- Abstract
- Atmospheric sulphur (S) depositions have been decreasing in Europe for the past 20 years. Up to now, there were no evidences of S deficiencies Oil Cut grasslands in Belgium. The effects of S fertilisations together with incremental nitrogen (N) dressings were investigated in Belgium using small plot trials on cut grassland between 2001 and 2003. In 4 cases out of 13, S supply increased dry matter yields on average by 0.8 t ha(-1) y(-1). Response to S appeared to depend on the site, the year, the N fertilisation level and the soil. Grass S content was significantly increased and N:S ratio decreased by S fertilisation. High N:S ratio (> 14) was observed in grasslands without S fertilisation even with a moderate N supply. It is concluded that S deficiency can be feared for cut grassland in Belgium mainly on light textured soils after a wet winter. (c) 2007 Elsevier B.V. All rights reserved.
