Soil-phosphorus after drought
Released/reviewed: Dec 2006
Key points discussed in this article include the following:
- The effect of residual phosphorus was strongest where no new phosphorus was applied in the recovery year.
- When phosphorus was applied in the recovery year, there were only small effects of residual phosphorus from the drought year.
- Some reduction of phosphorus rates is possible in the recovery year.
- Sowing time is the only opportunity to effectively apply phosphorus.
- Maintain recommended rates of phosphorus in the second year after drought.
