Soybean grain contracts are seeing a decrease in prices on the Chicago Mercantile Exchange (CBOT), with March contracts operating at US$ 12.13 per bushel, a drop of 0.75%. This is due to an abundant supply from the start of the Brazilian harvest and a positive production outlook in Argentina. Additionally, concerns about demand in China and the strong acceleration of the dollar against other currencies are also contributing to the downward pressure on prices.
