Hot Topics

Crop LCA, Grassland Eutrophication

Crop LCA. A life cycle assessment (LCA) comparison of two types of manure systems with synthetic fertilizer for corn production were compared in a new Journal of Environmental Quality Study. The total global warming potential was lowest for the synthetic fertilizer, largely due to methane emissions from stored manure (deep pit and anaerobic lagoon systems were compared). More...

Grassland Eutrophication. A University of Minnesota study utilized a worldwide network of grassland research sites (Nutrient Network) to determine if fertilization (intentional or not) was having an effect on grassland ecosystems. The researchers found a strong connection between diversity and stability and that the addition of fertilizer reduced both. More... | Journal Nature abstract...
