Hybrid sunflower seed yield, composition and deterioration after chemical desiccation
(2017-04)
The impact of chemical desiccation on yield showed contrasting results depending on seed moisture content at the time of application. Its effects on seed deterioration are still unknown and could be modified by seed ...
Modelling effective soil depth at field scale from soil sensors and geomorphometric indices
(2017)
The effective soil depth (ESD) affects both dynamic of hydrology and plant growth. In the southeast of Buenos Aires province, the presence of petrocalcic horizon constitutes a limitation to ESD. The aim of this study was ...
Vicia villosa ssp. villosa Roth field emergence model in a semiarid agroecosystem
(2018-03)
Hairy vetch (Vicia villosa Roth) is a winter annual legume cultivated for pasture and hay with the capability for natural reseeding. Vicia villosa increases N concentrations in the soil, thus contributing to the sustainability ...
Molecular characterization and cluster analysis of field isolates of avian infectious laryngotracheitis virus from Argentina
(2017-12-13)
Avian infectious laryngotracheitis (ILT) is a worldwide infectious disease that causes important economic losses in the poultry industry. Although it is known that ILT virus (ILTV) is present in Argentina, there is no ...
Thinking in the sustainability of Nothofagus antarctica silvopastoral systems, how differ the responses of seedlings from different provenances to water shortage?
(2017-12)
Nothofagus antarctica, is the most important species of the silvopastoral systems of southern Patagonia. However, there is limited information on the ecophysiological response mechanisms of seedlings for survival under ...
Mapping extinction debt highlights conservation opportunities for birds and mammals in the south American Chaco
(2018-02)
Habitat loss is the primary cause of local extinctions. Yet, there is considerable uncertainty regarding how fast species respond to habitat loss, and how time‐delayed responses vary in space.
We focused on the Argentine ...
Soil microbial processes in a pine silvopastoral system in NW Patagonia
(2018-02)
The conversion of native vegetation to tree plantation (afforestation) implies a drastic change in life forms and as a consequence, changes in the microenvironmental conditions, and the quantity and quality of organic ...
Cultivating the dry forests of South America: Diversity of land users and imprints on ecosystem functioning
(2015-12)
In the South American dry forest of the Dry Chaco and Chiquitania, the area under cultivation rose from 10% to 19% over the last 10 years, and little biophysical, economical, or political constrains seem to prevent further ...
A spatial dataset of topsoil texture for the southern Argentine Pampas
(2018-03)
We produced a 1-km spatial resolution dataset of soil texture for the southern Argentine Pampas. Variables related to climate have higher prediction performance for soil texture. The soil texture varies gradually becoming ...
N:P:S stoichiometry in grains and physiological attributes associated with grain yield in maize as affected by phosphorus and sulfur nutrition
(2017-03)
Balanced nutrition is necessary to reduce yield gaps in maize. Simultaneous phosphorus (P) and sulfur (S) deficiencies may be present in soils, so a P × S interaction is expected. In maize, yield is closely related to grain ...
