Series C

Soils included in this series have distinct texture contrasts between hard setting surface soil horizons and moderately to strongly pedal clayey subsoils. Conspicuously bleached A2 ‘subsurface’ soil horizons are present. The uppermost subsoil layer, that is at least 15 cm thick, is mottled and dominantly brown. The soil reaction trend is alkaline.

In the present survey, this series consists of the following soil type:

Type C

Profile Morphology:

Surface Soil - A1 horizon

About 10 cm thick.
Dark greyish brown to dark brown.
Sandy clay loam (occasionally sandy loam).

Surface Soil - A2 horizon

10-15 cm thick.
Greyish brown to yellowish brown (moist); conspicuously bleached near white (dry).
Sandy loam to sandy clay loam.

Subsoil

Mottled brown to yellowish brown and/or yellowish red to reddish yellow. Colour mottling may decrease with depth.
Medium to heavy clay.

Soil Inclusions:

Trace to slight amounts of soft and/or hard CaCO3 occur at about 50 cm depth.

Analytical data for selected depths down the profile:

Depth	pH	Total Soluble Salts	Sodium Chloride	Moisture Retention @ 15-Bar	Moisture Retention @ 1/3-Bar
.	.	%	%	%	%
A	6.9	0.047	*	8.1	14.3
B	8.9	0.139	0.046	28.1	51.5
C	9.0	0.352	0.166	26.8	52.3

* Sodium Chloride contents were not measured and are expected to be very low (based on TSS <0.05%).

Occurrence:

Type C occurs mainly in drainage lines, shallow depressions and some low-flat areas of the undulating plains.
