The Effect Of Water Management And Ratoon Rice Cropping On Methane Emissions And Yield In Arkansas
Leavitt, M., Moreno-García, B., Reavis, C. W., Reba, M. L., Runkle, B. R.

Sustainable intensification of rice farming is crucial to meeting human food needs while reducing environmental impacts. Rice production represents 8% of all anthropogenic emissions of CH4, a potent greenhouse gas. Cultivation practices that minimize the number of days the rice fields are flooded, such as irrigation using the alternate …

Methane Emission Reductions From The Alternate Wetting And Drying Of Rice Fields Detected Using The Eddy Covariance Method
Runkle, B. R., Suvočarev, K., Reba, M. L., Reavis, C. W., Smith, S. F., Chiu, Y., Fong, B.

Rice cultivation contributes 11% of the global 308 Tg CH4 anthropogenic emissions. The alternate wetting and drying (AWD) irrigation practice can conserve water while reducing CH4 emissions through the deliberate, periodic introduction of aerobic soil conditions. This paper is the first to measure the impact of AWD on rice field …

Surface Renewal Measurements Of H, λE And Co2 Fluxes Over Two Different Agricultural Systems
Suvočarev, K., Castellví, F., Reba, M., Runkle, B.

The importance of understanding turbulent scalar exchange over agricultural landscapes motivated this study of the surface renewal (SR) method for deployment in place of or alongside eddy covariance (EC) instrumentation. High-frequency (20 Hz) scalar data were used with turbulence and similarity parameters for SR measurements of …

Delta-Flux: An Eddy Covariance Network for a Climate-Smart Lower Mississippi Basin
Benjamin R. K. Runkle, James R. Rigbyb, Michele L. Rebac, Saseendran S. Anapallid, Joydeep Bhattacharjeee, Ken W. Kraussf, Lu Liangg, Martin A. Locke, Kimberly A. Novick, Ruixiu Suid, Kosana Suvočareva and Paul M. White

Networks of remotely monitored research sites are increasingly the tool used to study regional agricultural impacts on carbon and water fluxes. However, key national networks such as the National Ecological Observatory Network and AmeriFlux lack contributions from the Lower Mississippi River Basin (LMRB), a highly productive agricultural …
