Conclusions

• Phosphate is needed close to maize roots to support growth

• Phosphate is a significant potential pollutant

• UK phosphate soil levels mean that inorganic phosphate could be reduced

• Maize fields often receive more phosphate than is required

• New regulations must be observed

• Look at your crop offtake for the whole rotation

• Fully account for phosphate applied via organic manures

• If you have an index of 4 or over your crops do not need phosphate.

• We will continue to trial phosphate and non phosphate alternatives.
