Other claims from this paper (9)

Recommendation Tissue testing was needed with soil testing to confirm nutrient management decisions.
Method / resource Soil pH testing reliably identified paddocks needing lime and monitored liming.
Method / resource Soil phosphorus testing reliably indicated when phosphorus fertilizer was required.
Recommendation No phosphorus fertilizer was needed above the soil-specific critical soil-test phosphorus value.
Observation Plant tissue testing indicated adequate phosphorus for ryegrass production when no phosphorus was applied.
Method / resource Soil testing could not determine which paddocks required potassium fertilizer.
Method / resource Soil testing could not determine which paddocks required sulfur fertilizer.
Recommendation The authors recommended annual potassium and sulfur fertilizer and tissue testing to improve their management.
Recommendation The authors recommended annual soil pH and soil-test phosphorus reporting, with P-buffering index, organic carbon and conductivity every 3–5 years.
