Soil Disinfestation considers the effectiveness and necessity of soil disinfestation, while exposing the dangers of various treatments and the ways to overcome them. The book serves as a collection of heterogeneous articles written by a number of research workers in the field of soil science and microbial ecology. The book is divided into five sections and comprised of 15 chapters that cover the general aspects of standard, physical, chemical, and biological soil disinfestation and the fate of pesticides in the soil. The book discusses the causes and consequences of soil contamination and detection methods. The factors that influence the efficacy of each treatment and the practical application of commonly used pesticides, such as fumigants and fungicides, are also explained in this reference. Some of the contributors also give a critical retrospect about the subjects with speculation about the trends in soil disinfestation. Microbiologists and research workers in soil science, as well as students and novices in microbiology, pedology, and microbial ecology, will find this book invaluable for their practice and learning.

Modern Trends in Applied Terrestrial Ecology by R.S. Ambasht,Navin K. Ambasht Pdf
Ecology and economics have Greek roots in oikos for "household", logos for "study", and nomics for "management". Thus, ecology and economics should have complemented one another for a proper growth and development without destruction, but, unfortunately, rapid industrialization, lure for fast financial gains, and commercialization activities have led to a widespread surge in pollution load, environmental degradation, habitat destruction, rapid loss ofbiodiversity, sudden rise in rate ofextinction ofmany wildlife and wild relatives of domesticated animals and cultivated cereals and other plants, global climate changes creating global rise in temperature, and CO levels and increased ultraviolet B at ground 2 level. Although these threats to human health have led us to look to ecology for their solutions and guidance for sustainable development without destruction, the industrial and technology houses are looking for alternative methods of development and resource use methods. The two global conferences of the United Nations in 1972 and 1992, and international programs of Man and the Biosphere (MAB), International Biological Program (IBP), International Geosphere, Biosphere program (lGBP), and World Conser vation Union (IUCN), of different commissions, United Nations Environmental Program (UNEP) efforts, Ramsar Conventions (for wetlands), and World Wide fund for Nature (WWF) (for nature in general and wildlife in particular) have focused attention of ecologists, naturalists, governments and Non-governmental organizations (NGOs) toward better conservation.
The Rhizosphere by Elroy A. Curl,Bryan Truelove Pdf
The Plant Root and the Rhizosphere was a major topical feature of the first International Symposium on Factors Determining the Behavior of Plant Pathogens in Soil held at the University of California, Berkeley in 1963. The symposium was edited by K. F. Baker and W. C. Snyder and published under the title Ecology of Soil-Borne Plant Pathogens. Since that time, several other international efforts, either on the root-soil interface specifically or on topics relating to the root environment, have provided"a wealth of valuable information basic to promoting the culture of healthier, more productive plants. For the writing of this book, inspiration has come, in large part, from 10 years of cooperative rhizosphere research in association with leading scientists participating in a regional effort within the southern United States. We have attempted to bring together in this work the major aspects of rhizosphere research and the principles of rhizosphere ecology for the benefit of developing young scientists and technologists, as well as for the established professional researcher and teacher. A prime objective and hope is that this volume might generate ideas that will bring forth new approaches and methodology leading to further advances in our understanding of rhizosphere interactions and their implications for agriculture. ' Because of the enormous complexity of the chemical, physical, and microbiological environment of roots, the methods used by various workers are rarely standardized, but must be devised or modified for each experiment.

Principles and Practice of Managing Soilborne Plant Pathogens by Robert Hall Pdf
This book considers soilborne plant pathogens from four different perspectives. One approach explores the historical, social, and scientific contexts of these pathogens. A second offers a conceptual framework for understanding their biology and control. Another discusses how the interrelationship of principles and practice leads to innovation in management techniques. A fourth section presents studies that investigate recent developments in practical control strategies.
