This book was released on 2004-06-09 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effects of pesticides on soil fauna: Development of ecotoxicological test methods for tropical regions The impact of pesticides on the soil system is an issue of great concern. In the tropics, the environmental risk of pesticides is assessed using methods designed for temperate regions. This pioneer study shows that the toxicity of pesticides (here: two fungicides and an insecticide) measured under tropical conditions, e.g., higher temperature and different test species, can differ greatly from that determined for temperate conditions. Thus, a risk assessment of pesticides for tropical ecosystems based on existing toxicological data from temperate regions alone is not considered sufficient. Additional, adapted tests must be developed for tropical conditions.

Download or read book Ecotoxicology of Soil Organisms written by Herman Eijsackers and published by CRC Press. This book was released on 1993-12-09 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive examination of all aspects of the ecotoxicology of soil organisms. The book explains how contaminants reach the soil, traces their transport through the soil, and then moves on to examine the effects of contaminants on different groups of soil organisms (e.g., microorganisms, micro- and mesofauna, larger soil animals including vertebrates). The book also considers food chain transfer and discusses risk assessment procedures that are specific to soil conditions. Ecotoxicology of Soil Organisms is the only book to take such a sweeping approach toward soil ecotoxicology.
Download or read book The Importance of Soil Organic Matter written by Alexandra Bot and published by Food & Agriculture Org.. This book was released on 2005 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter - the product of on-site biological decomposition - affects the chemical and physical properties of the soil and its overall health. Its composition and breakdown rate affect: the soil structure and porosity; the water infiltration rate and moisture holding capacity of soils; the diversity and biological activity of soil organisms; and plant nutrient availability. This document concentrates on the organic matter dynamics of cropping soils and discusses the circumstances that deplete organic matter and their negative outcomes. It then moves on to more proactive solutions. It reviews a "basket" of practices in order to show how they can increase organic matter content and discusses the land and cropping benefits that then accrue.--Publisher's description.
Download or read book Herbicides and Environment written by Andreas Kortekamp and published by BoD – Books on Demand. This book was released on 2011-01-08 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herbicides are much more than just weed killers. They may exhibit beneficial or adverse effects on other organisms. Given their toxicological, environmental but also agricultural relevance, herbicides are an interesting field of activity not only for scientists working in the field of agriculture. It seems that the investigation of herbicide-induced effects on weeds, crop plants, ecosystems, microorganisms, and higher organism requires a multidisciplinary approach. Some important aspects regarding the multisided impacts of herbicides on the living world are highlighted in this book. I am sure that the readers will find a lot of helpful information, even if they are only slightly interested in the topic.

Download or read book The Future Role of Pesticides in US Agriculture written by National Research Council and published by National Academies Press. This book was released on 2000-11-02 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although chemical pesticides safeguard crops and improve farm productivity, they are increasingly feared for their potentially dangerous residues and their effects on ecosystems. The Future Role of Pesticides explores the role of chemical pesticides in the decade ahead and identifies the most promising opportunities for increasing the benefits and reducing the risks of pesticide use. The committee recommends R&D, program, and policy initiatives for federal agriculture authorities and other stakeholders in the public and private sectors. This book presents clear overviews of key factors in chemical pesticide use, including: Advances in genetic engineering not only of pest-resistant crops but also of pests themselves. Problems in pesticide useâ€"concerns about the health of agricultural workers, the ability of pests to develop resistance, issues of public perception, and more. Impending shifts in agricultureâ€"globalization of the economy, biological "invasions" of organisms, rising sensitivity toward cross-border environmental issues, and other trends. With a model and working examples, this book offers guidance on how to assess various pest control strategies available to today's agriculturist.

Download or read book Environmental Chemistry of Herbicides written by Raj Grover and published by CRC Press. This book was released on 1988-03-31 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference book deals with the physico-chemical principles and processes controlling the behavior of herbicides in the soil environ-ment and gives a concise, critical account of techniques associ-ated with each subject matter. It summarizes and tabulates data on herbicides by class or group and provides predictive modeling of their behavior with validation of the models from field data. The in-formation makes the reader fully aware of environmental issues rel-evant to herbicide use in agriculture, and allows more reliable and efficient recommendation of herbicide uses. Summaries and con-clusions suggesting gaps in information and potential areas of fu-ture research are also featured. The text is designed for weed sci-entists, environmental chemists and engineers, soil scientists, and those who are responsible for recommending as well as regulating the use of herbicides in agriculture. Soil Aspects Covered Include: ? Adsorption and bioavailability ? Diffusion and mass flow ? Transport in surface run-off ? Evaporation ? Dissipation ? Transformations
Download or read book Interaction of Herbicides and Soil Microorganisms written by Boyce Thompson Institute for Plant Research and published by . This book was released on 1971 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of microorganisms with specific degradative capacities into the soil was shown to be a possible means of ridding the soil of contaminating chemicals. An investigation of the interactions of soil microorganisms and several groups of herbicidal compounds, primarily chlorinated derivatives, was made. In pure culture and in soils the addition of 2,3,5,6-tetrachloroterephthalate (DCPA) had little effect upon bacterial growth, and several microorganisms appeared to use the herbicide as a carbon source. The encouragement of the soil microflora by the addition of nutrient broths resulted in a reduction of toxicity to plants of a number of herbicides. Isopropyl N-phenylcarbamate (IPC) degrading organisms, when added to soil, accelerated the degradation of IPC and related compounds. A membrane 'biologicalilter' device for reducing waterborne biodegradable pollutants was also demonstrated using these organisms.
