Phosphate fertilizer value of paper mill residuals.APPLICATION: The results of this study may help mills evaluate the value of applying mill wastewater residuals to soil. New federal strategies to limit surface water phosphorus phosphorus (fŏs`fərəs) [Gr.,=light-bearing], nonmetallic chemical element; symbol P; at. no. 15; at. wt. 30.97376; m.p. 44.1°C;; b.p. about 280°C;; sp. gr. 1.82 at 20°C;; valence −3, +3, or +5. loading from agricultural fields may affect many paper mills that are beneficially land-applying wastewater treatment residuals. The phosphate fertilizer value of five paper mill residuals was evaluated in long-term incubation incubation /in·cu·ba·tion/ (in?ku-ba´shun) 1. the provision of proper conditions for growth and development, as for bacterial or tissue cultures. 2. studies to develop data for nutrient nutrient /nu·tri·ent/ (noo´tre-int) 1. nourishing; providing nutrition. 2. a food or other substance that provides energy or building material for the survival and growth of a living organism. planning to address the federal strategies. In four of the five paper mill residuals evaluated, the phosphate fertilizer value was substantially lower than commercial fertilizer. By Steven J.
