  • Long-term Effects of Sewage Sludge and Farm Slurriesby J.H. Williams; P. L'Hermite; G. Guidi

    Spon Press 1985; US$ 260.00

    Previous seminars organised by the working party under the auspices of the EEC Concerted Action have been devoted to the evaluation of the nitrogen, phosphorus and organic matter content of sewage sludges, almost invariably over the twelve month period of application. Depending on the type of sludge they have been shown to be useful sources of nitrogen, phosphorus and organic matter for grass, cereals and in land restoration in terms of improving the physical properties of disturbed lands. However, distance from the treatment work severely limits the radius of operation. Whereas it is of value to farmers within reach of the works, the impact which it makes nationally on reducing the annual fertilizer bill is very small. more...

  • Compost Utilization In Horticultural Cropping Systemsby Peter J. Stoffella

    CRC Press 2001; US$ 119.95

    Containing 18 contributions by mostly university-based soil scientists, agronomists, agricultural researchers, resource economists, and many others, this volume provides a thorough review of the use of compost in horticultural cropping systems, as well as of commercial compost production systems; the biological, chemical, and physical processes tha more...

  • The World's Greatest Fixby G.J. Leigh

    Oxford University Press 2004; US$ 35.00

    Tells the story of how humans have used their ingenuity throughout history to maintain soil fertility, and to avoid famine through productive agriculture. This work shows how the development of towns and fixed settlements meant that methods had to be found to maintain the fertility of fields exploited year after year. more...

  • Nitrate, Agriculture and the Environmentby T. Addiscott

    CAB International 2005; US$ 55.00

    There is widespread public concern about the effects of nitrate derived from the use of fertilizers in farming on water quality and public health. But research on nitrate during the past decade has revealed wide discrepancies between public perceptions and reality. more...

  • Waste Composting for Urban and Peri-Urban Agricultureby P. Drechsel; D. Kunze

    CAB International 2001; US$ 110.00

    Rapid urbanization has created a major challenge with regard to waste management and environmental protection. However, the problem can be ameliorated by turning organic waste into compost for use as an agricultural fertilizer in peri-urban areas. This book addresses these subjects. more...

  • Nutrients for Sugar Beet Productionby A.P. Draycott; D.R. Christenson

    CAB International 2003; US$ 120.00

    After a summary of world sugar beet production, this text describes the plant's need for each nutrient and their effects on growth, yield and crop quality. The soil's supply of nutrients is examined as the basis for use of mineral fertilizers, organic manures and foliar applications. more...

  • Soil Fertility Decline in the Tropics, With Case Studies on Plantationsby A.E. Hartemink

    CAB International 2003; US$ 135.00

    It is generally assumed that soil fertility decline is widespread in the tropics. In contrast, perennial plant cover provides better protection for the soil. This book reviews these concepts, focusing on soil chemical changes under different land-use systems in the tropics, including perennial crops, annual crops, and forest plantations. more...

  • Compost Science and Technologyby L.F. Diaz; M. de Bertoldi; W. Bidlingmaier

    Elsevier 2007; US$ 180.00

    Composting is a widely used biological process for the management of some wastes produced in communities and agricultural activities, which have experienced substantial growth during the last few years. Because this and the knowledge of composting has increased, the number of composting facilities has increased tremendously, especially in some European countries. Interest has also increased in several countries in other regions of the world. This book attempts to summarize some of the most important work conducted during the last few years under one cover. The contributions to the publication are made by some of the most qualified professionals in the world and present the information in a clear and objective manner. The readers will find the... more...

  • Soil, Fertilizer, and Plant Silicon Research in Japanby Jian Feng Ma; Eiichi Takahashi

    Elsevier 2002; US$ 170.00

    Silicon (Si) plays a significant role in the resistance of plants to multiple stresses including biotic and abiotic stresses. Silicon is also the only element that does not damage plants when accumulated in excess. However, the contribution of Si to plant growth has been largely ignored due to its universal existence in the earth's crust. From numerous intensive studies on Si, initiated in Japan about 80 years ago, Japanese scientists realized that Si was important for the healthy growth of rice and for stability of rice production. In a worldwide first, silicon was recognized as a valuable fertilizer in Japan. The beneficial effects of Si on rice growth in particular, are largely attributable to the characteristics of a silica gel that... more...

  • Nitrogen in the Environmentby R.F. Follett; J.L. Hatfield

    Elsevier 2001; US$ 275.00

    Nitrogen in the Environment: Sources, Problems, and Management is the first volume to provide a holistic perspective and comprehensive treatment of nitrogen from field, to ecosystem, to treatment of urban and rural drinking water supplies, while also including a historical overview, human health impacts and policy considerations. It provides a worldwide perspective on nitrogen and agriculture. Nitrogen is one of the most critical elements required in agricultural systems for the production of crops for feed, food and fiber. The ever-increasing world population requires increasing use of nitrogen in agriculture to supply human needs for dietary protein. Worldwide demand for nitrogen will increase as a direct response to increasing population.... more...
