B21	10–25	Dark grey (5Y4/1); light clay; subplastic; moderate coarse prismatic, parting to coarse subangular blocky structure; strong consistence dry; moderately sticky consistence wet; very few (<2%) hard carbonate segregations; pH 8.8.
B22	25–50	Dark grey (5Y4/1); heavy clay; subplastic; moderate coarse prismatic breaking down to coarse subangular blocky structure; strong consistence dry; moderately sticky consistence wet; very few (<2%) hard carbonate segregations; pH 9.0.
B23	50–85	Dark grey (5Y4/1); heavy clay; subplastic; moderate coarse prismatic, parting to coarse subangular blocky structure; strong consistence dry; moderately sticky consistence wet; very few (<2%) hard carbonate segregations; pH 9.4; sharp and wavy boundary to:
B24	85–115	Grey (5Y5/1); heavy clay; plastic; coarse lenticular structure (slickensides); strong consistence dry; moderately sticky consistence wet; very few (<2%) hard carbonate segregations; pH 9.6.
B25	115–140	Grey (5Y5/1); heavy clay; plastic; coarse lenticular structure (slickensides); strong consistence dry; moderately sticky consistence wet; very few (<2%) hard carbonate segregations; pH 9.6; gradual boundary to:
B31	140–180	Pale olive (5Y6/3); heavy clay; plastic; coarse lenticular structure (slickensides); pH 9.7.
Management considerations
Cracking clay profile, very high clay percentage Alkaline throughout soil Friable self mulching surface Very high calcium percentage in surface and upper and mid subsoil (to 90cm) Yellow hue profile(5Y) and lighter coloured deep subsoil, poorer internal drainage Subsoil is strongly sodic and salinity increases at depth, particularly below 50cm Very strong consistence when dry, implications for compaction and implement use Landform element, plain: poor site drainage
