Soil mixing such as rotary spading often proves an excellent clay incorporation method and offers opportunities for simultaneous incorporation of soil improvers such as lime or gypsum... The paired row seeding boots gave the highest yield response over knife points with nearly a 1t yield increase on the pale deep sand and a 650 kg/ha yield increase on the sandy gravel... Using rounded or 'V'-shaped press-wheels can minimise the risk of furrow collapse and infill and also prevent the furrow side walls being ripped up, which can occur with more rectangular shaped press-wheels creating a tumbling mass of soil behind the press wheel and poor product placement...

Mitigation (annual management) of non-wetting soils by no-till furrow sowing can often be improved by: adding wings to points or boots sowing close to the previous row using banded wetter, especially with knife points using better wetter formulations on dry soil.. The researchers say this would provide greater annual whole-farm profit, assuming the whole farm is moderately water repellent and dry sowing is commonly used... "For growers on moderately repellent yellow sand at East Binnu, a lot of money could be spent on claying or blanket application of a wetting agent; the trial showed this would likely result in wasted money, unless the more effective methods of claying with deeper incorporation were used," he says...
