Soybean and wheat response to lime in no-till Argentinean mollisols
(Elsevier, 2015-09)Crop production in Argentina has significantly increased over the past few years; this increase was consequence of better management practices which included P and N fertilization and, occasionally, S fertilization. Commonly ... -
Soybean grain protein and oil differences between Argentine cropping areas: an on-farn sampling approach
(Donau Soja, 2023-09-21)Soybean (Glycine max (L.) Merr.) is the most important crop in Argentina. It grows in different types of environments along the national area, considering an ample latitudinal range (-21°S to -55°) and different crop ... -
Soybean shows an attenuated nitrogen dilution curve irrespective of maturity group and sowing date
(2016-02-01)It is generally accepted that the nitrogen (N) dilution curves relating shoot nitrogen concentration (%N) and shoot biomass (W) are similar among genotypes from the same species. However, differences in the pattern of ... -
Spatial and temporal variation in the migration of Ruddy-headed Goose in southern South America using satellite tagging
(Cambridge University Press, 2020-04-30)Ruddy-headed Goose Chloephaga rubidiceps is the smallest of the five South American sheldgeese and has two separate populations: one sedentary, which resides in the Malvinas/Falkland Islands and one migratory that overwinters ... -
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 ... -
Spatial–temporal trends and economic losses associated with bovine abortifacients in central Argentina
(Springer, 2022-07-30)The aims of this work are, firstly, to provide the geolocalization of cases of bovine abortion with definitive diagnosis and, secondly, to estimate the economic losses due to the most frequent abortifacients diagnosed ... -
Spatio-temporal variability in the feeding strategy of Andean rodents: the role of ambient temperature and food availability
(Springer, 2023-05)Animals' diets reflect the morpho-physiological and behavioral responses used to obtain nutrients and energy. While optimal foraging theory predicts them in terms of food availability, the obligatory heat model (OHM) ... -
