Trials test sowing options to lift income
Plain text source:
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...
