Download or read book Mycorrhizae Sustainable Agriculture and Forestry written by Zaki Anwar Siddiqui and published by Springer Science & Business Media. This book was released on 2008-07-27 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycorrhizal fungi are microbial engines which improve plant vigor and soil quality. They play a crucial role in plant nutrient uptake, water relations, ecosystem establishment, plant diversity, and the productivity of plants. Scientific research involves multidisciplinary approaches to understand the adaptation of mycorrhizae to the rhizosphere, mechanism of root colonization, effect on plant physiology and growth, biofertilization, plant resistance and biocontrol of plant pathogens. This book discusses and goes into detail on a number of topics: the molecular basis of nutrient exchange between arbuscular mycorrhizal (AM) fungi and host plants; the role of AM fungi in disease protection, alleviation of soil stresses and increasing grain production; interactions of AM fungi and beneficial saprophytic mycoflora in terms of plant growth promotion; the role of AM fungi in the restoration of native ecosystems; indirect contributions of AM fungi and soil aggregation to plant growth and mycorrhizosphere effect of multitrophic interaction; the mechanisms by which mycorrhizas change a disturbed ecosystem into productive land; the importance of reinstallation of mycorrhizal systems in the rhizosphere is emphasized and their impact on landscape regeneration, and in bioremediation of contaminated soils; Ectomycorrhizae (ECM) and their importance in forest ecosystems and associations of ECM in tropical rain forests function to maintain tropical monodominance; in vitro mycorrhization of micro-propagated plants, and visualizing and quantifying endorhizal fungi; the use of mycorrhizae, mainly AM and ECM, for sustainable agriculture and forestry.

Download or read book On the Short Waves 1923 1945 written by Jerome S. Berg and published by McFarland. This book was released on 2007-03-28 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: As radio developed in the early 1920s, the focus for most people was the AM band and stations such as KDKA, the first broadcast station. There was, however, another broadcast method that was popular among many early enthusiasts--shortwave radio. As is true today, the transmission of news and entertainment programs over shortwave frequencies permitted reception over great distances. For many in America and beyond, shortwave was an exciting aspect of the new medium. Some still tune the shortwave bands to enjoy the programming. Others pursue broadcasts for the thrill of the hunt. This book fully covers shortwave broadcasting from its beginning through World War II. A technical history examining the medium's development and use tells the story of a listener community that spanned the globe. Included are overviews of the primary shortwave stations operating worldwide in the 1930s, along with clubs and competitions, publications and prizes. A rich collection of illustrations includes many QSLs, the cards that stations sent to acknowledge receipt of their transmissions and that are much prized by long-distance collectors.

Download or read book Down to Earth written by Mansoor Ali and published by WEDC, Loughborough University. This book was released on 1999 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the findings of a Department for International Development (DFID) funded project. It has been written for policy-makers and professional staff of urban government, development agencies and non-government organizations in low-income countries. The book aims to help improve the poor practices of municipal solid waste management that prevail in many low-income countries - a subject that has received comparatively little attention to other aspects of infrastructure such as water supply and transport. It is a complex subject embracing waste collection, transfer, haulage and disposal and its impacts are wide, including for example, effects on environmental health, municipal finance and management, waste reuse, and informal sector employment.
