Biogeochemical Investigations in Old Growth and Disturbed Forest Sites at Mount Kilimanjaro
… soils and different parameters of the water and nutrient cycle in intact as well as disturbed tropical mountain rainforest sites at Mt. Kilimanjaro in order to assess the long term effects of forest dissection on biogeochemical parameters. For this purpose, the chemical and physical soil …

Coarse Woody Debris in Industrially Managed Pinus taeda Plantations of the Southeastern United States
… establishment habitat, and involvement in the nutrient cycle. Most CWD research has been conducted in old-growth and unmanaged, second-growth forests. However, less is understood about CWD in intensively managed ecosystems, such as industrialized southern pine plantations. The objectives of …

Near-surface hydrology and hydrochemistry under contrasting land-cover
… an in-depth understanding of the water and nutrient cycle. On this basis we compared the involved hydrological pathways for rainfall to reach streams and the nutrient budgets of a tropical rainforest and a pasture. In addition we studied the links of hydrochemical differences to differences …

Benefits of Dung Beetles (Coleoptera: Scarabaeidae) on Nutrient Cycling and Forage Growth in Alpaca Pastures
… presence of these beetles would likely enhance nutrient cycling and pasture growth. However, it is important to remember that dung beetles are just one component of many found in a healthy grassland ecosystem, and the functions of these components are interrelated.

Spatial and temporal variation In greenhouse gas flux as affected by mowing on grasslands of hummocky terrain In Saskatchewan
… the Mixedgrass Prairie has a well-balanced nutrient cycle that includes various GHGs. The grassland ecosystem plays a role in mitigating climate change by retaining carbon that would be released to the atmosphere with poor grazing management or the conversion to arable agriculture. …

Assessing climate and terrestrial water storage controls on evapotranspiration variability: towards improved understanding of watersheds as coupled nature-human systems
… and energy budgets, links the water, carbon and nutrient cycle, and represents the largest water consumption from agricultural sector. Although advances have been made in monitoring and simulating terrestrial ET in last decades, there are still challenges in reconciling and cross-validating ET …

Nutrient Availability from Poultry Litter Co-Products
Phosphorus (P) is a nutrient of concern in the Chesapeake Bay watershed due to nutrient imbalances in areas with confined animal feeding operations. By converting poultry litter to an ash via thermal conversion, nutrients are concentrated and are economical to ship out of nutrient surplus …
