Experimental Factors
Timing (2): Fall compared Spring applications
Urea Granule Size (2): regular 3mm and large 10 mm size urea granules
Inhibitor Additions (3): regular untreated urea, urea treated with Agrotain, and urea treated with Agrotain plus a nitrification inhibitor (DCD)
Incorporation (3): no incorporation, harrowing incorporation, and sweep chisel-plow tillage incorporation
Experimental Design
The study will be a four replicate, factorial design, with the inclusion of a no-N control treatment, and a standard farmer practice of side-banding at planting treatment for comparison purposes. The last two treatments will not part of the factorial design and statistical analysis, but are included to assess N response and how the technologies being evaluated compare to standard farm N applications for central Alberta.
