Responsive farming using VRT: strip grazing barley locations

To provide early feed for stock in autumn, a time of year when pastures haven’t established properly, and get ewes and lambs out of the confinement feedlot and onto good quality feed as soon as possible.

Key messages
  • In 2009 47 ha of barley sown for feed at the break of the season sustained 300 ewes and lambs for 3 months during the period of late autumn-winter, a traditional period of pasture deficit.
  • Hay freezing the forage crop ensures grass weeds are controlled.
  • Use of strip grazing better utilises feed on hand and helps control erosion (especially around watering points).
