Management considerations
- The surface soil is strongly acid and a response to lime would be expected.
- The surface soil has a very low inherent fertility (based on the sum of the exchangeable basic cations). Such strongly leached soils are also likely to be naturally deficient in nitrogen, phosphorus, sulphur and potassium
