OECD Factbook 2008 is the fourth edition of a comprehensive and dynamic statistical annual from the OECD. More than 100 indicators cover a wide range of areas: economy, agriculture, education, energy, environment, foreign aid, health and quality of life, industry, information and communications, population/labour force, trade and investment, taxation, public expenditure and R&D. This year, the OECD Factbook features a focus chapter on productivity. Data are provided for all OECD member countries with area totals, and in some cases, for selected non-member economies. For each indicator, there is a two-page spread. A text page includes a short introduction followed by a detailed definition of the indicator, comments on comparability of the data, an assessment of long-term trends related to the indicator, and a list of references for further information on the indicator. The next page contains a table and a graph providing - at a glance - the key message conveyed by the data. A dynamic link (StatLink) is provided for each table directing the user to a web page where the corresponding data are available in Excel® format.Click to Access:

Nutrient use in agriculture
Click to Access:
Inputs of nutrients, such as nitrogen and phosphorus, are important in farming systems as they are critical in raising plant productivity, and a nutrient deficiency can impair soil fertility. A build up of surplus nutrients in excess of crop and forage needs can lead to losses representing a possible cause of economic inefficiency in nutrient use and also a source of potential environmental harm, in terms of water pollution (e.g. eutrophication of water), and air pollution (e.g. ammonia), while the sustainability of phosphorus resources is a concern as world reserves are diminishing.
