During the 4th ESA-Congress, held in the Netherlands, 7-11 July 1996, a new perspective for agronomy emerged. Various contributions demonstrate the need for a new role of agronomy and its tools. In recent decades, agriculture has evolved from an activity with mainly productivity aims, into an issue conciliating environmental, agricultural, and economic and social objectives. Placing agriculture in such a broadened perspective requires a different agronomy, with new tools and approaches at a range of aggregration levels. It calls for detailed knowledge concerning the functioning, productivity and ecological relationships of agricultural plants and crops. In addition, it calls for a constant update and synthesis of existing and newly generated knowledge, the design of new ideotypes and genotypes, new production technologies, cropping systems, farming systems and agro-ecological land use systems. This proceedings book presents a set of case studies illustrating the various agronomic tools that can be used for specific agronomic questions. The case studies are grouped in sections illustrating relevant subquestions in developing an agriculture with broadened objectives. The book starts with an introductory paper on the role of agronomy in research and education in Europe. The second section deals with agricultural land use, food security and environment. This is followed by a set of papers describing experimental research and modeling approaches used to design new ideotypes of crops, including physiological properties in relation to growth factors such as radiation, CO2, temperature and water. Sustained soil fertility directly links to nutrient cycling and soil organic matter. A selected set of papers addresses the improvements in resource use efficiency and as such their contribution towards economic, environmental and agricultural objectives. The final section addresses the design of integrated and ecological arable farming systems. It highlights the role of prototyping interaction with leading-edge farmers, as promising tools to design, implement and test new farming systems. It is hoped that the activities of the European Society for Agronomy and the Proceedings of its 4th Congress will stimulate to serve the new perspectives of agronomy, i.e. to adopt ecological principles, to optimally manage the use of resources and to meet social and economic objectives.

Agricultural nutrients are a possible pollutant of (ground)water bodies.For prevention and control purposes, the European Nitrate Directive (91/676/EC) was issued, which was implemented in The Netherlands by means of the Mineral Accounting System (MINAS). MINAS tracks nutrient flows on farms and taxes farmers with high nutrient surpluses. The taxes are such, that MINAS can pose a threat to the financial viability of individual farms. In order to prevent taxation, farmers will have to alter nutrient management on their farm in an economically sound manner.To assess the (financial) feasibility of the MINAS-surplus standards a project called 'Farm Data in Practice' (Project Praktijkcijfers in Dutch) was initiated by the Dutch government in co-operation with farm organisations. The research presented in this thesis describes an empirical analysis of the relationship between farm and farmer characteristics, the way nutrients are managed on the farm, and the financial consequences, based.

Grassland Productivity And Ecosystem Services written by Gilles Lemaire and has been published by CABI this book supported file pdf, txt, epub, kindle and other format this book has been release on 2011 with Science categories.
This book contains 28 chapters with emphasis on the interactive nature of the relationships between the soil, plant, animal and environmental components of grassland systems, both natural and managed. It analyses the present knowledge and the future trends of research for combining the classical view of grasslands, as a resource for secure feeding of an increasing human population, with the more recent perspective of the contribution of grasslands to the mitigation of environmental impacts and biodiversity erosion as consequences of human society activities. The chapters are organized within five sections dealing with the different functions and the main ecosystem services expected from grasslands: (i) domestic herbivore feeding and animal production; (ii) the regulation of biogeochemical cycles and its consequences for the environment; (iii) dynamics of biodiversity hosted by grasslands; (iv) integration of grasslands within sustainable animal production systems; and (v) interactions of grassland areas with other land use systems at the landscape level.

Nutrient imbalances have a substantial impact on the productivity and sustainability of agroecosystems worldwide. Fertilizer and manure use, atmospheric deposition, international transportation of produce, solute and gas emissions and soil erosion have all contributed to deficits and surpluses, which in some areas have reached alarming proportions. This book describes and explores the latest concepts of the causes of nutrient imbalances, including the importance of different spatial scales, and examines ways to quantify and manage nutrient stocks, the increasing amount of legislation and the urgent need for the development of integrated nutrient management technologies. Nutrient Disequilibria in Agroecosystemsalso includes case studies, from fish farms in eastern Asia to nutrient flow monitoring in Kenyan tea/maize farms, the dairy sector in New Zealand and ecological farming in Switzerland, the future for global-level research in soil fertility management and nutrient flow analysis. This title should enhance research and the adoption of (inter)national policies on soil fertility maintenance with its global, multi-scale, multi-disciplinary approach.

Focusing on the different types of grassland farming and their impact on the environment, Environmental Impacts of Pasture-based Farming takes a broad and interdisciplinary view of the subject. The text is organized into two sections, the first addressing issues facing environmental quality, namely soil, water and air quality and socioeconomic impacts. The second section offers commentary on how the different pastoral sectors influence environmental issues. With highly tuned farm productive systems comes the risk of environmental impacts, and the purpose of this text is to highlight the areas with which these risks are associated and how best to mitigate them. While drawing attention to potential problems, chapter authors always remain conscious of the socio-economic needs of land users and the increasing world population and keep in mind that intense mitigation may be too restrictive on the farming system. This book takes an unbiased approach to improving management of grazed land and incorporates research from environmental science, agriculture, soil science and ecology.

In order to meet increasing global demand for meat and animal by-products increasingly intensive animal production is necessary. Creating a sustainable system in animal agriculture that works in different production environments is a major challenge for animal scientists. This book draws together themes on sustainability that have emerged as the most pressing in recent years. Addressing practical topics such as air quality, manure management, animal feeds, production efficiency, environmental sustainability, biotechnology issues, animal welfare concerns, societal impacts and an analysis of the data used to assess the economic sustainability of farms.

Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.
