Future Farm Systems Update 31 Oct 2024

 

 

This project compares the productivity, profitability and impact on people and the environment on three farms, being:

  1. Baseline (Current) Farm – Kikuyu & ryegrass based pastures with up to 190 kg N/ha/annum, 3.1 cows/ha
  2. Alternative Pastures Farm – Tall fescue & cocksfoot based pastures, up to 190 kg N/ha, 3.1 cows/ha
  3. Low Emissions Farm – Kikuyu & ryegrass based pastures, designed to reduce methane emissions by 25% and nitrous oxide by 50%, no nitrogen applied, 2.3 cows/ha

 

This project is funded by DairyNZ, MPI (Sustainable Food & Fibre Futures) and Hine Rangi Trust.

CURRENT MANAGEMENT

  • The excellent spring conditions continue with regular showers maintaining high pasture growth.
  • Quality is just starting to fall with seedhead emergence on the Italian ryegrass beginning. We are harvesting more silage today and have dropped a couple more paddocks out for harvest in 2 weeks. Proactive surplus management is our key to maintaining quality and milk production in the next month.
  • High clover levels on the Low Emissions Farm have boosted energy intakes, with these cows milking at over 2 kg MS/c/d since early August.
  • Chicory crops on the Alternative Pastures Farm were sown on 25 October, and pest management is vigilant with high populations of springtail and caterpillars around this season.
  • Calves are all weaned and gone to grazing.
  • Sustain application continues at 60 kg/ha while there is enough moisture.
