Soil Carbon and Nitrogen Dynamics Across the Hillslope-Riparian Interface in Adjacent Watersheds with Contrasting Cellulosic Biofuel Systems
… was assessed in each watershed using an in situ litter bag method. Seasonal in situ net nitrogen mineralization was measured using a sequential core method, and an anaerobic incubation for N mineralization potential of composite soils was performed in the laboratory. Results revealed high …

Transport and decomposition of allochthonous litter in Icelandic headwater streams: Effects of forest cover
… and forested catchments in Iceland in terms of litter transport into streams and litter decomposition within them. This was the first study made in Iceland on the terrestrial-aquatic interactions in forested ecosystems. The main study consisted of nine run-off fed headwater streams in …

Effects of soil temperature on Sphagnum moss litter quality and decomposition in a subarctic environment
… this study, I show how soil temperature affects litter quality and decomposition rates of two Sphagnum species: S. papillosum and S. subnitens. I established a reciprocal litter bag experiment over a thermal gradient in Iceland to measure mass loss (%) of the Sphagnum moss litters over a 4-month …

Monitoreo del proceso de mineralización de tres especies de leguminosas (Vigna radiata, Vigna unguiculata y Mucuna sp) usadas como abono verde en el municipio de San Dionisio, departamento de Matagalpa, Nicaragua
… de las especies en parcelas bases, método de Litter Bag, utilizándose el método de siembra al chorrillo. En la estimación de la producción de materia verde (M. V) y materia seca (M.S) el oowpea fue la especie que presento la mayor producción con 18.15 ton M. V 1 ha y 13.81 ton MS 1 ha, seguido …

Belowground impacts of regenerative agriculture in a South African seed production system
… Secondly, decomposition rate (k), remaining litter mass (g), carbon to nutrient ratios and soil mesofauna community compositions were compared between agricultural treatments, by means of a litter bag experiment (Chapter 3). Multivariate analyses based on decomposition rate with respect to …

Effects of Litter Production, Biochemistry and Plant Community Composition on Carbon and Nutrient Cycling under Elevated Carbon Dioxide and Tropospheric Ozone.
… biochemistry and species composition of leaf litter, which will affect litter decomposition, thereby controlling nutrient release rates and soil carbon formation. To assess those effects, leaf litter was collected from aspen (Populus tremuloides Michx) and birch (Betula papyrifera Marsh) …
