Analysis of factors controlling maize yield response to hairy vetch and to nitrogen fertilization after hairy vetch
Carciocchi, Walter Daniel; Cafaro La Menza, Nicolás; Crespo, Cecilia; Domínguez, Germán; Rodríguez, M.P.; Reussi Calvo, Nahuel Ignacio; Wyngaard, Nicolás; Sainz Rozas, Hernan Rene; Studdert, Guillermo; Barbieri, Pablo (Elsevier, 2023-11)Context or problem: Several agricultural producers around the world are adopting hairy vetch (HV) (Vicia villosa Roth) inclusion in the crop sequence before maize (Zea mays L.). To date, it is not clear which factors control ... -
Effect of intensified cropping sequences on soil physical properties in contrasting environments
Crespo, Cecilia; Wyngaard, Nicolás; Sainz Rozas, Hernan Rene; Studdert, Guillermo; Barraco, Miriam Raquel; Gudelj, Vicente Jorge; Barbagelata, Pedro Anibal; Barbieri, Pablo (Elsevier, 2021-08-27)Soybean (Glycine max (L.) Merr.) monoculture contributes to soil degradation. Intensification of soybean-based sequences through polyculture, cover crops (CC), and crop fertilization can enhance soil physical quality and ... -
Effect of the intensification of cropping sequences on soil organic carbon and its stratification ratio in contrasting environments
Crespo, Cecilia; Wyngaard, Nicolás; Sainz Rozas, Hernan Rene; Studdert, Guillermo; Barroco, Mirian; Gudelj, Vicente Jorge; Barbagelata, Pedro Anibal; Barbieri, Pablo (Elsevier, 2021-01-19)In environments where continuous agriculture leads to soil organic carbon (SOC) depletion, intensification practices (i.e. polyculture, cover crops (CC), and crop fertilization) have been suggested as strategies to improve ... -
Extracting DNA of nematodes communities from Argentine Pampas agricultural soils
Mondino, Eduardo Ariel; Covacevich, Fernanda; Studdert, Guillermo; Pimentel, João Pedro; Berbara, Ricardo Luiz Louro (2015)We examined four strategies (Tris/EDTA, sodium dodecyl sulfate, Chelex 100 resin and cetyltrimethylammonium bromide -CTAB-) for extracting nucleic acid (DNA) from communities of nematodes. Nematodes were isolated from ... -
How does soil organic carbon mediate trade-offs between ecosystem services and agricultural production?
Villarino, Sebastian; Studdert, Guillermo; Laterra, Pedro (Elsevier, 2019-08)The basis and essence of life on earth depends on soil health, and its main indicator is the soil organic carbon (SOC) content. Hence, SOC stock is a key component for the supply of many ecosystem services (SOC-mediated ... -
Un método simple y práctico para la determinación de densidad aparente
Agostini, María de los Angeles; Monterubbianesi, María Gloria; Studdert, Guillermo; Maurette, Santiago (2014)La condición física del suelo es fundamental para definir su calidad/salud y es afectada por el uso. Por ello, es necesario el seguimiento de los cambios en la condición física de los suelos bajo producción, a través de ... -
Nitrógeno incubado en anaerobiosis y carbono orgánico en suelos agrícolas de buenos aires
Reussi Calvo, Nahuel Ignacio; Studdert, Guillermo; Calandroni, Mirta Beatriz; Diovisalvi, Natalia Verónica; Cabria, Fabián Néstor; Berardo, Angel (2014)El carbono orgánico (CO) y el nitrógeno (N) incubado en anaerobiosis (Nan) son indicadores de calidad del suelo. Además, el Nan es un estimador del aporte de N por mineralización, y ha sido empleado para el ajuste de la ... -
Soil organic carbon changes simulated with the AMG model in a high-organic-matter Mollisol
Moreno, Rocio; Studdert, Guillermo; Monterubbianesi, María Gloria; Irigoyen, Andrea Inés (Sociedad Española de la Ciencia del Suelo, 2016)Soil organic carbon (SOC) management requires a precise knowledge of how it is affected by soil use. Simulation models could help for this purpose. The AMG model is simple, requires information that is easily available, ... -
Soil organic carbon in cropping sequences with predominance of soya bean in the argentinean humid Pampas
Martinez, Juan Pablo; Crespo, Cecilia; Sainz Rozas, Hernan Rene; Echeverria, Hernan Eduardo; Studdert, Guillermo; Martinez, Fernando Gabriel; Cordone, Graciela; Barbieri, Pablo (Wiley, 2020-01)Soya bean (Glycine max (L.) Merr.) monoculture can lead to a decrease in labile fractions of soil organic carbon (SOC). This study sought to evaluate the effects of cover crops (CC), application of fertilizer, and crop ... -
Variación estacional de carbono orgánico particulado y nitrógeno anaeróbico
Studdert, Guillermo; Dominguez, Germán Franco; Zagame, María Cristina; Carabaca, Juan Carlos (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 ...
