Description

A0

0–2

Very dark greyish brown (10YR3/2); silty loam; massive (structureless); common subangular fine to medium quartz gravels; many very fine and fine roots; water repellent; pH 6.0; abrupt and smooth boundary to:

A1

2–50

Strong brown (7.5YR5/6); sandy loam; massive(structureless); very weak dry consistence; abundant medium to coarse quartz gravels; common fine and very fine roots; pH 6.0; gradual and smooth boundary to:

B2

50–90

Yellowish red (5YR5/8); sandy clay loam; very weak dry consistence; abundant fine quartz gravels to quartz stones; few fine and very fine roots; pH 5.5; gradual and smooth boundary to:

C

90–135+

Massive (structureless); strongly cemented quartz gravels and stones.
Management considerations
  • High quartz gravel content, aids drainage, but reduces water holding capacity
  • Acidic, gradational profile over dense often cemented gravel base
  • Nutrient status is low (but proportionally high given low clay content) as is nutrient holding capacity
  • Poor structure, but moderately well to well drained due to low clay content
  • Lower slope topographic position
