Grazing increases evapotranspiration without the cost of lowering soil water storages in arid ecosystems
(2017-09)Grazing is the predominant land use practice in arid environments; however, there are relatively few studies of grazing effects on ecosystem functioning. We assessed the impact of grazing on soil moisture, evapotranspiration ... -
Hydrological and productive impacts of recent land use and land cover changes in the semiarid Chaco: understanding novel water excess in water scarce farmlands
(Wiley, 2020-08)Over the last decades, the rapid replacement of native forests by crops and pastures in the Argentinean semiarid Chaco plains has triggered unprecedented groundwater level raises resulting from deep drainage increases, ... -
Impact of exotic Ponderosa pine (Pinus ponderosa Doug. ex Laws.) plantations on water resources in northwestern Patagonia, Argentina
(Oregon State University, 2007-12)Exotic ponderosa pine (Pinus ponderosa Doug. ex Lawson) plantations are being planted within the natural distribution area of cordilleran cypress (Austrocedrus chilensis (D.Don) Pic. Ser. et Bizzarri) in Patagonia, Argentina. ... -
Influence of management practices on water-related grain yield determinants
(Oxford University Press, 2023-07-25)Adequate management of N supply, plant density, row spacing, and/or soil cover has proved useful to increase grain yields and/or grain yield stability across years of rainfed crops. We reviewed the impact of these management ... -
Informe Agroclimático 2023 en el área de influencia del INTA EEA Paraná
(Estación Experimental Agropecuaria Paraná, INTA, 2024)En este trabajo se presenta una síntesis del comportamiento durante el año 2023 de las precipitaciones, temperaturas, evapotranspiración y cociente fototermal para la zona de influencia de la EEA Paraná -
Informe Agrometeorológico 2023 Bella Vista, Corrientes
(EEA Bella Vista, INTA, 2024-02-05)El presente informe resume las principales variables agrometeorológicas registradas en la estación agrometeorológica convencional perteneciente a la EEA Bella Vista – INTA (Observatorio INTA N°067) durante el año calendario ... -
Normales del clima de la región de Montecarlo
(Universidad Nacional de Misiones, 2019)El objetivo de este trabajo fue obtener las normales climáticas mensuales y anuales de temperatura del aire y precipitación y sus variabilidades, e integrar en un balance hídrico climático la relacion entre la precipitación ... -
Pruning after budburst delays phenology and affects yield components, crop coefficient and total evapotranspiration in Vitis vinífera L. cv. ‘Malbec’ in Mendoza, Argentina
(Elsevier, 2022-02-23)Late pruning is a field technique that has recently been proposed to mitigate the advance in phenology produced by global warming. However, contrasting effects have been observed depending on the cultivar and the date of ... -
Retrieval of Evapotranspiration from Sentinel-2: Comparison of Vegetation Indices, Semi-Empirical Models and SNAP Biophysical Processor Approach
(MDPI, 2019-10)Remote sensing evapotranspiration estimation over agricultural areas is increasingly used for irrigation management during the crop growing cycle. Different methodologies based on remote sensing have emerged for the leaf ... -
Variación temporal de la evapotranspiración de referencia en el área bajo riego de 25 de Mayo, La Pampa
(Asociación Argentina de Agrometeorología, 2016-09-20)El objetivo de este trabajo es analizar los valores medios mensuales de ETo en la cuenca media del río Colorado, y determinar su frecuencia según niveles de probabilidad de ocurrencia. La información obtenida, constituye ... -
Water productivity in soybean following a cover crop in a humid environment
(Elsevier, 2020-02-05)We evaluated the influence of the termination dates of a winter cover crop on (i) soil water availability during soybean (Glycine max L. (Merr)) growing season, (ii) soybean evapotranspiration (ET) and iii) water productivity ... -
Water regulation by grasslands: a global meta‐analysis
(Wiley Online Library, 2018-06-03)Grasslands have been modified and replaced worldwide and have affected water regulation ecosystem services. In order to support public policies attending to the consequences of different grassland modifications and ... -
Water: tools and functions to estimate actual evapotranspiración using Land Surface Energy Balance Models in R
(2016-12)The crop water requirement is a key factor in the agricultural process. It is usually estimated throughout actual evapotranspiration (ETa). This parameter is the key to develop irrigation strategies, to improve water use ... -
Whole plant open chamber to measure gas exchange on herbaceous plant
(2016)Much of our understanding about CO2 and H2O gas exchange in plants has been gained from studies at leaf level. Extrapolation of results to whole plant is difficult and not always accurate. In order to overcome this limitation, ...
