The composition comprises one or more phosphorus-containing acids or salts thereof selected from the group consisting of phosphoric acid, polyphosphoric acid, phosphorous acid, polyphosphorous acid, hypophosphorous acid and polyhypophosphorous acid, and salts thereof. A suspension agent maintains undissolved solids in substantially homogeneous suspension wherein the suspension has a total acid and salt content of about 50% w/w to about 80% w/w. The concentrated fluid phosphorus fertilizer is a stable suspension and when diluted with water a substantially fully soluble fertilizer having acceptable pH for phosphorus uptake is formed.
