A pesar de la gran diversidad floristica entre suelos y zonas de los pastizales rioplatenses, existen caracteristicas comunes como: la baja proporcion de leguminosas y relaciones de gramineas invernales y estivales, que favorecen generalmente a las segundas. Por otra parte, los suelos en los cuales se apoyan son moderadamente acidos y poseen contenidos bajos de nutrientes, limitando seriamente su productividad en los periodos de baja actividad biologica. Esas tres caracteristicas determinan escasa produccion invernal y baja calidad del forraje ofrecido en primavera-verano. Al mismo tiempo, el pastoreo con una carga constante de ovinos, vacunos y equinos, ha provocado la degradacion, y la consecuente disminucion de la productividad de las pasturas naturales. La utilizacion de fertilizaciones nitrogenadas estrategicas y el manejo del pastoreo constituyen dos herramientas esenciales para aumentar su productividad otono-invernal y mejorar su composicion botanica.

Los ecosistemas de zonas aridas son especialmente suceptibles a los disturbios naturales y a los causados por el hombre, pudiendo desencadenar procesos erosivos que conducen a la desertificacion. En los pastizales pampeanos templados de la region semiarida central Argentina, los disturbios mas comunes estan asociados al sobrepastoreo, el fuego, y la labranza y posterior abandono. En este trabajo evaluamos durante cuatro anos los efectos de estos disturbios en forma individual y combinada, sobre la diversidad y estabilidad (resistencia y resiliencia) de un pastizal ubicado en la provincia de San Luis, Argentina. Los resultados revelan el modo en que la ocurrencia de disturbios modifica la estructura y funcion del ecosistema a traves de cambios en la distribucion espacio-temporal de las especies dominantes. Este libro puede ser de utilidad para estudiantes y profesionales de las ciencias biologicas y agronomicas, como asi tambien para el publico en general interesado en aplicar los conocimientos ecologicos al manejo sostenible de pastizales naturales."

This book provides the first comprehensive overview of saline and alkaline soils in Latin America, known for having one of the most extensive surface of salt-affected soils in the world. It is organized along two main axes: soils and vegetation. The book discusses the occurrence of such soils in the region, focusing mainly in management strategies for their sustainable use, and it presents accounts of natural vegetation and crops in the various environments of the region. Social impacts of such conditions and ongoing projects to overcome them are considered. Likewise, the book highlights physiological mechanisms that are responsible for the negative effects these soils exert on crops and forest resources and determine vegetation distribution in them. Plant breeding challenges and new perspectives for such environments are discussed. Technologies such as irrigation and drainage are included. The readership includes soil and plant scientists, as well as policy makers.

Silvopastoral Systems In Southern South America written by Pablo Luis Peri and has been published by Springer this book supported file pdf, txt, epub, kindle and other format this book has been release on 2016-03-02 with Technology & Engineering categories.
This multi-authored volume contains peer-reviewed chapters from leading researchers and professionals in silvopastoral systems topic in Southern South America (Argentina, Chile and South Brazil). It is a compendium of original research articles, case studies, and regional overviews and summarizes the current state of knowledge on different components and aspects (pasture production, animal production, trees production, carbon sequestration, conservation) of silvopatoral systems in native forests and tree plantations. The main hypothesis of the book is that farmers have integrated tree and pasture/grassland species in their land use systems to reach higher production per unit of land area, risk avoidance, product diversification, and sustainability. These production systems also impact positively in main ecosystem processes. Management of these productive systems, Policy and Socioeconomic Aspects provide great opportunities and challenges for farmers and policy makers in our region. The book is unique on this subject in Southern South America and constitutes a valuable reference material for graduate students, professors, scientists and extensionists who work with silvopastoral systems.
