Spring Oats N Advice

Nitrogen recommendations (kg/ha) for Spring Oats based on soil N index and crop yield potential (t/ha)*

To convert kg/ha to units/ac multiply by 0.8

* Proof of higher grain yields is required for an additional 20kgN/ha for each one tonne above a base grain yield of 6.5t/ha

* Higher grain yields shall be based on the best yield achieved in any of the 3 previous harvests, at 20% moisture content

1The table above shows the level of P and K for Spring Oats based on soil P and K index and crop yield potentia.
2Additional P can be applied on the basis of proof of higher grain yields in anyone of the previous 3 years at 20% MC. An additional 3.8 kg P/ha for each extra one tonne above the base yield of 6.5 t/ha.
3 For oats increase/decrease K rates by 15kg K/ha for each tonne of grain increase or decrease in yield grain as shown in the above table.
Always adjust nutrient applications where organic manures are applied
