Three mixed prairie sites at Mandan, ND were grazed heavily (0.9 ha steer-1), moderately (2.6
ha steer-1), or left ungrazed (exclosure) since 1916. These sites provided treatments to …

The high indigenous soil organic carbon content, root biomass, and microbial populations
in prairie soils provide a source of carbon dioxide (CO 2 ) that is important in the carbon …

Grasslands have an underground biomass component that serves as a carbon (C) storage
sink. Switchgrass (Panicum virgatum L.) has potential as a biofuel crop. Our objectives were …

Switchgrass (Panicum virgatum L.) is considered to be a valuable bioenergy crop with
significant potential to sequester soil organic carbon (SOC). A study was conducted to evaluate …

Temperate grassland ecosystems are an important component of the global carbon (C) cycle.
The Bowen ratio/energy balance (BREB) technique was used to measure CO 2 fluxes over …

Seasonal variability in climate within and between the major spring wheat (Triticum aestivumL.)
growing regions of the world causes large differences in plant development patterns. A …

Aim Extrapolation of tower CO 2 fluxes will be greatly facilitated if robust relationships between
flux components and remotely sensed factors are established. Long‐term measurements …

Temperate grasslands are vast terrestrial ecosystems that may be an important component
of the global carbon (C) cycle; however, annual C flux data for these grasslands are limited. …

Sustainable rangeland stewardship calls for synoptic estimates of rangeland biomass quantity
(kg dry matter ha −1 ) and quality [carbon:nitrogen (C:N) ratio]. These data are needed to …

Grazing management affects ecosystem function through impacts on soil condition. We
investigated the effects of long-term (over 70 years) grazing on soil properties and nitrous oxide (…
