New publications: Effects of ivermectin on the diversity and function of dung and soil fauna

The application of veterinary medical products to livestock can affect soil organisms in manure-amended fields and, especially, organisms colonising the dung of treated animals, thereby potentially delaying the degradation of dung on pastures. For this reason, the authorisation process for veterinary medical products in the European Union includes a requirement for higher-tier tests when adverse effects on dung organisms are observed in lower tier toxicity tests. An international research project was performed…

Publication on biosolids applied to agricultural land

Biosolids have well-documented crop and soil benefits similar to other sources of organic amendment, but there is environmental concern due to biosolids-associated pollutants. The present study investigated two field sites that had received biosolids at commercial-scale rates…

Comparison of the dung and soil fauna on ivermectin-treated and untreated meadows as an example of the effects of a veterinary drug

Ecological impacts of land application of biosolids on indigenous soil-dwelling organisms and how it relates to soil function and structure

In a long-term experiment run by Agriculture & Agri-Food Canada, the fate of pharmaceuticals and other substances contained in biosolids are followed after farm-scale application to agricultural land on an experimental field site in Ottawa. In the context of this experiment, ECT follows the development of nematode and enchytraeid communities over several years after the […]
