Cunningham
Take home messages<br />
• Small paddocks<br />
• Rotational grazing – good fencing<br />
• Wallaby control<br />
• Plough wider rows<br />
• Spray buffel between rows<br />
• Good preparation of ground<br />
• Don’t count the cost!!!!!<br />
• Use auto steer to for precision rows
The Bad & Ugly<br />
• Rain at the wrong time<br />
• Wallaby damage<br />
• Crusting<br />
• Competition from other crops<br />
• Planting when soil is too moist<br />
• Plant deaths from chemical concentration<br />
• Feed only 6 mths of the year due to frost damage
When all else fails go fishing!!!
