Soil quality and productivity under zero tillage and grazing on Mollisols in Argentina – A long-term study
Fernandez, Romina; Frasier, Ileana; Noellemeyer, Elke; Quiroga, Alberto Raul (2017-12)The growing global demand for food, fibers and energy has triggered a scientific and political debate on how to attain increasing land productivity without further degrading soils. The objective of this study was to quantify ... -
Soil type affects biological phosphorus cycling more than soil management
Frasier, Ileana; Noellemeyer, Elke; Gili, Adriana; Gomez, María Florencia; Uhaldegaray, Mauricio Gaston; Quiroga, Alberto Raul; Fernandez, Romina; Alvarez, Lucila (Elsevier, 2022-08-10)There is a need for more sustainable management of phosphorus (P) fertilization including reutilization of wastes and taking more advantage of the biological cycling of P in the crop-livestock-soil system to comply with ... -
Soil type, land-use and -management as drivers of root-C inputs and soil C storage in the semiarid pampa region, Argentina
Frasier, Ileana; Quiroga, Alberto Raul; Fernandez, Romina; Alvarez, Cristian; Gomez, Florencia; Noellemeyer, Elke; Scherger, Eric Daniel; Gili, Adriana (Elsevier, 2019-09-01)The objective of the study was to assess the effect of soil type, land-use and -management on root-C inputs and soil carbon storage in the central semiarid pampa region, Argentina. Twenty-one sites were assessed with ... -
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
Fernandez, Romina; Quiroga, Alberto Raul; Alvarez, Cristian; Lobartini, Juan Carlos (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 ... -
Vetch-rye biculture is a sustainable alternative for enhanced nitrogen availability and low leaching losses in a no-till cover crop system
Frasier, Ileana; Noellemeyer, Elke; Amiotti, Nilda Mabel; Quiroga, Alberto Raul (2017-12)The reliance of current farming systems on synthetic fertilizers caused concerns about their sustainability, and alternatives to supply nitrogen through biological processes have to be adapted to practical conditions. The ...
