Argentine soy prices slump behind US futures
* Soy prices in Rosario sank as much as 3.3 percent to between 1,330 and 1,340 pesos per tonne ($300-$302) from 1,375 pesos in the previous session due to sharp losses in the benchmark Chicago futures market.
* Trade volume remained practically nil for the second consecutive day's trade.
* Soybean futures on the Chicago Board of Trade fell after the US Department of Agriculture surprised the market by raising its forecast of the US 2011 soybean yield in a monthly report, traders said.
* In Rosario, soybeans for May 2012 delivery, priced in US dollars, fell to between $325 and $327, down from at $328 on Friday.
* In the port of Quequen, the oilseed shed 43.8 pesos to end at 1,330 pesos per tonne.
