HUN99 (Plot 1)

Site: HUN99 (Plot 1)	Land Unit: Follett Dunes and Plains
*Aust. Soil Class.:*

General Land Unit Description:

The majority of this land unit falls south of the Kanawinka fault. This land unit comprises areas with deep sand deposits. The residual landscape is thought to be influenced by the retreat of the Murray Sea which left stranded beach ridges oriented south west–north east. These were subsequently covered by superficial sand sheets in later depositional phases, which formed the landscape seen today.

The major landforms in this land unit are dunes and swales. Podosols and Kurosols or Chromosols are the major soil types found on the dunes and rises. Podosols are soils with a ‘coffee rock’ layer (refer to photograph below). The Kurosols or Chromosols tend to have a deep sandy topsoil over the clay. The common soil types on the swales are black cracking clay (Vertosols) or Grey Sodosols. Some Ferric Kurosols or Chromosols can also occur on the swales or lower slopes of the dunes.

Soil Profile Morphology

A1	0-30 cm	Very dark grey (10YR3/1) loamy fine sand; single grain structure; loose consistence when moderately moist; many medium roots; clear and smooth transition to:
A21	30-80 cm	Light brownish grey (10YR6/2) fine sand; single grain structure; loose consistence when moist; few fine roots; clear and smooth transition to:
A22	80-150 cm	Light grey (10YR7/2) fine sand; single grain structure; loose consistence when moist; no roots observed.
	Subsoil
	150-230 cm	Similar to layer above.
	>230 cm	Cofee rock (Bs) layer, similar to plot 3, but deeper.
Notes: Unfortunately, a collapsing pit prevented assessment of the profile to a greater depth.
