Seed Row Tolerance of 16-20-0-13 and 12-40-0-6.5S-1Zn in Western Canada

The majority of phosphorus (P)-based fertilizers are either applied directly in the seed furrow (seed row), or side-banded close to the seed row for the growing of small grain cereals and canola in the Western Prairie provinces of Canada. A research study assessing the effect of low and elevated application rates of 16-20-0-13S compared to other P fertilizers available in the market was conducted. The fertilizer treatments were placed in the seed rows of both spring wheat and canola.

The majority of P-based fertilizers are either applied directly in the seed furrow (seed row) or side-banded close to the seed row, for the growing of small grain cereals and canola, in Western Canada. Farmers using ammonium phosphate-sulfate (16-20-0-13S) fertilizer have reported that they can safely apply greater rates of phosphate in the form of 16-20-0-13S in the seed row compared to regular monoammonium phosphate (11-52-0).
