Although surface soil (approximately the top 4 to 6 inches) pH is generally similar in Montana and Wyoming (pH 6.5-8.0), it can range from 4.5 to 8.5, causing considerable fertility and production challenges at these extremes. The primary decomposers (bacteria and fungi) release extracellular hydrolytic enzymes into their immediate environment and these catalyze organic matter decomposition (Berg and McClaugherty, 2008).
