Servicio de riego mediante Internet y dispositivos móviles. Colegio de Postgraduados
Aguado Rodríguez, Graciano Javier.
Hoy en día existe la tecnología para realizar actividades de manera automática y en tiempo real en diversos campos de la investigación. Entre las aplicaciones más importantes en agricultura destaca la automatización del riego, determinación del momento del riego y cálculo de la lámina de riego necesaria para abastecer al suelo de alguna parcela y llevarlo a tener humedad a capacidad de campo. Por ello en esta investigación se planteó elaborar un sistema integrado que sea capaz de estimar el Contenido Volumétrico de Agua en el Suelo (WVC) de varias parcelas mediante el cálculo de un Balance Hídrico Climático (BHC) a nivel horario con el método de Allen (2006). Adicionalmente, en caso de tener disponibilidad de una red de estaciones meteorológicas, se...

Brazilian climate normals for 1981-2010 PAB
Diniz,Francisco de Assis; Ramos,Andrea Malheiros; Rebello,Expedito Ronald Gomes.
Abstract: In the last decades, especially since 2000, the natural vulnerability of Earth’s climate system has been a cause of great concern as to the status of global climate change due to the interference of natural and/or anthropic activities. Instituto Nacional de Meteorologia (Inmet), the government body officially responsible for monitoring weather and climate in Brazil, and also a member of the World Meteorological Organization (WMO), is proud to release the new edition of the climate normals for the period of 1981-2010. The new edition aims to analyze and register the climate changes that occurred during the two decades following the previous edition of 1961-1990. For that purpose, Inmet created a working group to prepare and edit these normals, as...

Patterns of litter production in a secondary alluvial Atlantic Rain Forest in southern Brazil Rev. Bras. Bot.
Scheer,Maurício Bergamini; Gatti,Gustavo; Wisniewski,Celina; Mocochinski,Alan Yukio; Cavassani,André Targa; Lorenzetto,Alexandre; Putini,Francisco.
Above-ground litter production is one of the most accessible ways to estimate ecosystem productivity, nutrient fluxes and carbon transfers. Phenological patterns and climatic conditions are still not fully explained well for tropical and subtropical forests under less pronounced dry season and non-seasonal climates, as well as the interaction of these patterns with successional dynamics. Monthly litterfall was estimated for two years in a 9 to 10 year old secondary alluvial Atlantic Rain forest. Total litterfall was higher in the site with more developed vegetation (6.4 ± 1.2 ton ha-1 year-1; 95% confidence interval) as compared to the site with less developed vegetation (3.0 ± 1.0 ton ha-1 year-1). The monthly production of 11 litter fractions (eight...
