Agriculture influences ammonium and soluble reactive phosphorus retention in South American headwater streams
(John Wiley & Sons Inc, 2019-12)
Agricultural activities can affect the delivery of nutrients to streams, riparian canopy cover, and the capacity of aquatic systems to process nutrients and sediments. There are few measures of nutrient uptake and metabolism ...
La superficie específica de oxisoles y su relación con la retención hídricaSpecific surface of oxisols and its relationship with water retention
(Universidad Nacional de Cuyo. Facultad de Ciencias Agrarias, 2016)
Site-specific data on herbicide soil retention and ancillary environmental variables
(Elsevier, 2019-12)
This article presents original geospatial data on soil adsorption coefficient (Kd) for two widely used herbicides in agriculture, glyphosate and atrazine. Besides Kds, the dataset includes site-specific soil data: pH, total ...
The ammonium channel NOD26 is the evolutionary innovation that drives the emergence, consolidation, and dissemination of nitrogen-fixing symbiosis in angiosperms
(Springer, 2018-10)
Increasing evidence indicates that N-fixing symbiosis has evolved several times in the N-fixing clade of angiosperms and that this evolution is driven by a single evolutionary innovation. However, the genetics of this ...
Hydrogels: An Effective Tool to Improve Nitrogen Use Efficiency in Crops
(Springer, 2019)
Hydrogels are hydrophilic polymeric materials with three-dimensional(3D) network structures physic and/or chemically crosslinked. They can absorb large amounts of water or aqueous solutions for a short period of time. When ...
Digestible protein requirements for maintenance, growth, and efficiency of protein utilization in pacu (Piaractus mesopotamicus) juveniles: an exponential nitrogen utilization model
(Pontificia Universidad Católica de Valparaíso, 2021)
Glyphosate and nutrient retention in preferential flow pathways
(Asociación Argentina de Ecología, 2019-12)
Riparian vegetation strips (RVS) reduce surface runoff volume and retain sediments, pesticides and nutrients that are transported across them from adjacent crop-fields (CF). The ability of these strips to retain glyphosate ...
Stability and control of a partial nitritation reactor with biomass retention
(Institution of Chemical Engineers, 2019-04)
Partial nitritation–anammox process is an interesting process option for biological nitrogen removal from wastewater. Partial nitritation needs to provide about equimolar ammonium and nitrite concentrations as required for ...
Cover crops in the Southeastern region of Buenos Aires, Argentina: effects on organic matter physical fractions and nutrient availability
(Springer Verlag, 2018-06)
In the Southeastern region of Buenos Aires province, soybean monoculture has led to a decline in soil organic matter (SOM) levels in soil, mostly the labile fractions. The reduction of SOM has a negative impact on the soil ...
The effects of hydraulic and organic loadings on the performance of a full-scale facultative pond in a temperate climate region (Argentine Patagonia)
(Springer, 2012-06)
This work focuses on the performance of a primary facultative pond, in a full-scale waste stabilization pond system, located in a temperate climate region (average air temperature in winter, 7.7°C; spring and autumn, 14.0°C; ...
