fertiliser only in the trials where lime had been applied.
The results indicate that grain yield responses to lime and phosphorus treatments were driven by growing conditions prior to flowering with grain size distribution not affected by the treatments.
Lime also had a greater effect than rotation in regards to soil phosphorus availability and grain yield.
Yield was highest where lime was applied and it appears that phosphorus fertiliser is used more effectively when lime has been applied. T
