Ledcourt Series

Soils included in this series have distinct texture contrasts between soft ‘non-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 red. The soil reaction trend is neutral.

In the present survey, this series includes one soil type and one phase.

Ledcourt Sandy Loam (LE sl)

Profile Morphology:

Surface Soil - A1 horizon

About 10 cm thick.
Reddish brown to greyish brown.
Sandy loam to sand.

Surface Soil - A2 horizon

About 20 cm thick.
Light reddish brown to yellowish brown (moist), conspicuously bleached near white (dry).
Sand to sandy loam.

Subsoil

Mottled reddish brown, red or yellowish red. Secondary colours include grey, brown and yellow.
Heavy clay to sandy heavy clay.

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	6.5	0.013	*	1.6	4.5
B	7.1	0.093	0.042	20.5	38.2
C	6.3	0.072	0.064	16.6	31.6

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

Occurrence:

Ledcourt Sandy Loam is usually found on the sandy areas formed in the flood plains.

Phases:

Deep surface:

The overall depth to the clayey subsoil is about 60 cm (range 35-140 cm).
A2 horizons comprise about 75% of the surface soils.
Occurs mainly on sand sheets, dunes and sand rises formed in the river flood plains.
