Disc popularity raises need for buyer homework.. Legal and machinery experts are urging grain growers to carefully research the range of disc seeders on the market to make sure the equipment they buy is suitable for their situation... Mr Sulman suggests asking suppliers: for written evidence outlining research data specific to the machine being purchased to assess its suitability for the farming system, soil type and moisture profile; or to sow a trial, or multiple trials, under different seasonal conditions on-farm; or to lease the machine so it can be tested for performance...

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...

Effect of herbicides - Discs are not supported by herbicide labelling at this point so any recommendation would be considered off-label with associated liability... Work is ongoing to consider options for future labelling for herbicide use with discs... Consider timing of seeding to the conditions that will be expected a. Beans and canola sown early into dry stubble will often have less pinning issues because dry, brittle stubble is cut easier b. Cereals planted later into damp stubbles are at risk of pinning because of poor cutting performance i. Pay particular attention to maintenance of the disc as they are not as forgiving as knife-points if improperly maintained...

Technology adoption would be greatly accelerated with detailed knowledge of the factors affecting no-till sowing performance made available to grain growers... The project will underdertake fundamental research aiming to: - understand the mechanics of soil movement and soil throw with narrow point seeding technologies, - improve the performance of disc seeders in heavy soils and stubble conditions... The project will be undertaken by a broad team of researchers collaborating with the Western Australian No-Till Farming Association (WANTFA), the South Australian No-Till Farmers Association (SANTFA) and the Conservation Agriculture Alliance of Australia and New Zealand (CAAANZ), incorporating a national survey on disc seeder performance and issues, fundamental studies of the performance of disc seeders and tine seeders...

One innovative central NSW grower finds building his own machinery has two benefits - it saves money and he ends up with exactly the machine he wants.. Overall, he says the disc seeder was the way to go: "We can sow on lower moisture and I also never feel we are wasting moisture because as soon as you put a tine into this country, it opens right up for moisture to disappear.".. Location: Ungarie, central NSW Rainfall: 338 millimetres Soil type: medium red loam with average pH of 5 Cropping area: 2000 hectares of owned and leased country Crops: wheat, barley, field peas, chickpeas and lupins Average yields: 2 t/ha wheat Tractor: Caterpillar 55, 260hp Sowing equipment: homemade air seeder Spraying equipment: self-propelled boomspray built on a second-hand cotton picker pbrlogo Varieties displaying this symbol beside them are protected under the Plant Breeders Rights Act 1994...

a) Compare the efficacy of various pre emergent herbicides on problem weeds in wheat, barley, field peas and chickpeas, b) Compare crop safety and weed control in both tine and disc seeders, c) Compare crop safety and weed control of various herbicides when applied IBS and PSPE... Twenty six herbicide and herbicide mixtures (plus a control) were applied over wheat, barley, chickpeas and field peas... c) The trials showed a strong relationship where crop safety was enhanced by an average of 10% when a herbicide was applied IBS over PSPE. Some more mobile water soluble herbicides caused up to 30% more damage when applied PSPE...

No pre-emergent herbicide in Australia has on-label recommendations for disc seeders.. The study, conducted by the University of Adelaide and University of South Australia with support from the Grains Research and Development Corporation (GRDC), aims to refine the industry's understanding of the use of disc seeders in conjunction with pre-emergent herbicides and inform future on-label advice... University of Adelaide researcher Sam Kleemann said although growers increasingly recognised the advantages of disc seeders, many pre-emergent herbicides' on-label advice forbids use alongside disc seeders, and chemical companies often won't support the use of disc seeders because of a lack of information around the machinery's impact on crop safety...
