The agricultural value of sewage sludges is well known and a lot of published data has demonstrated the positive effects of sludge appli cations on plant growth and yield. These effects are probably due mainly to the nitrogen and phosphorus content of sewage sludges. But, as sludges are more organic than mineral, we can expect an effect of the organic matter added to the soil on soil fertility. Certainly, in the future, landspreading of sludges will be regulated, taking into account pollution hazards for waters (excess of nitrogen and phosphorus supply compared to plant needs and soil storage capacities) and for soils (excess of heavy metals supply and build up in soils). There will be regulations fixing what low level of sludges may be spread each year, decreasing their comparative value with respect to mineral fertilizers. In this eventuality, the organic value of sludges will take on a greater importance and several questions arise : - what is the lowest amount of sludge to be spread to have an immediate effect on soil physical properties? - are sludges effective on soil physical properties when spreading repeated low amounts? On the other hand, organic matter and soil biology are closely linked and there are few data on the possible effects - beneficial or detrimenta- on soil organisms.

Anaerobic digestion has no effect on the quantity of the waste treated, but it affects its quality and its usefulness as fertilizer. This conference proceedings collection of twenty papers delves into the issue.

This book reviews the practice of reclaiming treated municipal wastewater for agricultural irrigation and using sewage sludge as a soil amendment and fertilizer in the United States. It describes and evaluates treatment technologies and practices; effects on soils, crop production, and ground water; public health concerns from pathogens and toxic chemicals; existing regulations and guidelines; and some of the economic, liability, and institutional issues. The recommendations and findings are aimed at authorities at the federal, state, and local levels, public utilities, and the food processing industry.

Sewage sludge application to land is the principal way of deriving a beneficial use for sludge by recycling plant nutrients and organic matter for crop production. It is becoming ever more important as other options for the disposal of sewage sludge are diminishing. Agricultural application also provides a cost-effective method of sludge disposal, but it is essential that sludge recycling in agriculture is regulated to minimize potential environmental problems. This book, based on work funded by the Foundation for Water Research, provides an overview of the environmental impact of sludge application to agricultural land and relates it to other accepted agricultural practices. It puts the potential environmental effects into perspective and distinguishes between perceived and real risk. It is a significant contribution to thinking on this increasingly important topic and is relevant to students and researchers in soil, crop and environmental science. It will also be vital for all those involved in the waste and water industries.

This book provides an authoritative overview of emerging pollutants in sewage sludge and soils. It traces the latest research and new trends on the characterization, removal and treatment of such pollutants in urban and industrial sewage sludge and soils. The book covers topics such as antibiotic resistance, fate and environmental impact of contaminants of emerging concern, environmental transmission of human pathogenic viruses and their effect on soil, and the repercussion of various emerging pollutants on biodiversity. It also offers a case study of the epidemiology-based surveillance of SARS-CoV-2 in wastewater and sludge. The book appeals not only to researchers and professionals working with emerging contaminants, but also to policy makers and a broader audience interested in learning more about the effects of these contaminants in human and environmental health.

This book is devoted to sewage sludge, its sustainable management, and its use and implications on soil fertility and crop production. The book traces the main chemical and biological properties of sewage sludge, and covers topics such as sewage sludge biostabilization and detoxification, biological and thermochemical treatment technologies, emerging nutrient recovery technologies, the role of microorganisms in sewage sludge management, and the sustainable use of sewage sludge as fertilizer in agriculture. The book offers a valuable asset for researchers, scholars and policymakers alike.
