Soil quality impacts of current South American agricultural practices
(Society for Urban Ecology, 2015)Increasing global demand for oil seeds and cereals during the past 50 years has caused an expansion in the cultivated areas and resulted in major soil management and crop production changes throughout Bolivia, Paraguay, ... -
Sustainability/resilience of soil organic matter components in an Argentinean arid region
(Centro SECS de Documentación en Ciencias del Suelo (Ce.SECS), 2013-04-05)This short communication presents a novel approach to determining the soil sustainability of productive practices in an Argentinean arid region, using the resilience degree of soil organic matter components. The study was ... -
The effect of agriculture on topsoil carbon stocks is controlled by land use, climate, and soil properties in the Argentinean Pampas
(Elsevier, 2022-05)The conversion of native grasslands into croplands with a high frequency of soybean (Glycine max L.) in crop rotations has diminished soil organic carbon (SOC) stocks in the Argentinean Pampas. The aims of our study were ... -
To burn or not to burn : the question of straw burning and nitrogen fertilization effect on nitrous oxide emissions in sugarcane
(2017)Nitrous oxide (N2O) is the main greenhouse gas emitted from farming systems and is associated with nitrogen (N) fertilizer application as well as decomposition of organic matter present in the environment. The objective ... -
Valores umbrales de algunos indicadores de calidad de suelos en molisoles de la región semiárida pampeana = Threshold values of some soil quality indicators in the semiarid pampas
(Asociación Argentina de la Ciencia del Suelo, 2016)Los objetivos del trabajo fueron evaluar los efectos de variaciones en los contenidos de materia orgánica sobre propiedades edáficas e identificar indicadores simples y de fácil determinación que sirvan para caracterizar ... -
Variación estacional de carbono orgánico particulado y nitrógeno anaeróbico
(2015)Las fracciones lábiles de la materia orgánica como el carbono orgánico particulado (COP) y el nitrógeno (N) liberado en incubación anaeróbica (Nan)) son indicadores de salud edáfica. Sin embargo, sus contenidos pueden ... -
Vertical distribution of root biomass and soil carbon stocks in forage cropping systems
(Springer, 2018-02)Background and aims: Forage cropping systems may differentially affect the vertical distribution of roots and soil organic C stock (C-OM). In annual crops sequences (ACS) and perennial pastures (PP), we assessed the ... -
Winter cover crops in soybean monoculture: effects on soil organic carbon and its fractions
(2016-08)The current agricultural production systems in the Pampas Region have been significantly simplified by cultivating large land areas under no tillage (NT), where soybean is the predominant crop. These systems with long ...
