Biomass production, arbuscular mycorrhizae and soil plant-available P under water stress in native perennial grasses
Busso, Carlos Alberto; Bolletta, Andrea Ivana (CRC Press-Taylor & Francis, 2010-10)Precipitation determines vegetation type and species relative composition in plant communities [1]; in addition, it is a primary variable affecting soil water storage and availability. This availability is the most important ... -
Calidad nutricional de silajes de verdeos de invierno en un ambiente del sudoeste bonaerense semiárido = Nutritional quality of winter green fodder silages for a semi-arid environment in the southwest of Buenos Aires
Cerda, Carmen Corina; Rochon, Juan María; Bolletta, Andrea Ivana; Gomez, Daniela Alejandra (Asociación Argentina de Producción Animal (AAPA), 2025-09)Los verdeos de invierno cobran importancia como componentes de la cadena forrajera. La incorporación de ellos como silaje de planta entera permitiría a los sistemas ganaderos cierta independencia del clima, y ser un gran ... -
Efecto de la fertilización nitrogenada en la productividad, valor nutritivo y eficiencia de uso del N en Digitaria eriantha = Effect of nitrogen fertilization on productivity and nitrogen use efficiency in Digitaria eriantha
Lagrange, Sebastian Pablo; Molina, Gonzalo; Bolletta, Andrea Ivana; Alonso, Maximiliano Javier; Gomez, Daniela Alejandra; Frigerio, Karina Laura (Asociación Argentina de Producción Animal (AAPA), 2025-09)Digitaria eriantha es una gramínea megatérmica perenne adaptada a ambientes semiáridos. A pesar de su mayor eficiencia en el uso de nitrógeno (N), los suelos arenosos con bajos niveles de materia orgánica de San Luis ... -
Enhancing the Production and Sustainability of Pasture-Fed Beef Using Non-Traditional Legume Forages
Bolletta, Andrea Ivana (Utah State University, 2020-08)Despite the increasing worldwide demand for beef as a protein source, consumers are concerned about the sustainability of ruminant production systems. Their main concerns are animal welfare for feedlot-fed animals, greenhouse ... -
Estudio económico del modelo de la unidad de producción ganadera de la EEA Bordenave: un enfoque regional comparativo
Torres Carbonell, Carlos Alberto; Lagrange, Sebastian Pablo; Lauric, Miriam Andrea; Bolletta, Andrea Ivana; Alonso, Maximiliano Javier; De Leo, Geronimo (Asociación Argentina de Economía Agraria, 2024-10)La adopción de tecnologías, en los sistemas de producción ganaderos ha demostrado ser un factor clave para mejorar la eficiencia y la sostenibilidad. Aumentar la producción de carne y su rentabilidad en las regiones de ... -
Fruitful controversies in sustainable livestock production: beyond the intensive versus extensive livestock polarization in nonforest ecosystems
Litre, Gabriela; Lagrange, Sebastian Pablo; Arbeletche, Pedro; Champredonde, Marcelo; Bolletta, Andrea Ivana (Elsevier, 2022)Land-use changes, mainly driven by the advancement of large-scale soybean monocultures over extensive livestock production systems, have fostered land concentration in the agribusiness sector and an increase of grain-finished ... -
In Vivo Reductions in Methane and Urinary Nitrogen by Perennial Non-Bloating Temperate Legume and Forb Functional Forages Produced in the Mountain West United States
MacAdam, Jennifer W.; Villalba, Juan J.; Lagrange, Sebastian Pablo; Stewart, Elizabeth K.; Pitcher, Lance R.; Slebodnik, Kathryn A.; Norton, Jeanette M.; Reeve, Jennifer R.; Yunhua, Zhang; Bolletta, Andrea Ivana; Legako, Jerrad F.; Christensen, Rachael G.; Hunt, Sara R. (Wiley, 2025-06)Ruminant livestock production is the greatest source of agricultural greenhouse gas (GHG) production, largely due to enteric methane (CH4) emissions. While the optimised feed rations used in confinement dairy and beef ... -
Increased Nitrogen Retention and Reduced Methane Emissions of Beef Cattle Grazing Legume vs. Grass Irrigated Pastures in the Mountain West USA
MacAdam, Jennifer W.; Pitcher, Lance R.; Bolletta, Andrea Ivana; Guevara Ballesteros, Raúl David; Beauchemin, Karen A.; Xin, Dai; Villalba, Juan J. (MDPI, 2022-01)Grazing studies were carried out over a 5-year period using pregnant cows, yearling calves and 2-year-old heifers to investigate the influence of diet on intake, methane (CH4) emissions and retention of nitrogen (N). ... -
Influence of Soil Water Status on Arbuscular Mycorrhizas in Three Perennial Grasses in Central Argentina
Busso, Carlos Alberto; Bolletta, Andrea Ivana; Flemmer, Andrea Cecilia; Montani, Tomás (Finnish Zoological and Botanical Publishing Board, 2008-12)In this field study, we determined the effects of water stress, rainfed or irrigated conditions on the arbuscular mycorrhizal fungal (AMF) root colonization in the late-seral Stipa clarazii, the earlier-seral S. tenuis and ... -
