Aims
To determine the effect that urea and GranAm (SOA), deep banded at different rates, has on canola establishment.
Key messages
Applying urea with the seed, even deep banded, can affect establishment and slow growth and development. There was no advantage in applying N at sowing (deep banded). The effects of seed burn on canola are much greater on sandier soils than clay. Dry soils are also more susceptible than wet soils: if applying up-front N, rates should not exceed 10kg N/ha (22kg/ha urea) on 30cm spacing, and seed should be separated by at least three to four centimetres from the nitrogen fertiliser.
