Regional model for nitrogen fertilization of site-specific rainfed corn in haplustolls of the central Pampas, Argentina
(Springer, 2011-12)In semi-arid regions, soil water and nitrogen (N) are generally limiting factors for corn (Zea mays L.) production; hence, implementation of appropriate N fertilization strategies is needed. The use of precision agriculture ... -
Rentabilidad de la agricultura de precisión: estimación de márgenes netos del cultivo de maíz con dosis fijas y variables de insumos
(Asociación Argentina de Economía Agraria, 2019-10-20)En el mundo surgen continuamente nuevas y mejores tecnologías de agricultura de precisión; éstas son expuestas a diversos tipos de ensayos y pruebas para demostrar su impacto productivo, pero raras veces se evalúan desde ... -
Resprouting increases seedling persistence likelihood after fire in a semelparous bamboo species
(Elsevier, 2020-08-18)Chusquea culeou is a semelparous bamboo species which dominates the understorey of temperate forests and shrublands of Patagonia, South America. After the massive flowering, seeding and subsequent die-off, it provides an ... -
Retencion y degradación de glifosato en mezclas de rastrojo de maíz y soja con suelo
(2014-12)Se estudió el comportamiento de 14C-glifosato en la zona de transición rastrojo-suelo, en cuatro sitios y dos secuencias de cultivo: monocultivo de soja (Glycine max (L) Merr), y rotación soja-maíz (Zea mays L). La ... -
Retention and redistribution of biological legacies generate resource sinks in silvopastoral systems of Arid Chaco forests
(Springer, 2019-07-11)Background: Forests are used for multiple purposes worldwide, which often include timber harvest, firewood extraction and livestock raising. An excessive pressure on multipurpose systems may decrease soil cover, promoting ... -
