That means that the firm is engaged in every step of the process, from mining phosphate in Florida and producing nitrogen to packaging and selling its fertilizers to commercial farmers around the world.Fertilizer has been an attractive business in the last few years, buoyed by rising agricultural commodity prices and continued subsidy checks coming to farmers who grow fertilizer-intense crops like corn.
