Different sowing and topdressing options in annual pasture for grazing systems locations
Aims

To compare a range of starter fertiliser and topdress options for pasture production.

Key messages
  • There were good dry matter responses to starter fertilisers at either 16 or 32 kg/ha of P although only certain treatments gave a significant dry matter inrease when raising P rate from 16 to 32 kg/ha. The best dry matter response was from Gree Top which supplied all the nutrients lacking in the soil test report.
  • Potassium seed burn was not apparent possibly due to the relatively wet conditions.
  • Both DAP and Gree Top grew over 70 kg DM/ha/kg P at the lower rate of 80 kg/ha, which supplied 16 kg/ha of P.
  • Only Green Top, Croplift and Superfect+Mo increased yields with increasing rate of application indicating they supplied the lacking nutrient required to make use of the extra P available.
