Location: Vegetable Crops Research
Project Number: 5090-21220-007-037-S
Project Type: Non-Assistance Cooperative Agreement
Start Date: Aug 1, 2024
End Date: Jul 31, 2028
Objective:
Net ecosystem production (NEP), which represents the difference between carbon removed from the atmosphere by photosynthesis and carbon released to the atmosphere by soil and root respiration, will be measured in cranberry fields planted with 'Stevens', 'Sundance', 'Mullica Queen', and 'GBs' in Wisconsin. In addition, net ecosystem carbon balance, which includes NEP plus hydrological and vegetative fluxes in carbon, will be measured in cranberry fields planted with 'Stevens' in Massachusetts and Wisconsin.
Approach:
Standard approaches will be applied to measure net ecosystem production (NEP) in fields in Wisconsin. Periodic measurements NEP will be combined with continuous measurements of soil temperature, soil moisture, photosynthetically active radiation, and water table depth to develop models of NEP in real time. Annual estimates of NEP will be compared among beds planted with 'Stevens', 'Sundance', 'Mullica Queen', and 'GBs' in Wisconsin. In addition, standard approaches will be used to measure hydrologic and vegetative fluxes in Wisconsin and Massachusetts to quantify net ecosystem carbon balance for 'Stevens' beds in Massachusetts and Wisconsin. Cooperator will lead research in Massachusetts and contribute to research in Wisconsin.
