Simulation Of Nitrous Oxide Emissions In Zoysia Turfgrass Using Daycent And Dndc Ecosystem Models, Mu Hong, Yao Zhang, Ross Braun, Dale J. Bremer
Kansas Agricultural Experiment Station Research Reports
Nitrous oxide (N2O) is an important greenhouse gas (GHG) implicated in global climate change. Process-based ecosystem models, such as DAYCENT and DNDC, have been widely used to predict GHG fluxes in agricultural systems. However, neither model has yet been applied to warm-season turfgrasses such as zoysiagrass. This study parameterized, calibrated, and validated the DAYCENT and DNDC models for N2O emissions from Meyer zoysiagrass (Zoysia japonicaSteud.) using Bayes’ theorem and field data from Braun and Bremer (2018a, 2019) and Lewis and Bremer (2013). Results indicated DAYCENT, but not DNDC, reasonably simulated the impacts of irrigation …

Influence Of Simulated Golf Cart Traffic And Nitrogen Rate On Buffalograss Quality, E. Alderman, J. Hoyle, J. Fry, S. Keeley
Kansas Agricultural Experiment Station Research Reports
Application of 2 and 3 lb N/1,000 ft2resulted in acceptable buffalograss quality when subjected to simulated golf cart traffic. Across all fertilizer treatments, traffic rates of 8 and 16 passes per week resulted in unacceptable quality ratings for the study duration.
