Biophysical Characteristics of Tropical Peatland

Based on Jenny’s equation (1941) of soil forming factors i.e. S = f(C, R, B, P, T) with the five soil forming factors, the biotic (B) factor of soil formation is the most multifaceted among them. The biotic factor can be grouped into vegetation, microorganisms, animals and human activities. Veget...
