Hydrolytic degradation of the condensed phosphates of fertilizer‐grade calcium metaphosphate (CMP) in soils involves several steps, including formation of a dense, viscous liquid from the vitreous portion of the CMP. Experiments indicate that the rate‐controlling step in the early stages of transformation of condensed P to orthophosphate in soils treated with solid particles of CMP was the degradation of the viscous liquid and not the hydrolysis of the condensed P in the solution derived from the viscous liquid.
