The effects of sulphur (S) fertilization on forage production, sulphur content and N/S ratio of perennial timothy-meadow-grass (Phleum pratens L.- Festuca pratensis Hudson) and cocksfoot-dominant (Dactylis glomerata L.) swards cropped for one to three years were measured under a silage-cutting regime at six sites in Finland. Soil sulphur status ranged from poor/adequate (fine sand) to good (organic soils). Plant growth responses to supplementary sulphur were small, inconsistent and statistically insignificant. The supplementary S-fertilization increased the sulphur content of forage and decreased N/S-ratios at all sites. However, even in low-S fertilized plots the average sulphur content was very seldomly less than 0.2% on a dry matter (DM) basis, which has been assumed to be an adequate concentration in several foreign studies. High N/S ratios (> 14) were rare. The sulphur content of DM depended more significantly on growth stage and grass species than on supplementary sulphur. According to the results of these experiments, NPKS fertilizers contain sufficient amounts of sulphur to ensure both a good quality and a high yield of grass silage. |
