The objective of this study is to evaluate the effectiveness of various commercially available and potentially available sources of S fertilizer for canola production in North Dakota. Research trials were carried out at two locations near Langdon. The S products included ammonium sulfate (AS), elemental sulfur (ES), compound granules of N, P, and S, gypsum from coal power plant scrubbers, and a plant growth promoting rhizobacteria (PGPR). All treatments were compared against a monoammonium phosphate (MAP) check supplying N and P. Urea-N was added to certain treatments to balance N rates for all seed-row treatments.
