Stony soil conditions represent a significant farming area in the Mallee. The success of seeding in stony soils depends on the ability of the seeding system to maintain sowing depth uniformity under high tripping frequency and intensity.
Therefore, using the right seeding system for prevailing soil conditions can optimise crop establishment and lead to increased yield response in these traditionally lower yielding areas (Figure 1).
The key points to consider are:
• Optimising seeding depth;
• Minimising paddock roughness;
• Point wear and durability issues; and
• Flexibility with contour following seed boots.
