TL;DR: An inventory of heavy metal inputs to agricultural soils in England and Wales in 2000 is presented, accounting for major sources including atmospheric deposition, sewage sludge, livestock manures, inorganic fertilisers and lime, agrochemicals, irrigation water, industrial by-product 'wastes' and composts.

TL;DR: Following manure spreading to land, E. coli O157, Salmonella and Campylobacter generally survived in the soil for up to one month after application to both the sandy arable and clay loam grassland soils, whereas Listeria commonly survived for more than one month.

TL;DR: In this paper, the authors collected 183 livestock feeds and 85 animal manure samples from commercial farms in England and Wales and analyzed to determine their heavy metal (zinc, copper, nickel, lead, cadmium, arsenic, chromium and mercury) contents.

TL;DR: The model can be used to predict the likelihood of wheat grain Cd exceeding the new European Union foodstuff regulations on the maximum permissible concentration of Cd under different soil conditions, particularly in relation to the existing Directive and the proposed new Directive on land applications of sewage sludge.

TL;DR: In this article, the authors argue that a whole-farm perspective taking side-effects and on-farm interactions into account is needed to determine the cost-effectiveness of strategies to mitigate pollution from livestock manure management.
