Synthetic Fertilizers Disrupt Carbon-Capturing Ability of Salt Marshes

Salt marshes, areas of coastal grassland regularly flooded by saltwater, provide a major global service by sequestering and storing carbon in the form of organic matter. However, research finds that nitrate from synthetic fertilizers found in agricultural runoff could change the microbial composition of the salt marshes to encourage organic matter decomposition and, therefore, carbon release versus capture. The study, “Nitrate addition stimulates microbial decomposition of organic matter in salt marsh sediments,” was published in Global Change Biology.  Read more....
