This book was released on 1963 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Se presentan los resultados obtenidos en dos ensayos de fertilización nitrogenada con arroz para dos suelos de repetición, observando su efecto sobre el rendimiento físico (qqm/há) e industrial (porcentaje de grano entero). La experiencia se llevó a cabo en la temporada 1961-62, en dos localidades ubicadas en Chillán y Linares con la variedad de arroz Mapufen. De las observaciones hechas en el terreno durante el desarrollo del cultivo, llamó especialmente la atención el enmalezamiento del ensayo, principalmente con Echinochloa crusgalli (Hualcacho). Las parcelas que tenían nitrógeno en las dosis superiores presentaban un bajo grado de infestación, el cual aumentaba progresivamente, al disminuir el nitrógeno aplicado, presentando el más alto grado de enmalezamiento las parcelas testigos, sin nitrógeno.

This book was released on 2017-09-01 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: La agroecología puede fortalecer a las comunidades marginadas, restaurar los ecosistemas y proteger las fincas de la destrucción ecológica, al mismo tiempo aporta para frenar el el cambio climático. Estas prácticas son efectivas pero todavía no se aplican en todo el mundo. El libro Tierra Fértil, editado por el director ejecutivo de Groundswell International Steve Brescia, nos presenta nueve ejemplos en los cuales los campesinos dirigen movimientos agroecológicos en sus comunidades. Su trabajo en África, Latinoamérica, el Caribe, América del Norte y Europa profundiza las prácticas agroecológicas en muchas comunidades , estas prácticas y principios los comparten con los métodos de Campesino a Campesino, y establecen estructuras organizativas que apoyan a organizaciones gubernamentales y civiles. Tierra Fértil nos muestra métodos para expandir la agroecología con comunidades rurales para que ellas se beneficien con sus propias soluciones y sabiduría.

Available in PDF, EPUB and Kindle. Book excerpt: In terrestrial ecosystems, soil microorganisms and soil animals are essential for litter degradation, soil formation and the availability of nutrients and trace elements. The measurement of biological soil parameters allows a rapid evaluation of the effects of chemical and physical influences due to pollutants or soil management. This book introduces a number of well proved methods for the analysis of carbon, nitrogen, phosphorus and sulfur cycles. It focuses further on the determination of the number and biomass of microorganisms, algae and animals in the soil. Particular emphasis is placed on the comprehensible and complete description of the experimental procedures.

Download or read book Costa Rican Ecosystems written by Maarten Kappelle and published by University of Chicago Press. This book was released on 2016-04-15 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1502, Christopher Columbus named Costa Rica, and while gold and silver never materialized to justify the moniker of rich coast in purely economic terms, scientists and ecotravelers alike have long appreciated its incredible wealth. Wealth in Costa Rica is best measured by its biodiversityhome to a dizzying number of plants and animals, many endemic, it s a country that has long encouraged and welcomed researchers from the world over, and is exemplary in the creation and commitment to indigenous conservation and management programs. Costa Rica is considered to have the best preserved natural resources in Latin America. Approximately nine percent (about 1,000,000 acres) of Costa Rica has been protected in 15 national parks, and a comparable amount of land is protected as wildlife refuges, forest reserves or Indian reservations. This long-awaited synthesis of Costa Rican ecosystems is an authoritative presentation of the paleoecology, biogeography, structure, conservation, and sustainable use of Costa Rica s ecosystems. It systematically covers the entire range of Costa Rica s natural and managed, terrestrial, freshwater and marine ecosystems, including its island systems (Cocos Islands), the Atlantic and Pacific oceans and shores (coasts, coral reefs, mangrove forests), its lowlands (dry, season and wet forests), its highlands (the northern volcanoes and southern Talamanca s), and its estuaries, rivers, lakes, swamps and bogs. The volume s integrated, comprehensive format will be welcomed by tropical and temperate biologists alike, by biogeographers, plant and animal ecologists, marine biologists, conservation biologists, foresters, policy-makers and all scientists, natural history specialists and all with an interest in Costa Rica s ecosystems."

Download or read book The Soils of Ecuador written by José Espinosa and published by Springer. This book was released on 2017-10-24 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to comprehensively discuss Ecuadorian soils. Richly illustrated, it provides information on the unique characteristics and distribution of these soils. Due to the influence of the Andes, which vastly modified the climate and parental materials, a relative small country like Ecuador has a wide variety of soil orders, rarely found in other countries. The country is divided into three distinctive regions by the Andes: The Coastal Plain, the Andean Highlands, and the Amazonia Region each with different soil development, influenced by the varying conditions in that region. It is also necessary to consider the Galapagos Islands as a separate region with a particular climate and parental material.
