Fertilizer Management

Are we measuring the right soil nitrogen pool?

Researchers wanted to see if soil protein, extracted using the ACE/MACE methods, is an appropriate measure of the soil nitrogen that potentially becomes available during the growing season. They found only a weak correlation, and concluded that current soil test recommendations provide an acceptable measure of biologically available nitrogen. “Revisiting nitrogen fertilizer recommendations for Saskatchewan:...

Consider seed size when targeting optimum plant stand

Key result: Seeding rates should be established based on 1,000-seed weight, using an on-line seeding rate calculator or on-line apps. Project title, Principal investigator: “Seed size and seeding rate effects on canola yield and quality,” Neil Harker, Agriculture and Agri-Food Canada Lacombe Funding: Alberta Canola, MCGA, SaskCanola, CCC, AAFC, GF2 Recent surveys indicate that approximately...
