This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Apesar dos esforços da pesquisa em FBN na cultura de cana-de-açúcar, que vem sendo desenvolvida no Brasil, as soqueiras da maioria das variedades de cana-de-açúcar ainda precisam de uma complementação com fertilizantes nitrogenados, e o custo deste insumo tende a elevar-se, acompanhando o preço do petróleo. Assim, nos últimos anos, a pesquisa científica, vem trabalhando em busca de alternativas à adubação nitrogenada, através de genótipos com maior potencial para FBN, práticas de manejo da cultura que poderiam amplificar a contribuição da FBN e pela seleção e inoculação de estirpes de bactérias eficientes para FBN. Buscando alcançar algumas dessas respostas, na Embrapa Agrobiologia, localizada em Seropédica-RJ, foram instalados três experimentos com o objetivo identificar as variedades de cana-de-açúcar mais eficientes para FBN, com base nas técnicas de balanço de N-total no sistema solo/planta, abundância natural de 15N e diluição isotópica de 15N. Os resultados desses experimentos permitiram concluir que: 1) o balanço de N-total do sistema solo-planta após 8 e 13 anos de cultivo foram positivos para a maioria das variedades FBN para o sistema solo-planta; 2) os genótipos Krakatau, SP 70-1143, SP 79-2312 e SP 71-6163 confirmaram o potencial para FBN já observados em estudos anteriores; 3) as variedades RB 72-454, e RB 82-5336, RB 75-8540 e RB 83-5089 apresentaram alto potencial para FBN; 4) o tipo de solo e o ciclo da cultura teve grande influência na contribuição da FBN; e 5) a FBN é uma importante fonte de N ao sistema solo planta, e vislumbram a possibilidade de que com o manejo adequado (colheita de cana crua) e com a utilização de variedades eficientes para FBN, talvez, seja possível reduzir ou mesmo eleiminar a adubação com fertilizantes nitrogenados na cultura.

Download or read book Plant-Microbe Interactions in Agro-Ecological Perspectives written by Dhananjaya Pratap Singh and published by Springer. This book was released on 2017-12-15 with total page 766 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book puts an updated account on functional aspects of multiphasic microbial interactions within and between plants and their ecosystem. Multipronged interaction in the soil microbial communities with the plants constitute a relay of mechanisms that make profound changes in plant and its micro-environment in the rhizopshere at physiological, biochemical and molecular levels. In agro-ecological perspectives, such interactions are known to recycle nutrients and regulate signalling molecules, phytohormones and other small molecules that help plant growth and development. Such aspects are described deeply in this book taking examples from various crop plants and microbial systems. Authors described the most advantageous prospects of plant-microbe interaction in terms of inoculation of beneficial microorganisms (microbial inoculants) with the plants in which microbes proliferate in the root rhizosphere system and benefit plants' with definite functions like fixation of nitrogen, solubilization and mobilization of P, K, Zn and production of phytohormones. The subject of this book and the content presented herein has great relevance to the agro-ecological sustainability of crop plants with the help of microbial interactions. The chapters presented focus on defining and assessing the impact of beneficial microbial interactions on different soils, crops and abiotic conditions. This volume entails about exploiting beneficial microbial interactions to help plants under abiotic conditions, microbe-mediated induced systemic tolerance, role of mycorrhizal interactions in improving plant tolerance against stresses, PGPR as nutrient mobilizers, phytostimulants, antagonists and biocontrol agents, plant interactions with Trichoderma and other bioagents for sustainable intensification in agriculture, cyanobacteria as PGPRs, plant microbiome for crop management and phytoremediation and rhizoremediation using microbial communities. The overall content entrust advanced knowledge and applicability of diversified biotechnological, techno-commercial and agro-ecological aspects of microbial interactions and inoculants as inputs, which upon inoculation with crop plants benefit them in multiple ways.

Download or read book Sugarcane Bioethanol written by Luís Augusto Barbosa Cortez and published by . This book was released on 2010 with total page 994 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Brazil, sugarcane ethanol supplied, in 2009, 17.6 % of the energy for land transportation (excluding railroads)and about 55% of the total energy supplied by liquid fuel for Otto cycle engines. Besides the lower production costs ethanol produced from sugarcane in Brazil has another important advantage: in Central-South Brazil only 1 unit of fossil energy is used for each 8-9 units of energy produced by ethanol from sugarcane. Carbon emissions reduction also benefits from sugarcane ethanol: for each cubic meter of ethanol used as fuel, there is net saving of around 2 t CO2 not emitted to the atmosphere while, at the same time, no SO2 is emitted. Sugarcane was introduced in Brazil in 1532. The "Brazilian model" of producing concomitantly sugar and ethanol, brought important technical benefits and made possible an outstanding increase in the competitiveness in the international market for sugar and ethanol. Today about 50% of the sucrose of sugarcane produced in the country is directed to the production of sugar while another half is used to produce Ethanol. Industrial and academic R&D has helped to increase the productivity of ethanol steadily over the past 35 years, at a rate of 3.2% per year. Productivity gains implied savings of planted area by a factor of 2.6. In 2009/2010 the area planted with sugarcane for Ethanol production was 4.2 Mha, amounting to 1% of the total arable land available in Brazil. About 60% of the Ethanol produced in Brazil comes from the State of Sao Paulo, where the productivity is the highest (around 86 t/ha.year). Most of the recent expansion is happening in the center-west region of the country, in degraded pasture lands. The FAPESP Program for Research on Bioenergy, BIOEN, aims at articulating public and private R&D, using academic and industrial laboratories to advance and apply knowledge in fields related to ethanol production in Brazil. The BIOEN Program has a solid core for supporting academic exploratory research activities that will generate new knowledge and form scientists and professionals essential for advancing industry capacity in ethanol related technologies. On top of this, BIOEN includes partnerships with industry for cooperative R&D activities between industrial and academic laboratories, which are to be co-funded by FAPESP and industry.Federal agencies, such as CNPq, will also co-fund the research.

This book was released on 2017-06-10 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the diversity of tropical microorganisms and its applications in agriculture, renewable energy production and environmental protection. It covers several tropical habitats such as rain forests, mangroves, sea and river waters and describes how microorganisms isolated from these regions can be used to control insects and plant diseases, to improve sugar cane and biofuels production among other applications. The book also aims to bring researchers’ attention to the potential of tropical microorganisms for biotechnological purposes, an area that is still far from being well explored.

Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is the most important nutrient in agricultural practice because the availability of nitrogen from the soil is generally not enough to support crop yields. To maintain soil fertility, the application of organic matters and crop rotation have been practiced. Farmers can use convenient chemical nitrogen fertilizers to obtain high crop yields. However, the inappropriate use of nitrogen fertilizers causes environmental problems such as nitrate leaching, contamination in groundwater, and the emission of N2O gas. This book is divided into the following four sections: “Ecology and Environmental Aspects of Nitrogen in Agriculture”, “Nitrogen Fertilizers and Nitrogen Management in Agriculture”, “N Utilization and Metabolism in Crops”, “Plant-Microbe Interactions”.
