B2	65-80	5.8	4.7	0.08	0.99	0.48	0.58	0.05	0.58

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
