Actually urea (AKA diaminomethanone, CH4N2O) is an organic nitrogen-containing compound which is widely used for fertilizer. While it is sold as commercial fertilizer, it still is an organic compound, even if its use may not necessarily be considered kosher for organic farming.
Yes, I agree with you, Wikipedia isn't the greatest source for information, but urea's chemical formula is accurate when I check it against other web-based chemistry sources.
