- Comment 1) It is the mineral or rock material on and/or from which soils are formed during pedogenesis2) The nature of the parent material strongly influences soil properties such as texture, pH, fertility, and mineralogy. For example, coarse-grained, quartz-rich parent material such as glacial outwash generates soils that are often gravelly and with a coarse (sandy) texture.
