- Observation Phosphorus and sulphur were the major nutrients limiting the growth of clovers on the steepland soils.
- Recommendation About 4 cwt of superphosphate per acre was required initially to remedy phosphate deficiency, and this would also rectify the sulphur deficiency.
- Recommendation Superphosphate should be applied in the spring because of the very low sulphur retention capacities of the soils.
- Intervention effect Initial responses to lime were small and would not be economic.
- Observation Molybdenum was not required in the development of these soils.
