Meeting Abstract. 1999 ASA, CSSA, SSSA, Annual Meeting. October 31-November 4, 1999, Salt Lake City, Utah.Interpretive Summary:
                                Technical Abstract: Soils with higher P sorption capacity lose less soluble reactive P to the water environment.  The P sorption capacity of soils can be increased by addition of Fe(OH)3 or Al(OH)3, as well as by Ca compounds such as limestone and gypsum.  These compounds are the natural chemical components which make up the P sorption capacity of soils.  Many of these compounds  are present in a typical waste floc generated by the chemical neutralization of acid mine drainage (AMD).  This paper will discuss the effect of different AMD neutralization chemicals on floc mineralogy and the resulting P sorption capacity in the water and soil environment.  The P sorption capacity varied with the chemical used to neutralize the AMD from about 90 to 130 mg P/g AMD floc in order of increasing P sorption capacity for flocs neutralized with CaCO3
