In a stinky Science development, researchers have discovered that using alternative types of fertilizers can cut back on greenhouse gas emissions, at least in one part of the US. Nitrogen fetilizers are often necessary to yielding sufficient crops, but their use leads to the release of nitrous oxide, a major atmosphere enemy. Fertilizer use is one reason an estimated seventy-eight percent of America’s nitrous oxide emissions come from agriculture. But scientists have compared those emissions with newly developed fertilizers formulated with “controlled release” polymer-coated…
