Courtesy of USGS Biology, Contaminant Biology Program Because pH is a logarithmic function, one unit change in pH (e.g., 7 to 6) indicates a 10x change in H + concentration in that solution. However, what is actually measured is hydrogen ion activity, not concentration. WebIn general, optimum availability occurs between a soil pH of 6.0 and 7.0 (Brady, 1990 ). Low pH results in lower rates of N mineralization, a process dependent on active, viable microbial populations in the soil. Thus, ammonium accumulation has been shown at low soil pH ( Cornfield, 1952 ).
