Monitoreo de indicadores de degradación en mallines del sur de Santa Cruz
(EEA Santa Cruz, INTA, 2013-02)Los principales disturbios que afectan los mallines en Patagonia se relacionan con variaciones en su dinámica hídrica y el pastoreo intensivo y continuo durante períodos prolongados (Raffaele, 1999) que producen alteraciones ... -
Monitoring drylands: The MARAS system
(Elsevier, 2018-11-09)MARAS (Monitoring of Arid and Semiarid Regions) consists of 379 ground monitors in Patagonia, a 624.500 km2 semiarid area of southern Argentina and Chile. The objective of this paper was to describe the system and analyze ... -
Nutrient resorption in two co existing Nothofagus species in southern Patagonia.
(University of Copenhagen, 2017-08-21)Nutrient resorption understood as the “movement” of nutrients from leaves prior to abscission towards other tissues or internal stores has been suggested to be a key component of nutrient conservation in deciduous forest ... -
Positive feedbacks and alternative stable states in forest leaf types
(Springer Nature, 2024-05-31)The emergence of alternative stable states in forest systems has significant implications for the functioning and structure of the terrestrial biosphere, yet empirical evidence remains scarce. Here, we combine global forest ... -
Precipitation is the key determinant of topsoil δ15N values in southern Patagonia’s semiarid rangelands
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2022-02-11)Nitrogen (N) cycling in rangeland soils could potentially be controlled by water supply, stocking rates, or a range of other variables, such as ecosystem N stocks. To gauge the relative importance and elucidate possible ... -
Provincia de Santa Cruz
(Centro para la Promoción de la Conservación del Suelo y del Agua (PROSA)-INTA, 2019)La obra “Manual de buenas prácticas de manejo y conservación del suelo y del agua en áreas de secano“, pubicada por PROSA-FECIC en el 2019, tiene por objetivo describir las principales prácticas de manejo del suelo y del ... -
Provincia de Tierra del Fuego, Antártida e Islas del Atlántico Sur

Rangeland grazing management in Argentine Patagonia
(IJAB. Friends science publishers, 2020-08-31)Stocking rate adjustment in grazing management is recommended as a management tool to sustain productivity and improve soil health of permanent grassland ecosystems. The aim of this project was to assess the effect of ... -
Sensitivity of global soil carbon stocks to combined nutrient enrichment
(Wiley, 2019-06)Soil stores approximately twice as much carbon as the atmosphere and fluctuations in the size of the soil carbon pool directly influence climate conditions. We used the Nutrient Network global change experiment to examine ... -
Sheep faeces decomposition and nutrient release across an environmental gradient in Southern Patagonia
(2017-04)In Southern Patagonia, most of the land ranging from the mountains to the sea in contrasting environmental conditions is devoted to extensive sheep farming. Existing estimations indicate that in ecosystems under livestock ... -
Silvopastoral use of Nothofagus antarctica forests in Patagonia: impact on soil microorganisms
(Springer, 2022-09-06)Soil microorganisms contribute to soil carbon storage, soil respiration and nutrient cycling. In south Patagonia, there are scarce studies on carbon (C) and nitrogen (N) in soil microbial biomass (MB). The aim of this work ... -
Silvopastoral use of Nothofagus antarctica in Southern Patagonian forests, influence over net nitrogen soil mineralization
(2013-04)In most temperate forest, nitrogen (N) is considered a limiting factor. This becomes important in extreme environments, as Nothofagus antarctica forests, where the antecedents are scarce. Thinning practices in N. antarctica ... -

(EEA Santa Cruz, INTA, 2021-04)El presente informe presenta los resultados de la instalación de indicadores MBGI a una escala predial para la provincia de Santa Cruz. Para esto se tomó como base los indicadores de monitoreo a escala predial obtenido en ... -
Sistemas silvopastoriles y su contribución al uso eficiente de los recursos y los Objetivos de Desarrollo Sostenible: Evidencia desde América Latina
(FAO y CIPAV, 2019)Este documento representa el esfuerzo conjunto entre dos redes de acción de la Agenda Global: (i) Cerrando la brecha de la eficiencia y (ii) la Red Global en Sistemas Silvopastoriles. Un marco de referencia para evaluar ... -
Soil carbon is a useful surrogate for conservation planning in developing nations
(Nature Research, 2019-03)Defining the optimal placement of areas for biodiversity conservation in developing nations remains a significant challenge. Our best methods for spatially targeting potential locations for biodiversity conservation rely ... -
Soil erosion rates and nutrient loss in rangelands of Southern Patagonia
(Elsevier, 2021-11-25)Soil erosion in rangelands is the main driver of desertification as a result of severe drought events and overgrazing reducing potential land productivity. The objectives of this chapter are to provide an overview of soil ... -
Soil Nitrate Profiles and the Risk of Nitrate Leaching in Sweet Cherry Orchards Subjected to Different Management Schemes
(2014)When nitrogen is applied to sweet cherry orchards, losses can take place. The authors determined the soil nitrate distribution in fertilized sweet cherry orchards in Southern Patagonia (Argentina). The treatments were ... -
Survival and growth of Nothofagus pumilio seedlings under several microenvironments after variable retention harvesting in southern Patagonian forests
(INRA : Springer, 2014)Context: Variable retention prescriptions for Nothofagus pumilio forests provide for biodiversity conservation and natural regeneration by controlled opening of the canopy. Harvesting generates different microenvironments ... -
