High And Low Management Input Regimes Result In Similar Net Carbon Sequestration Rates In Zoysiagrass Golf Course Fairway Turf, Ross C. Braun, Dale J. Bremer Jan 2019

High And Low Management Input Regimes Result In Similar Net Carbon Sequestration Rates In Zoysiagrass Golf Course Fairway Turf, Ross C. Braun, Dale J. Bremer

Kansas Agricultural Experiment Station Research Reports

This study was conducted from 2013–2016 to determine how irrigation and N fertilization may be managed to enhance carbon (C) sequestration in turf. In this study, the annual rate of change in soil organic carbon (ΔSOC) was measured under two management regimes, a high management input regime (HMI) and low man­agement input regime (LMI), in a ‘Meyer’ zoysiagrass (Zoysia japonica Steud.) golf course fairway.

Both management regimes maintained acceptable turf quality and at least 75% green cover during both summers. In both management regimes, soil organic carbon (SOC) increased after the 3.16-yr (1154-d) period indicating that C ...


Nitrous Oxide Emissions And Carbon Sequestration In Turfgrass: Effects Of Irrigation And Nitrogen Fertilization (Year 2), R. Braun, D. Bremer Jul 2017

Nitrous Oxide Emissions And Carbon Sequestration In Turfgrass: Effects Of Irrigation And Nitrogen Fertilization (Year 2), R. Braun, D. Bremer

Kansas Agricultural Experiment Station Research Reports

This study was conducted from 2013–2016 to determine how irrigation and N fertilization may be managed to reduce N2O emissions and enhance carbon sequestration. In this study, annual nitrous oxide (N2O) emissions were greatest in urea and the least in unfertilized (no N) among treatments. During summer, the lower irrigation treatment resulted in less N2O emitted. All fertilizer and irrigation treatments maintained acceptable quality and high levels of percent green cover; however, the controlled-release fertilizer resulted in more consistent turf quality and green cover compared to urea and unfertilized. Urea fertilizer had higher ...


Using Cognitive Dissonance To Communicate With Hypocrites About Water Conservation And Climate Change, Melissa R. Taylor, Alexa J. Lamm, Lisa K. Lundy Jan 2017

Using Cognitive Dissonance To Communicate With Hypocrites About Water Conservation And Climate Change, Melissa R. Taylor, Alexa J. Lamm, Lisa K. Lundy

Journal of Applied Communications

The effects of climate change can be mitigated by altering human behavior related to water conservation; however, many who are aware of climate change are not aligning their behavior to curb the impact. This research sought to explore the relationship between citizens’ beliefs, attitudes and behaviors regarding water conservation and their knowledge and beliefs regarding climate change to guide the development of effective communication campaigns focused on water conservation. Using cognitive dissonance theory and an adapted environmental attitudes and behavior quartet, this research focused on individuals who demonstrated high levels of climate change knowledge but did not engage in positive ...


Nitrous Oxide Emissions And Carbon Sequestration In Turfgrass: Effects Of Irrigation And Nitrogen Fertilization (Year 1), R. Braun, D. Bremer, J. Fry Jan 2016

Nitrous Oxide Emissions And Carbon Sequestration In Turfgrass: Effects Of Irrigation And Nitrogen Fertilization (Year 1), R. Braun, D. Bremer, J. Fry

Kansas Agricultural Experiment Station Research Reports

In this study, annual nitrous oxide (N2O) emissions were greatest in urea and least in untreated (no N) among treatments. Differences were negligible due to irrigation treatment. Irrigation levels may be decreased further in the final year to induce slight stress on the low irrigation treatment. All fertilizer treatments maintained acceptable quality, however the controlled-release fertilizer resulted in more consistent visual quality ratings compared to urea and untreated. Urea fertilizer had higher peak fluxes after fertilization and overall annual emissions than polymer-coated N-fertilizer. Thus, controlled released N fertilizers, such as polymer-coated urea, in turfgrass systems could potentially help ...
