Forest biomass stocks and dynamics across the subtropical Andes
(Wiley Blackwell Publishing, Inc, 2020-10)
Forest biomass plays an important role in the global carbon cycle. Therefore, understanding the factors that control forest biomass stocks and dynamics is a key challenge in the context of global change. We analyzed data ...
High impact grazing as a management tool to optimize biomass growth in northern Argentinean grassland
(2016-04)
Grasslands are the main source of feed for cattle in Argentina. Standing dead biomass accumulation threatens efficient resource use. The effect and timing of high impact grazing by cattle as a management tool to remove ...
Fire and grazing differentially affect aerial biomass and species composition in Andean grasslands
(Gauthier-Villars/Editions Elsevier, 2011-04)
Grazing and fire have been the most common disturbances in many grasslands ecosystems for many centuries. However, some mountain regions are currently experiencing a decrease in land use, and therefore in frequency or ...
Fluidization of forest biomass-sand mixtures: experimental evaluation of minimum fluidization velocity and CFD modeling
(Taylor & Francis, 2020-07-03)
An experimental fluid-dynamic study of sand-forest biomass mixture fluidization was conducted. Different proportions of biomass/sand were tested. Sawdust from the Abra Ancha sawmill, located in the town of Aluminé, Argentina, ...
Biomass Decomposition and Phosphorus Release from Residues of Cover Crops under No-Tillage
(2017-01)
Under no-tillage field conditions, cover crop (CC) residues remain on the soil surface and decompose at a slow rate. We used three CC species (oat, Avena sativa L.; rye, Secale cereale L.; and ryegrass, Lolium multiflorum ...
Dynamics of aerial and perennial biomass of two lucerne cultivars with different fall dormancy subject to two severities of cutting during the establishment phaseDinámica de la biomasa aérea y perenne de dos cultivares de alfalfa con diferente grado de latencia invernal sujetos a dos severidades de corte durante la etapa de implantación
(Universidad Nacional de La Plata. Facultad de Ciencias Agrarias y Forestales, 2021-06)
The aim of this study was to quantify the impact of two cutting severities on the dynamics of aerial and perennial (root plus crown) biomass of lucerne (Medicago sativa L.) plants of two cultivars of contrasting fall ...
Double Sampling Methods in Biomass Estimates of Andean Shrubs and Tussocks
(Society for Range Management, 2017-11)
The natural Andean vegetation environment is the most important resource available to local pastoralist economies. Knowledge of its attributes is vital in assessing ecosystem properties and improves management decision ...
Implications on feedstock processing and safety issues for semi-batch operations in supercritical water gasification of biomass
(MDPI AG, 2021-05)
Biomass with a large amount of moisture is well-suited to be processed by supercritical water gasification, SCWG. The precipitation of inorganics, together with char formation and repolymerization, can cause reactor plugging ...
Nitrogen and radiation effects during the active spike-growth phase on floret development and biomass partitioning in 2- and 6-rowed barley isolines
(Csiro Publishing, 2010-10)
The paramount importance of accumulated biomass in active-growing spikes over the number of grains per unit area has been well documented. However, it is not clear how different nitrogen (N) and radiation supplies during ...
Biomass, decomposition and nutrient cycling in a SW Atlantic Sarcocornia perennis marsh
(Elsevier, 2015-03)
Biomass dynamics, decomposition and nutrient cycling were studied in a Sarcocornia perennis salt marsh in the Bahia Blanca estuary (Argentina) to achieve a better understanding of these processes and provide information ...
