Triple sulphur levels could lift OSR yields

摘要

Winter oilseed rape grown on light or shallow soils, in particular, could profit from more sulphur than indicated by the RB209 fertiliser manual, according to new research. Mainly undertaken in Hampshire, Wiltshire and Dorset, the trials show yield and margin responses from applications of up to 225kg/ha of SOs (90kg/ha S). Agrii believes it underlines both the extent to which lack of sulphur is becoming an issue in modern rape nutrition and the value of extra applications in boosting the efficiencyof applied nitrogen.
