Management considerations
Medium textured soils (loams) offer high agricultural versatility with very few physical limitations, but remains dependent on any chemical or depth restrictions.
Friable surface soils (and subsoils) occur through the build up of dense organic matter (O2 horizon). Their acidic nature (pH < 5.0) 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). Deficiencies of calcium, potassium and molybdenum are likely.
