Nitrogen dynamics during ecosystem development in tropical forest restoration
(ELSEVIER SCIENCE BV, 2011)
We considered whether ecological restoration using high diversity of native tree species serves to restore nitrogen dynamics in the Brazilian Atlantic Forest. We measured delta(15)N and N content in green foliage and soil; ...
Carbon and Nitrogen Dynamics in an Oxisol as Affected by Liming and Crop Residues under No-Till
(SOIL SCI SOC AMER, 2011)
The short-term effects of surface lime application and black oat (Avena strigosa Schreb.) residues, with or without N fertilization, were evaluated in a long-term no-till (NT) system on a sandy clay loam, a kaolinitic, ...
Water Treatment Plant Sludge Discharge to Wastewater Treatment Works: Effects on the Operation of Upflow Anaerobic Sludge Blanket Reactor and Activated Sludge Systems
(WATER ENVIRONMENT FEDERATION, 2010)
This experiment examined the effects of the discharge of water treatment plant (WTP) sludge into the following three types of wastewater treatment systems: a pilot-scale upflow anaerobic sludge blanket (UASB) reactor, a ...
Microbial recycling of dissolved organic matter confines plant nitrogen uptake to inorganic forms in a semi-arid ecosystem
(Elsevier, 2016-10)
Plant uptake of dissolved organic nitrogen (DON) has been proposed to explain inconsistency in the ecosystem N balance of semi-arid systems. Nevertheless, direct evidence for an ecologically important role of DON in plant ...
Impacts of composite wastewater on a Pampean stream (Argentina) and phytoremediation alternative with Spirodela intermedia Koch (Lemnaceae) growing in batch reactors
(Elsevier, 2013-01)
Poultry slaughterhouses are producing increasing amounts of solid organic by-products and waste in Argentina. The objectives of this study are to assess the impacts of wastewater, mainly composed of poultry slaughterhouse ...
Dominance of legume trees alters nutrient relations in mixed species forest restoration plantings within seven years
(Springer, 2008-03-01)
Failures in reforestation are often attributed to nutrient limitation for tree growth. We compared tree performance and nitrogen and phosphorus relations in adjacent mixed-species plantings of contrasting composition, ...
Efecto de dos inhibidores de la nitrificación sobre la concentración de nitratos en pasto elefante (pennisetum purpureum schum.)
(Universidad Nacional de Colombia Sede Palmira, 1986-07-01)
Se compararon dos inhibidores de la nitrificación (Sulfatiazol, N- Serve) y las tendencias de la conversión de amonio a nitrato en el suelo y la concentración de este ión en el pasto según la fuente (Urea, Nitrón 26) y las ...
Sources, Rates and Time of Nitrogen Application on Maize Crops under No-Tillage System
(Taylor & Francis Inc, 2016-01-01)
Quantitatively, nitrogen (N) is the foremost nutrient for maize crops (Zea mays L.), but the N source to increase the grain productivity still needs more investigation. Thus, the aim of this experiment was to study sources, ...
Effect of tropical grass and nitrogen fertilization on nitrous oxide, methane, and ammonia emissions of maize-based rotation systems
(Elsevier B.V., 2020-08-01)
While tropical grasses were shown to inhibit the activity of soil nitrifiers, their role in greenhouse gas (GHG) and ammonia (NH3) emissions in N fertilized maize-based rotations are poorly understood. A 3-year (2014-2017) ...
Feasibility of closing nutrient cycles from black water by microalgae-based technology
(2019-12-01)
Microalgae can recover macronutrients and trace elements from wastewaters. The microalgae biomass can then be used as fertilizer to enrich impoverished agricultural soils by increasing the soil´s carbon content and providing ...
