Productividad física y económica del agua en cultivos invernales tradicionales y alternativos en la región semiárida pampeana
Gaggioli, Carolina; Noellemeyer, Elke; Quiroga, Alberto Raul (Facultad de Agronomía, Universidad Nacional de La Pampa, 2020-05-01)Las regiones semiáridas están sometidas a la irregularidad de los fenómenos climáticos, especialmente por la variabilidad anual y mensual en las precipitaciones. En estas condiciones, generalmente la eficiencia de uso del ... -
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 ... -
Spectral indices from aerial images and their relationship with properties of a corn crop
Farrell, Mauricio Aníbal; Gili, Adriana Anahí; Noellemeyer, Elke (Springer, 2018-03)Identification of areas with similar restrictions to crop productivity could improve the efficiency to manage agricultural systems, guarantee stable yields, and reduce the effect of droughts in rainfed systems. The ability ... -
Valores de linea d base para evaluar la degradación en molisoles de la región semiarida pampeana
Fernandez, Romina (Universidad Nacional del Sur, 2018-03-15)Con el objetivo de obtener valores de línea de base para la evaluación de la degradación de suelos se caracterizó la calidad biológica y física de Molisoles bajo diferentes usos de la Región Semiárida Pampeana. El estudio ... -
Variación espacial de los contenidos hídricos del suelo en función del relieve = Topography effect on the spatial variability of soil moisture contents
Montoya, Eugenia María Fernanda; Farrell, Mauricio Aníbal; Noellemeyer, Elke (Asociación Argentina de la Ciencia del Suelo, 2018)El objetivo del presente trabajo es aportar la información de base para caracterizar la distribución de la humedad en perfiles de suelos que corresponden a un paisaje típico del norte de La Pampa. Para tal fin se llevó a ... -
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 ...
