated a report. If a user happens to run a report later, generating different estimates, we can check the model change log.
We will refer back to this COMET-Planner report again in the Building Tables section of Module 3.
EPA's Greenhouse Gas Equivalencies Calculator converts your COMET CO2e emissions to the equivalent amount of CO2e from cars driven, fuel used, number of smart phones charged, or carbon sequestered by acres of forests in a year. This can help the reader have an understanding of the GHG significance of the CFP's implementation.
To convert COMET estimates, follow the steps below:
Step 1: Select Emissions data
Enter the CO2e from the COMET report into the first box
Step 2: select Convert Data
The page will convert your CO2e estimate on the fly into 24 different measurements. You may select which suits your needs best.
Navigate to COMET-Planner.
Using COMET-Planner, evaluate the total GHG emission reductions associated with the following Conservation Practice Implementations in Benton County, Missouri:
Intensive Till to No Till or Strip Till on Non-Irrigated Cropland (100 acres)
Replace Synthetic N Fertilizer with Compost (CN ratio 20) on Non-Irrigated Croplands (100 acres)
Answer provided in Total CO2 Equivalent for ALL practices
A. 45 tonnes CO2 equivalent per year
B. 52 tonnes CO2 equivalent per year
C. 56 tonnes CO2 equivalent per year
D. 94 tonnes CO2 equivalent per year
