A study was conducted to compare the crop yield response between fall and spring surface
broadcast applications of urea to the industry standard of side-banding urea during the spring
planting operation. The results of a four-year study of barley direct seeded (no-till) at Ellerslie,
AB, having treatments of fall and spring applications of surface applied urea, with and without
urease and nitrification inhibitors, compared to side-banded urea at planting in the spring,
showed that the broadcast applications performed well in comparison. There are numerous farm
operations that are switching from side-banding to pre-plant broadcast urea applications to
reduce the time of planting in the spring.
