An integrative index of Ecosystem Services provision based on remotely sensed data
(Elsevier, 2016-12)We present an approach to generate estimates and to map Ecosystem Services (ES) related to C and water dynamics (Soil Carbon sequestration, evapotranspiration and groundwater recharge) and biodiversity (Avian Richness) ... -
Eco-physiological processes underlying maize water use efficiency response to plant density under contrasting water regimes
(Elsevier, 2020-09)This study quantified maize (Zea mays L.) water use efficiency for grain yield (WUEg) in response to plant density under contrasting water regimes; and focused on relevant eco-physiologial processes underlying the responses ... -
Estimating soil organic carbon through loss on ignition: effects of ignition conditions and structural water loss
(John Wiley & Sons Ltd, 2015-03)Loss on ignition (LOI) is one of the most widely used methods for measuring organic matter content in soils but does not have a universal standard protocol. A large number of factors may influence its accuracy, such as ... -
How does grazing affect soil water availability in the Patagonian steppe?
(Elsevier, 2022-06-01)In the Patagonian steppe, grazing may or may not reduce soil water availability: it may increase evaporative losses, because it reduces plant cover, but may decrease transpiration losses because it decreases plant biomass. ... -
Indicadores de degradación y biomasa radical en mallines de una cuenca hídrica de la Patagonia Austral
(Centro Regional de Investigación Kampenaike, Punta Arenas; Chile., 2021)En Patagonia, los principales disturbios que afectan los mallines se asocian con variaciones inducidas en la napa freática y el pastoreo intensivo y continuo del ganado (Raffaele 1999). En este contexto, el sobrepastoreo ... -
Maize leaf rolling and its response to drying soil and evaporative demand
(Wiley, 2023-05-31)Leaf rolling is an adaptive mechanism associated with water deficiencies; however, the physiological processes and environmental factors contributing to leaf rolling are not fully understood. The objective of this study ... -
Maize transpiration efficiency increases with N supply or higher plant densities
(Elsevier, 2021-03-08)Most of the studies addressing the influence of management practices on seasonal crop water use efficiency (i.e., the ratio between shoot biomass and evapotranspiration in a seasonal scale, WUE(B, ET, s)) have focused on ... -
Métodos para reducir la evaporación
(EEA Ingeniero Juárez, INTA, 2019)El objetivo de esta experiencia fue comparar distintos métodos para disminuir la evaporación. La evaporación es el pasaje del estado líquido al estado gaseoso que se da desde una superficie húmeda. La cantidad de agua que ... -
Prediction of hydraulic conductivity loss from relative water loss: new insights into water storage of tree stems and branches
(Wiley, 2019-04)More frequently occurring, drought waves call for a deeper understanding of tree hydraulics and fast and easily applicable methods to measure drought stress. The aim of this study was to establish empirical relationships ... -
Water and nitrate exchange between cultivated ecosystems and groundwater in the Rolling Pampas
(Elsevier, 2009-12)Understanding nitrogen (N) exchange between cultivated ecosystems and groundwater becomes crucial in the Rolling Pampas where high and variable water table levels are accompanied by increasing N-fertilization rates. Field ...
