ESN Produces Flexibility and Profits for Seed-Row Nitrogen Application

A three-year study conducted in Melfort, SK by Agriculture and Agri-Food Canada examined performance of ESN and urea in
seed-row nitrogen (N) application.

The study demonstrated ESN’s high degree of safety for seed-placed applications. The high degree of safety makes ESN the perfect N source for one-pass, direct-seed operations eliminating additional application and equipment costs. Yield increases observed with ESN translate to significant increases in canola profitability over that observed with urea.

  • ESN and urea were placed in the seed-row at planting at rates of 80 and 120 lbs N/acre.
  • At 80 lb N/acre, ESN produced 7 bu/acre more yield and $52.40/ acre more profit.
  • At 120 lb N/acre, ESN produced 10 bu/acre yield and $71.00/acre more profit.
