This book was released on 1987-08-31 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the occasion of its twenty-fifth anniversary, in 1985, the Netherlands Society for Grassland and Fodder Crops (NVWV) agreed to organize an International Symposium on a topic related to intensive grass and fodder production systems. The theme selected was "Animal manure on grassland and fodder crops: Fertilizer or waste?" This Symposium was organized under the auspices of the European Grassland Federation and held at the International Agricultural Centre in Wageningen from 31 August to 3 September 1987. The problems connected with the disposal of animal waste have received much attention in recent years, especially in regions with intensive animal of animal manure per hectare agricul husbandry. Whereas the production tural land increased strongly, the need for it decreased because of the introduction of cheap inorganic fertilizers which are easier to handle and have a more reliable effect on crop growth. As a consequence, many farmers dispose of animal manure as cheaply as possible, whilst avoiding damage to grassland and crops and paying little attention to effective use of the plants nutrients contained in the manure. Present practices of manure handling and application often lead to environmental problems. The rise in awareness of these problems renewed interest in possibilities to improve the utilization of nutrients from animal manure in crop production. Research on this topic has been stimulated in many countries during the last decade and the aim of this Symposium was to review and assess present-day knowledge.

Download or read book Advances in Agricultural Microbiology written by N.S. Subba Rao and published by Elsevier. This book was released on 2016-06-06 with total page 767 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Agricultural Microbiology is a collection of papers about the progresses in the field of agricultural microbiology. The said papers are contributions of different experts in related fields. The book is divided into three sections. Section A covers topics related to the role of microorganisms in the mobilization of nutrients for plant growth such as the relationship of microbial genetics and biological nitrogen; plant surface microflora and plant nutrition; and developments in grass-bacteria associations. Section B discusses the use of microorganisms in the management of pathogens, pests, and weeds and includes topics such as the microbial control of insect pests; microbial herbicides; and agricultural antibiotics. Section C tackles strategies in bioconversion such as the production of biogas from agricultural wastes; bioconversion of lignocelluloses into protein-rich food and feed; and ethanol fuel from biomass. The text is recommended for biologists and agriculturists who would like to know more about the importance of microorganisms in the field of agriculture.

This book was released on 2013-06-29 with total page 703 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a selection of papers presented to the Fourth Internation~l Symposium on Environmental Biogeochemistry (ISEB), and a conference on Biogeochemistry in Relation to Mining Industry and Environmental Pollution (Leaching Conference), held in Canberra, Aust ralia on August 26-31 and September 3-4, 1979, respectively. The ISEB were established to provide "a forum for uninhibited exchange of information and ideas among the biological, chemical, atmospheric and geolorical scientists working in the common area of biogeochemistry, encompassing soil and other earth sciences as well as the hydrosphere and atmosphere", By linking the fourth ISEB with the Leachin~ Conference the scope of discussions was extended to encompass the application of biogeochemical processes to the mining industry. This wide-ranging philosophy is reflected in the breadth and diversity of the subjects covered in this book. The published papers are expanded versions of those presented at the meetings. They have all been scrutinized by at least one referee in addition to the editors. About 20% of the contributions to the meetings are not included, either because authors did not wish to publish or because the papers were not accepted by the editors.

Available in PDF, EPUB and Kindle. Book excerpt: The study of soil nitrogen has long been an active field, but it was generally pivoted on agricultural and forestry production, and animal husbandry. With the rapid increase in the use of fertilizer nitrogen, more attention has been paid to the rela tionship between nitrogen management and environmental quality and human of soil nitrogen has become more comprehensive with health. In addition, the study the development of related sciences. The quantitative study of the processes in nitrogen cycling and their interrelationships has been an important part of this project and has attracted the attention of scientists allover the world. Nitrogen is one of the most important nutrients for plant growth and the applica tion of fertilizer nitrogen is playing an important role in agricultural production. The annual consumption of fertilizer nitrogen in the world has reached 70 million tons, and China has an annual consumption of more than 15 million tons and is the largest fertilizer nitrogen consumer in the world. However, the efficiency of nitro gen fertilizer is low and losses are large. It is estimated that nitrogen losses from agriculture in our country can be as high as 40-60% of the nitrogen applied. Some of the lost nitrogen enters the atmosphere and contributes to the greenhouse effect and some enters water bodies to pollute the water.

Download or read book Denitrification in Soil and Sediment written by Niels Peter Revsbech and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The formation of atmospheric nitrogen gas by denitrifying bacteria may represent a significant nutrient sink in natural ecosystems. The rate of denitrification has often been difficult to measure in situ, however, and new methodologies should stimulate research on distribution of activity in space and time. The load of fertilizer nitrogen in modem agriculture has led to increasing nutrient reservoirs in recipient subsoils, aquifers, inland waters and coastal seas. By its conversion of nitrate to atmospheric nitrogen, bacterial denitrification is the only biological process to potentially reduce the impact of increasing nutrient loadings by fertilizer nitrogen in the environment. As part of a scientific program set up by the Danish Ministry of Environment to study environment cycling of nitrogen, phosphorous and organic matter (NPO program) in the light of agricultural, domestic and industrial activities, a symposium on DENITRIFICATION IN SOIL AND SEDIMENT was held at the University of Aarhus, Denmark from 6-9 June 19i\9. On the basis of lectures given at the symposium, this book contains a number of invited contributions on the regulation of denitrification activity (control of enzyme synthesis and activity) and measurement of in situ rates of denitrification in terrestrial and aquatic environments (control factors, diel and seasonal variations, etc). Emphasis has been placed on including the recent improvements in methodologies and current understanding of process regulation, however the book also contains examples of integrated research on the significance of denitrification in environmental nutrient cycling.
