The good news for producers in Brazil is that forecasts are for the scattered showers to continue during the next 10 days. Some of the areas least affected during the last two weeks may turn out to have more favorable conditions going forward.
Further to the south, Argentina has been faring only slightly better. Periods of showers during the last 30 days have been relatively consistent in the state of Buenos Aires. Despite some cold intrusions that have brought some freezing conditions to developing winter wheat, the increased moisture should have winter wheat in good shape.
However, that has not been the case elsewhere. Recent showers during the last seven to 10 days have been beneficial across the country, but most of Argentina’s primary crop areas are in drought. The recent showers have been enough to promote planting and early germination, but subsoil moisture is likely lacking.
Satellite images dated on Oct. 18, the most recent image available, showed all but Buenos Aires at less than 50% of normal soil moisture. Current forecasts call for some showers over the middle of the country on Wednesday, but that is followed by almost a week of dryness.
Should the dryness continue further, the available topsoil moisture will be depleted quickly with stress to developing summer crops likely.
