February 2011 153.3.1 Shallow (Rocky) SoilsThe rocky soils are generally shallow and overlie an impeding layer such as hard rock orweathering saprolite. These soils are not suitable for cultivation and in most cases are only usableas light grazing. The main soil forms found in rocky soils were Mispah and Glenrosa, each form isdescribed below.Mispah soil formThe Mispah soil form is characterised by an Orthic A – horizon overlying hard rock. Mispah soil ishorizontally orientated, hard, fractured sediments which do not have distinct vertical channelscontaining soil material. There is usually a red or yellow-brown apedal horizon with very loworganic matter content. Please refer to Figure 3-4 for an illustration of a typical Mispah soil form.Glenrosa Soil FormFigure 3-4: Mispah soil form (Soil Classification, 1991).The Glenrosa soil form is a combination of an Orthic A horizon overlying a lithocutanic B horizon asindicated in Figure 3-5 below. A lithocutanic B has several characteristics that separate it fromother horizons, namely:• It merges into the underlying weathering rock;• Has a general organisation in respect of colour, structure or consistency that has distinctaffinities with the underlying parent rock;ZITHOLELE CONSULTING

The LithocutanicB is described in the Glenrosa soil form above, while the Melanic A horizon is characterised bybeing a dark coloured, well structured topsoil horizon that does not have large amounts of organiccarbon or swelling clays.ZITHOLELE CONSULTING
