15 Yellow and brown strongly acidic mottled texture contrast soils on Neogene sediments
| These soils are found on the gently undulating plains, rises or low level plateaux in higher rainfall areas underlain by Neogene sediments (generally sands) which are generally unconsolidated but often have an indurated pan or layer on which the soils have developed. These strongly acidic mottled yellow and brown texture contrast soils are not as prevalent as the other texture contrast soils, however, despite the acidity some of these soils are sodic at depth. Characteristics are similar to other soils on Neogene sediments with pale mottled but strongly structured subsoils and buckshot in the often bleached subsurface horizon sitting on the subsoil. There may be more organic matter and deeper in the surface horizon in the wetter areas. Notable characteristics are texture contrast and strongly acidic mottled subsoil, limiting nutrient availability. |  |
