Organic farming stimulates eutrophication more than conventional agriculture
For[edit | edit source]
- According to Our World in Data, "the pollution of ecosystems with nutrients from organic farms are often higher than conventional farms, leading to higher eutrophication and acidification potential." In a meta-analysis of results of published organic-conventional comparisons across 742 agricultural systems over 90 unique foods, eutrophication potential was found to be higher in organic methods across all 5 food groups studied. The researchers Clark and Tillman found that "organic systems have 37% higher eutrophication potential (p = .0383; n = 20) ... than conventional systems per unit of food."
- A 2006 study found that eutrophication impacts are in some cases higher from organic production than they are from conventional production.
Against[edit | edit source]
- A 2006 study that found that organically fertilized fields "significantly reduce harmful nitrate leaching" over conventionally fertilized fields.
