Sulphur slumps in OSR

TISSUE monitoring by Scottish company CSC shows sulphur levels in oilseed rape fell on average from 1% in 1990 to 0.4% last year.

Soil sampling confirms the decline in overall availability of the essential nutrient, says Mark Ballingall, of CSC Perth. "In the Borders it went from an average of 15ppm in 1990 to less than 10ppm in 1996, and at our northern sites from 14ppm in 1993 to only 10ppm last year."

Key CSC advice is to obtain a soil test. "At anything less than 8-10ppm there is a high probability you will get a response to treatment." &#42
