Soil Formation 7Many parent materials are residual and formed in place from some kind of bedrock, like limestone, shale, or sandstone. This material is called residuum (rehÂ­zijÂ­you-um). The kind of bedrock influences the texture of the soil.he characteristics of the soil are determined by the type of parent material, the organisms (plant and animal life on and in the soil), the climate under which the soilÂ­forming factors were (and are presently) active, the topography, and the length of time that the forces of soil formation have been active.
