Soils NR 200 Unit 2 Formation of Soils From Parent Materials SOIL FORMING FACTORS A. This situation is unfortunate because soil biota are considered the most sensitive indicators of soil quality due to their high responsiveness to changes in environmental conditions (Bastida et al., 2008, Bone et al., 2010, Kibblewhite et al., 2008a, Nielsen and Winding, 2002).
