Note that the common range of soil pH under natural conditions is from 5.0 to 9.0. For each pH change of 1 unit, the concentration of H + changes 10X. So, how much more acidic is

www.canr.msu.eduThe bacteria are active, when the soil is moist and warm. The soil temperature needs to be above 55F. The bacteria are not active in the winter so fall applications of sulfur have little effect on the soil pH next spring. In addition, the soil must not be saturated, or flooded (anaerobic) or the sulfur is converted to hydrogen

Ammonium-nitrogen concentrations of 2–10 ppm are typical. Soil NH 4-N levels above 10 ppm may occur in cold or extremely wet soils, when the soil contains
