Penn State researchers found that the addition of iron oxide to gypsum-laden manure, at an equivalent chemical ratio, reduced H2S levels. | Article

New technology a game changer for Wisconsin dairy | A system installed at a 1,400 head dairy produces distilled water and nutrient rich compost by first removing larger solids from the sand bedding, further cleaning the sand, and then treating the liquid stream via centrifugation, ultrafiltration and reverse osmosis. | Article
