Yield trends continue to improve with the adoption of better genetics and agronomic practices, leaving soils deficient of nutrients in critical periods. Relatively immobile nutrients may be accumulating near the soil surface due to adoption of zero tillage and shallow banding. Periodic (three years) deep banding (5-6”) of immobile nutrients will be compared to annual shallow banding to provide and economically and agronomically viable solution to achieve potential yields and increased return on investment.
The three study sites (Falher, Vegreville & Lethbridge) will cover different soils (brown, black and grey) and growing season conditions (long, medium and short) to represent most areas of Alberta and other parts of western Canada. The study uses fields under direct seeding for 10 or more years. Research technicians will deep banding fertilizers at 5-6” depth with 3 X rate before seeding in year one with direct seeding implements. The study will take place on canola, wheat and pea crops.
