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.
- Mechanism Rainfall-dependent potassium and sulfur leaching made deficiency-related pasture production decreases unpredictable.
- Recommendation The authors recommended annual potassium and sulfur fertilizer and tissue testing to improve their management.
