Should we promote grassland ? A microeconomic analysis

Unfavourable or no incentives at all make the farmers use insufficient grassland areas, from the society's and economic efficiency's point of view. On the one hand the CAP premium encourage to exploit more crops and less grasslands than what real profit would imply. On the other hand, the farmer who seeks to maximise his profit does not take into account the effects extemal to the market due to the lack of incentives. However the market could contribute to the provision of grasslands the society needs, because milk and meat produced by grass-feeding have specific characteristics valued by the consumer. Nevertheless, the public good characteristics of grasslands make market failures remain and public policy become necessary

Effects of sulphur fertilization on Belgian grasslands

During the last two decades, both the atmospheric supply of sulfur and the utilisation of sulfur containing fertilisers has dramatically decreased, whilst yields have increased. Consequently, sulfur could be limiting for plant growth. The effects of factorial combinations of sulfur and nitrogen fertilisation on grasslands at four locations were studied. Sulfur fertilisation increased annual yield at three sites in 2002. These increases were observed mainly at the highest nitrogen fertilisation level. Supplying sulfur also increased protein production (up to an equivalent of 40 kg N ha-1) in 2002. It appears that the environment does not always supply enough sulfur for grass growth anymore and that sulfur deficiency depends on the nitrogen fertilisation level
