Trial location(s) Port Broughton, SA
Wind speed in varying stubble heights locations
Aims

To observe and record what impact varying stubble heights have on wind speed and therefore soil erosion and crop vigour

Key messages

Stubble height can have a significant impact on wind speed close to the soil surface. This can increase soil erosion in vunerable environments (sand hills).
