Can nitrogen isotopes be used to detect the effects of burning on nitrogen cycling? : a study on Pinus resinosa in Minnesota, USA
… in Minnesota, USA were surveyed and fine and coarse roots from stands were analysed for nitrogen isotopes in an attempt to determine if fire effects nitrogen cycling. Fire increased the % nitrogen of coarse roots and changed the ratio of C: N. It may also decrease the depth of the A-horizon. …

Coarse Root, Forest Litter, and Soil Organic Matter Contributions to Carbon Sequestration in Loblolly Pine (Pinus taeda) Plantations in East Texas
… In the summer of 2017, tap root systems and coarse roots on each of the three sites were excavated to quantify belowground biomass. All sites experienced increases in carbon sequestered belowground in coarse roots, tap roots, and also O horizons. Only one site had a statistically significant …

Effects of Elevated Atmospheric CO2 on Root Dynamics, Biomass and Architecture in a Scrub-Oak Ecosystem at Kennedy Space Center, Florida
… belowground structures, in addition to fine roots, are of particular interest because of their role in carbon sequestration. Non-destructive methods, including ground-penetrating radar (GPR) and minirhizotron observation tubes, were used to investigate effects of elevated CO<sub>2</sub> on …

Phenotypic Plasticity within the Native Perennial Grass, Poa secunda (Sandberg bluegrass), an Important Component of the Western United States Sagebrush Grassland Vegetation
… were harvested fifty days after emergence. Roots were rinsed, clipped from leaf mass, and digitally scanned. For the competition experiment, twenty seeds from forty-eight families were sown individually into small and large greenhouse pots and one seed of B. tectorum was added to half of the …

Coarse Root Biomass and Architecture: Applications of Ground Penetrating Radar
… penetrating radar (GPR) to identify and quantify coarse roots was tested in a mixed-oak forest in Southeastern Virginia using experimental pits and locally excavated root segments. GPR was found to be highly dependent on low soil moisture levels as it is unable to differentiate root structures if …

Productivity, Carbon Sequestration, Nutrient Accumulation, And Species Interactions In Perennial Biomass Alley Cropping Systems
… and root C, N, P, and K due to extensive coarse roots. Soil carbon declined slightly over the study period, although alley system roots sequestered up to 7.0 and 6.3 Mg C ha-1 at Empire, and Granada, respectively. At Empire, above– and belowground biomass of herbaceous alley crops declined …

Characterizing the Respiration of Stems and Roots of Three Hardwood Tree Species in the Great Smoky Mountains
Carbon dioxide efflux rates (CER) of stems and roots of overstory and understory black cherry (<i>Prunus serotina</i> Ehrh., BC), red maple (<i>Acer rubrum</i> L., RM) and northern red oak (<i>Quercus rubra</i> L., RO) trees were monitored over two growing seasons at two contrasting sites in the …
