If nutrient reserves were not utilized because of environmental extremes, where are these reserves? How big are they? Soil tests will help determine this carryover. Because some may be concentrated at lower depths, growers may consider submitting 0-6” and 6-24” samples. If crops (including non-canola crops that will precede canola in 2013) had heavy biomass but low yield, nutrient in…

Safe rates of seed placed fertilizer depend on seedbed moisture conditions, soil type, row-width utilization, and nitrogen source. For example, the safe rate of seed-placed nitrogen is only 10 pounds of actual nitrogen per acre when using a 1” knife on 9” spacing and seeding into moist, medium soils…

A number of new fertilizer products are on the market, including seed coatings that contain small starter amounts of macro- and micronutrients. On canola seeded at the equivalent of 5 lb./ac., the rates per acre of any seed-coated nutrient will be very low. Growers considering these products are encouraged to leave test strips (link to……
