Key messages
Crop nitrogen requirements should be applied at or before sowing as poor spring conditions can reduce crop responses to topdressed nitrogen.
When drilling nitrogen with the seed, rates should not exceed 25 kg/ha (7" rowing spacing).
Grain protein levens under 10.5% indicate crop yields are below thier optimum potential - apply additional nitrogen.
