SOIL FAI1ILIES 1. Solonchaks Carpentaria soils occur behind the mangrove frJnge in the littoral areas, and are subject to seasonal marine inundation. Salt encrustation and a highly flocculated surface laer is common in these soils. Soil pH is high t~roughout the profile". The surface crust may be regularly cracked. Vegetation is absent. A typical profil e (Ug5. 2) : HORIZON DEPTH 0-2 abrupt to A12 2-10 grad ua 1 to 10-60 2. All uvial Soil s DESCRIPTION Olive grey (5. c OY 5/2); medium clay; coarse granular crumb; rough ped; dry, moderately strong; pH 8.0 01 ive ( 5;; OY 4/3"); heavy clay; massive; wet and sticky; pH 8.0 01 ive (5.0Y 5/3"); heavy cl ay; massive; wet and sticky; pH 9.0 Saline muds occur under mangroves .. and ~long the tidal creeks and coast line. The soils are distinctly l"ayered, with sticky mud and often with a strong smell of hydrogen sul phide. 3. Li tho so 1 s Skeletal soils occur on all country with slopes exceeding approximately 5% and on ~obourg mainly over11e ferruginous sandstones of block indurated laterjte. Soils are shallow, gravelly and stony with sandy textures dom inant. 4. Calcareous Sands Dune sands occur on relict beach ridges and plains along the coastline of Cobourg Peninsula "b~t in particular the rear dunes and plains of the northern points (e.g. Black Point/Smith Point). A typical profile (Uc1.1): HORIZ ON DEPTH DESCRIPTION A 0-30 Brown (7.5YR- 5/4); coarse sand and shell grit; massive; gritty; pH 9.0 D 30-130+ Layered subsoil of brown gr itty sand with shell fragments; pH 9.0 - 51
