Book Description
The presence - or absence - of soil organic matter (SOM) has important implications for agricultural productivity. It could also have significant implications for global climate due to its role as a source/sink of carbon. Therefore, it is important to understand the issues related to the accumulation or loss of SOM, to use what we have learned from experiments to make sound decisions about soil and crop management, and to test models and future concepts concerning SOM management. A database is included with the book, presenting tabular data for 34 sites in North America. Soil Organic Matter in Temperate Agroecosystems discusses all of these issues and more, answering such questions as:

The Pesticide Question
Author: David Pimentel
Publisher: Springer Science & Business Media
ISBN: 0585369739
Category : Science
Languages : en
Pages : 444
Book Description
Pesticides have contributed impressively to our present-day agricultural productivity, but at the same time they are at the center of serious concerns about safety, health, and the environment. Increasingly, the public wonders whether the benefits of pesticides - `the perfect red apple' - outweigh the costs of environmental pollution, human illness, and the destruction of animals and our habitat. Scientists and government officials are suspected of promoting commercial interests rather than protecting human welfare.

Agricultural Ecology and Environment
Author: B.R. Stinner
Publisher: Elsevier
ISBN: 0444597956
Category : Technology & Engineering
Languages : en
Pages : 645
Book Description
The increased use of chemical fertilizers and pesticides in crop production has adversely affected both the environment and the agricultural economy. Not only has it led to environmental pollution, but also the increasing costs of chemical inputs and the low prices received for agricultural products have contributed to economic unprofitability and instability.The International Symposium on Agricultural Ecology and Environment was organised in order to discuss ways of achieving the goals of economically and environmentally sustainable agriculture. It is apparent that a truly multidisciplinary effort is required and for this reason the meeting was attended by authors from many different disciplines and geographical locations. Although their papers reflect a wide diversity of agroecosystem types and examples, several common themes emerge: the increased importance of biotic control of ecosystem processes in lower input systems; the key role of soil organic matter in stabilizing nutrient cycling; the importance of agricultural landscape diversity and complexity; the importance of studying ecological processes in natural and agricultural ecosystems; the critical need to integrate socio-economic and ecological approaches.
