Turf grasses are ubiquitous in the urban landscape of the United States and are often associated with various types of environmental impacts, especially on water resources, yet there have been limited efforts to quantify their total surface and ecosystem functioning, such as their total impact on the continental water budget and potential net ecosystem exchange (NEE). In this study, relating turf grass area to an estimate of fractional impervious surface area, it was calculated that potentially… 
Lawns are ubiquitous in the American urban landscapes. However, little is known about their impact on the carbon and water cycles at the national level. The limited information on the total extent
Applying Biodiversity and Ecosystem Function Theory to Turfgrass Management
Research on the Biodiversity and Ecosystem Function theory that shows enhanced C storage, N retention, and weed suppression in natural and managed ecosystems, which are traits that are relevant to turfgrass systems are summarized.
Elevated soil nitrogen pools after conversion of turfgrass to water-efficient residential landscapes
As a result of uncertain resource availability and growing populations, city managers are implementing conservation plans that aim to provide services for people while reducing household resource
Effect of urbanization on soil methane and nitrous oxide fluxes in subtropical Australia
It is highlighted that urbanization can substantially alter soil GHG exchange by altering plant soil water use and by increasing bulk density and inorganic N availability, however, on well-drained subtropical soils, the impact of urbanization on inter-annual non-CO2 GWP of turf grass was low compared to urbanized ecosystems in temperate climates.
Carbon Dynamics and Sequestration in Urban Turfgrass Ecosystems
Urbanization is a global trend. Turfgrass covers 1.9% of land in the continental US, occupying about 16 million ha. In this article, we review existing literature associated with carbon (C) pools,
Carbon Sequestration under Warm Season Turfgrasses in Home Lawns
Estimating carbon (C) sequestration in soil as affected by turfgrass species indicates that turfgrass home lawns may be an important contribution to the global carbon sequestration level.
Urbanisation-related land use change from forest and pasture into turf grass modifies soil nitrogen cycling and increases N 2 O emissions
Abstract. Urbanisation is becoming increasingly important in terms of climate change and ecosystem functionality worldwide. We are only beginning to understand how the processes of urbanisation


Assessing soil carbon sequestration in turfgrass systems using long-term soil testing data
As part of the urbanization process, an increasing percentage of land throughout the USA is being converted into turfgrass. Because of high productivity and lack of soil disturbance, turfgrass may be
Field measurements from the Oregon Transect Ecological Research project (OTTER) were used to validate selected process simulations in the FOREST-BGC eco- system model, proving the water-holding capacity of the rooting zone and the maximum surface conductance for photosynthesis and transpiration rates proved to be critical system variables that defied routine field verification.
BIOME-BGC simulations of stand hydrologic processes for BOREAS
BIOME-BGC is a general ecosystem model designed to simulate hydrologic and biogeochemical processes across multiple scales. The objectives of this investigation were to compare BIOME-BGC estimates of
Clipping Management and Nitrogen Fertilization of Turfgrass: Growth, Nitrogen Utilization, and Quality
It was found that N fertilization rates could be reduced 50% or more without decreasing turfgrass quality when clippings were returned, and overall, returning grassClippings was found to improve growth and quality of turfgrass while reducing N fertilizing needs.
Parameterization and Sensitivity Analysis of the BIOME–BGC Terrestrial Ecosystem Model: Net Primary Production Controls
Abstract Ecosystem simulation models use descriptive input parameters to establish the physiology, biochemistry, structure, and allocation patterns of vegetation functional types, or biomes. For
Global net carbon exchange and intra‐annual atmospheric CO2 concentrations predicted by an ecosystem process model and three‐dimensional atmospheric transport model
A generalized terrestrial ecosystem process model, BIOME-BGC (for BIOME BioGeoChemical Cycles), was used to simulate the global fluxes of CO 2 resulting from photosynthesis, autotrophic respiration,
FOREST-BGC, A general model of forest ecosystem processes for regional applications. II. Dynamic carbon allocation and nitrogen budgets.
The model successfully showed dynamic annual carbon partitioning controlled by water and nitrogen limitations, and showed simulated leaf area index ranging from 4.5 for a control stand at Missoula, to 11 for a fertilized stand at Madison, with Year 50 stem carbon biomasses.
