Abstract Yellow phosphorus was dissolved in liquid anhydrous NH 3 and evaluated as a P source for corn ( Zea mays L.) and ryegrass ( Lolium multiflorum L.). The composition was phytotoxic and the P was of low plant availability. When the solution was incubated in soil prior to seeding corn, toxicity was less pronounced. The residue following evaporation of NH 3 was also phytotoxic. In a short term study on a fine‐textured soil, corn failed to respond to either toxic compounds or orthophosphate present in the zone of NH 3 injection.
