Current world fertilizer trends and outlook to 2011/12
This report provides an overview of information on the world fertilizer situation in 2007/08 and a forecast till 2011/12. The fertilizer situation is examined in relation to crop production and factors likely to affect the latter. High commodity prices experienced over recent years led to increased production and correspondingly greater fertilizer consumption as reflected in tight markets and higher fertilizer prices at the start of the outlook period. While demand for basic food crops, for high value crops such as fruit and vegetables, for animal products and for crops capable of being used to produce bio-fuels is likely to remain strong, it is expected that increased fertilizer consumption required to support higher levels of production will be adequately catered for by growing supply world wide during the outlook period.
