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.
Canola yield and profits with ESN and urea seed-row applications at Melfort, SK. Yields are three-year average.
