Argentina's agricultural sector is expected to receive much-needed rainfall next week, according to the Buenos Aires Grains Exchange, following a severe drought due to the La Nina weather phenomenon. The rains, expected to total between 0.4-3 inches, could mark the beginning of a return to normal after the drought that has plagued the country for nearly a year. However, cold and dry polar winds are also expected in the country in the coming week. The La Nina climate pattern is predicted to shift to a "neutral" position, potentially bringing back some rains. The most significant impact of the drought has been on the soybean harvest, which is projected to be the lowest in nearly a quarter of a century.
