Southern Brazil continues to endure toughest soybean growing
conditions.
Dryness is expected to persist through
Christmas.
The weather forecast for
South America is starting to sound like a broken record. Much of the
same is expected across Brazil and Argentina as seen the past
several weeks: drier across southern Brazil and growing regions of
Argentina, but wetter across Central and Southeast Brazil.
The weather pattern continues much the
same as the past few weeks across South America heading through
mid-December 2021. Beneficial rainfall for crops will fall in Central
and Southeast Brazil, while southern Brazil and growing regions of
Argentina see spotty, if any, rain showers.
Major soybean producing states, like Mato
Grosso, are going into mid-December with plentiful soil moisture. In
fact, the week-ending December 18 is forecast to be the second wettest
mid-week of December in 30-plus years according to data from
WeatheTrends360. The favorable weather bodes well for soybean
yield potential in Mato Grosso, where harvest activities are expected
to begin around Christmas.
However, when we look farther south into
Río Grande do Sul, weather conditions have not been as favorable.
Warmer and drier weather have resulted in poor soil moisture. The poor
weather conditions continue in the middle week of December, which is
forecast to be the eighth warmest and seventh driest in more than 30
years, according to
WeatherTrends360. Drier conditions will extend down into the
growing regions of Argentina; this is forecast to be the eighth driest
mid-December in the same period for the province of Santa Fe.
The forecast is beginning to sound a bit
like a broken record, and for the week-ending Christmas Day (December
25), more dryness is expected across southern Brazil and northern
Argentina. There is a chance that the area of dryness will be a bit
more widespread than the previous week. Hotter-than-normal weather in
southern Brazil and northern Argentina will exacerbate poor soil
conditions there leading to higher evapotranspiration and drier soils.
