Turnip Sowing By Drone - Inter-Cropping Stubble Turnips Into Standing Wheat. One of Shropshire’s leading farmers asked us to inter-sow a crop of Stubble Turnips into his fields of wheat, a few weeks ahead of harvest. The idea being that when they harvest the wheat, the next crop is already well established and will give much improved grazing during the winter months. So, we mapped the fields and the big XAG P100 drone was put to work. For this job we were using the 50 litre granule hopper and we mixed the turnip seeds with and an equal mearsure of white nitrogen fertiliser pearls, so we’d be able to easily see the results on the ground amongst the wheat. The drone was flying at 12 meters per second, about 43 kilometres per hour or 27 miles per hour, so it made short work of even the larger fields. Once the seeds had been sown, we put our faith in nature and hoped that the moist, sheltered, warm environment at the foot of the crop would get the turnips off to a flying start….
