Table 1 Percentage responses citing experience with specific disc seeder limitations.. The trend towards greater adoption of disc opener planter continues to increase as Australian farmers seek more flexibility and robustness from their farming systems... 1. Coulter disc openers - these vertical discs running in the plane parallel to the direction of travel are often used with tyne openers and double disc openers where the coulter is used primarily to prepare the way for seed placement by either cutting residue, doing some soil disturbance (the amount depending on whether it is smooth, bubbled, ripple or wavy, its operating depth and peripheral rotation speed) and/or applying (liquid) fertiliser...

Growers are increasingly moving towards a zero-till system using a disc seeder, which is changing some aspects of the farming system and the recommendations advisers provide to their clients... Disc seeders also allow higher levels of stubble to be retained, particularly at narrow row spacings, which has been a key driver of their adoption... It is important to plan your fertiliser strategy carefully, in many cases separating fertiliser from seed, or top dressing a portion of it in a separate operation...

"The best treatment, reaching over 90 percent emergence, in the Moorlands trial was obtained by adding a shallow operating scooping share ahead of a triple disc seeding system to clear away the top 3-4cm of soil into the inter-row zone and assist with placing seeds into moist soil," Dr Desbiolles said...
