FT.com / MARKETS / Commodities - Grain stockpiles at lowest for 25 years
Financial Times story about 25 yr lows in grain stocks. It's interesting to see a European (British in this case) report on grain markets. A couple of things I took away from the article:

• The Ukraine halted grain exports. I read in the Globe and Mail today that Argentina did the same. I don't know what that means? Are they worried about having enough?
• The general tone from the quoted trader about concerns for next years crop. Long term agricultural bull markets are almost unheard of. Supply adjusts, that means farmers grow more.
