Watch your speed when sowing sub-tropical grasses locations
Aims

To determine whether successful establishment of sub-tropical grasses is affected by sowing speed

Key messages
  • Sowing at 5 km/hr gave significantly higher seedling establishment densities than sowing at 10 km/hr and 15 km/h.
  • It was most noticeable that the 15 km/h plots had the most soil disturbance.
