Soil testing a must before mouldboard ploughing

摘要

rials being run in Western Australia show growers who planned to lime paddocks intended for mouldboard ploughing or spading should first soil test to 30 or 40cm below the soil surface. Deep soil testing before mouldboard ploughing or spading is critical, new Western Australian research has revealed. The trials, funded by the Grains Research and Development Corporation (GRDC) and Department of Agriculture and Food (WA), have been conducted this year at Badgingarra by DAFWA researcher Craig Scanlan. They are the first formal trials in WA to investigate the effect of soil amelioration - used by growers to address non-wetting soils - on crop nutrition.
