Urea 46+0+0, MAP 11+52+0, AS 21+0+0+24S, EL 0+0+0+90S, S15 13+33+0+15S
All fertilizer was broadcast and pre-plant incorporated then packed and seeded with a double disk drill
Soil Test N and S are for 0-24 inches, the P, K, OM and pH are for 0-6 inch soil zone
S-15 $300/ton, MAP $180/ton, AS $180/ton, Elemental $300/ton, Urea $250/ton
Gross Return uses a $0.10/lb canola price
Canola S and P experiments were conducted at Langdon in 2001 thru 2003. A spring soil test was done before fertilization and planting. All fertilizers for the data shown were weighed, mixed and applied with a research cone seeder. The plots were then roto-tilled three inches deep and packed before planting. Seeding was with a double disk drill in six inch row spacing. InVigor 2663LL was planted in 2001, Hyola 357RR in 2002 and Hyola 357 Magnum RR in 2003. Stands were 8 to 12 plants/ft2 in all experiments. Weed control was excellent and the disease infection low in all experiments.
No statistically significant difference was found for yields of canola with S15 fertilizer compared to an equal blend of MAP, AS and ES. The average of four experiments showed a 66 lb/a yield advantage for S15 compared to the blend. At current canola and fertilizer prices the 66 lb/a yield increase would calculate to $1.50/ acre increase in profit due to using the S15 fertilizer.
