Third largest ag exporter is... the Netherlands?

Take the case of the Netherlands. Unbeknown to most people, it is world’s third largest agricultural exporter, despite having little land (it has the world’s fifth highest population density). This has been possible because the Dutch have “industrialised” agriculture by, for example, deploying hydroponic agriculture (growing plants in water) that uses computer-controlled feeding of high-quality chemicals—something that would not have been possible if the Netherlands did not have some of the world’s most advanced chemical and electronics industries.

Via Chang via Yglesias via MR. Note that the data is from 2003-2004 (I was suspicious because Brazil didn't breach the top ten). But nevertheless an impressive feat. Although it's worth mentioning that a large $ trade surplus in agriculture is not the same thing as being self-sufficient - the Netherlands is as exposed to rising staple crop prices as any other country (albeit with a high level of income, so consumers don't feel the hurt nearly as much).
