Inst.. This book was released on 1995-09-30 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reprinted from Plant and Soil, v.174, nos.1-2 (1995), this volume is devoted to discussions on the role of biological nitrogen fixation (BNF) in agricultural sustainability. Papers presented on BNF in crop forage and tree legumes are augmented with discussion of integrated farming systems involving BNF, soil and N management, and recycling of legume residues. BNF by non-legumes is discussed and attempts to transform cereals into nodulating plants are critically reviewed. Also described are advances in the development of new methodologies to understand symbiotic interactions and to assess N-2 fixation in the field; means of enhancing BNF through plant and soil management; breeding and selection; problems encountered in exploiting BNF under farmers' field conditions; and promising approaches to improve BNF exploitation.

Download or read book Tropical Agroforestry written by Alain Atangana and published by Springer Science & Business Media. This book was released on 2013-10-29 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry is recognized as a sustainable land-use management in the tropics, as it provides environmental-friendly ecosystems; it also provides people with their every day need for food and cash. Since the recognition of agroforestry as a science, curricula have been developed for agroforestry programs for undergraduate and graduate trainings in Universities. Therefore, there is an urgent need to develop and make available educational material. This textbook strives to provide up-to-date information on tropical agroforestry to serve as educational material in the tropical context. The authoritative textbook of Nair (1993) on agroforestry was published 18 years ago, and before the advent of tree domestication, an important agroforestry practice today. In addition, many other research activities, such as carbon sequestration and integrated pest management, have been included in the agroforestry agenda. This textbook is intended for agroforestry students, teachers, and practitioners.

Book excerpt: NOW A MAJOR MOTION PICTURE • NATIONAL BESTSELLER • NAMED ONE OF THE BEST BOOKS OF THE YEAR BY PEOPLE AND USA TODAY • A NEW YORK TIMES NOTABLE BOOK Nobody blows smoke like Nick Naylor. He’s a spokesman for the Academy of Tobacco Studies–in other words, a flack for cigarette companies, paid to promote their product on talk and news shows. The problem? He’s so good at his job, so effortlessly unethical, that he’s become a target for both anti-tobacco terrorists and for the FBI. In a country where half the people want to outlaw pleasure and the other want to sell you a disease, what will become of Nick Naylor?
