Preventing sulphur deficiency boosts canola yields
John Patterson reports on sulphur deficiency in canola and the benefits of balanced N:S ratios. The piece notes variable soil sulphur, deficiency symptoms, and the use of sulphate products, with a practical “insurance” application. It also introduces free software for farmers to compare crop yields and acreage data via the Harvest Production Report, 1992–1996 data, available on disk or online.
