Switching from spring-applied ammonium sulphate fertiliser to autumn-applied N:P:K plus elemental sulphur has helped a Nottinghamshire grower improve yields and cut nitrogen requirements. Dean Broadberry of Roewood Farm, Winkburn, switched to autumn-applied Omex suspension fertiliser six years ago. He believes the move helped boost wheat yields by about 1.2t/ha (0.5t/acre) and oilseed rape yields by nearer 0.7t/ha (0.3t/acre). With wheat at about 130 pound/t across 210ha (520 acres) and oilseed rapeat 330 pound/t over 93ha (230 acres), this has resulted in useful extra profit, he says.
