Sulphur is needed to grow wheat in Ontario. It’s that simple, says Real Agriculture resident agronomist Peter Johnson.
Sulphur deficiency was widespread in the province this year after one of the coldest and driest springs in the past 30 years. The cool temperatures tend to limit the amount of sulphur release, says Johnson who notes that farmers can no longer rely on free sulphur that was once supplied by acid rain.
In this episode of Real Agriculture’s Wheat School, Johnson shows how sulphur deficient areas in a field, which can see up to 50% yield reduction, can contribute to field level losses of 10 to 20 bushels per acre.
“In Ontario, we’re almost at the point where every acre that grows wheat needs at least 10 pounds of sulphur in the sulphate form – that’s the form where it’s best picked up in the spring,” says Johnson.
