Document Description
Soil health is one of the primary concerns in pome fruit orchards. Compost tea applications have been shown to increase the number of beneficial microorganisms in soil and increase available nutrients. However, little is known about the lasting effects of actively aerated compost tea on soil carbon sequestration or GHG emissions. At Gabriel Farm, we will establish treatment and control orchard blocks. Current orchard floor management will be adjusted to test the efficacy of actively aerated compost tea applications on soil health, soil water holding capacity, carbon sequestration, and the exchange of GHG and water vapor between the orchard floor and the atmosphere. This project will evaluate 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 treatment and control fields.
