* All rates should be reduced by 1/3 where the crop is to be harvested by grazing because of recycling through manure and urine.

1) First application to be made prior to May 10.
2) Second application to be made after the first cut.
3) Third application to be made only if there is reasonable assurance of a third cut.

The fertilizer rates in this table are designed to produce highest economic yields when accompanied by good or above average management. Research data show that higher rates will occasionally produce higher yields but that these increases in yield are likely to be small and uneconomic.

Approved: Ontario Soil Management Research and Services Committee (June 2007).
