Evaluate Risk and Benefits of Soil Amendments Used in Agriculture

This two-year study analyzed 260 studies spanning 52 years to evaluate the advantages and potential disadvantages associated with the use of biosolids, other soil amendments, and chemical fertilizers. It found that risks associated with biosolids are no greater than — and, in some cases, are less than — the risks associated with the use of other soil amendments in agriculture. This study demonstrated that numerous benefits are associated with the use of biosolids and that known risks can be managed. For all products studied, proper application is the key to optimizing these benefits while also protecting the environment. The report comes with a free 12-page, color companion piece suitable for distribution to stakeholders. Published by WERF. 154 pages. Soft cover.
