One of the great myths in the agricultural industry is that being able to sow crops while retaining stubble is largely an engineering issue, according to Nigel Wilhelm of the South Australian Research and Development Institute. "This is simply not the case;' Dr Wilhelm told participants at the recent Cropping Research Update at Birchip, supported by the Birchip Cropping Group and growers through the GRDC. "Seeders and cultivators already exist that will handle any amount of any type of stubble. For example, no-till seeders used in the US will seed canol a through 10 t/ha of undisturbed maize stubble on heavy clay soils. The issues to focus on are financing the machinery and. determining which is best suited to your situation."
