Monoammonium phosphate (MAP) is a widely used source of phosphorus (P) and nitrogen (N).* It's made of two constituents common in the fertilizer industry and contains the most phosphorus of any common solid fertilizer. Production. MAP's manufacturing process is relatively simple. While there are multiple methods, two common ways include:
