Management considerations
The deep sandy soils (associated with the sand and gravel parent lithology) generally have poor plant water/nutrient holding capacity. The soils are particularly prone to wind, sheet and rill erosion. The upper soil horizons may be hydrophobic (in conjunction with organic coatings) when dried out, taking time to reabsorb moisture. These soils do however drain rapidly. Acid soil pH is often associated with sandy surfaces due the lack of base minerals and may or may not have organic matter (humose or peaty surfaces). This acidic nature restricts the uptake of certain nutrients as well as intolerance for some plant species (due in part to the increasing mobilisation of aluminium and manganese).
