Research Project: Linking Measured Root Zone Dynamics to Atmospheric and Subsurface Fluxes

Location: Sustainable Agricultural Water Systems Research

Project Number: 2032-13220-002-010-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2021
End Date: Sep 1, 2023

Objective:
The overall objective of this research to measure root zone dynamics and relate this information to atmospheric and subsurface fluxes of water, energy, carbon, and nitrogen at vine and tree orchard field sites.

Approach:
Root zone dynamics play a controlling role in plant and soil health, carbon sequestration, and atmospheric and subsurface fluxes of water, energy, carbon, and nitrogen. Field studies will be initiated to thoroughly measure and mathematically model water, temperature, carbon, and nitrogen dynamics in the root zone of vine and tree orchard crops. Collaborators will measure atmospheric and subsurface fluxes of water, energy, carbon, and nitrogen at these same field sites. Measured root zone dynamics will be related to atmospheric and subsurface fluxes as part of this research in an effort to improved understanding and model predictions.
