Extreme heat conditions in Argentina's core region have led to significant losses in 2nd grade soybeans and a potential 10 to 30% drop in 1st grade soybeans, according to a report from the Rosario Stock Exchange. The region experienced temperatures above 30°C for nearly 90 hours in the past 10 days, causing an approximate loss of 8 millimeters of water in the soil per day. However, a shift in a high pressure system is expected to bring widespread rains to the Pampas region, potentially mitigating further losses.
