Climate Change Mitigation and Adaptation
Carbon Farm Planning & Implementation
Organic amendments are reported to improve soil health and reduced greenhouse gas (GHG) emissions. This project will evalaute the impacts of adding actively aerated compost tea from dairy cow manure vermicompost on soil health, GHG emissions and crop yields. Soil sampling and gas exchange sampling will be conducted to measure change in total organic carbon, bulk density, water infiltration rate, CO2, CH4 and N2O fluxes from each treament and control fields. We hypothesize that actively aerated compost tea will be measurably increasing the soil carbon pool and releasing less CO2, CH4, and N2O to the atmosphere over the life of the project than the Control.
