Rain clouds blocked from moving into Brazil by a hot air system over northern Argentina and Uruguay have been unloading over Argentina's central soybean and corn regions during the last week. And weather forecasts indicate there is more rain to come.
Up to 13 inches of rain has fallen over parts of northern Buenos Aires province in the last week, while southern Santa Fe and Cordoba provinces also received up to 8 inches.
Generally speaking, soybean and corn crops have welcomed the rain after dry spells in December and January.
In areas that received 2 to 4 inches, that is certainly the case, with soybeans and later-planted corn definitely benefitting.
And if rainfall recedes over the weekend, all areas will enjoy net benefits.
But the continuation of the excessive rains could bring development and disease issues in northern Buenos Aires and elsewhere, warned the Rosario Cereals Exchange this week.
At particular risk are later-planted soybeans, it said.
Fortunately, the cold front that brought the rain appears to be displacing farther north and storms will reduce in intensity, according to Meteorologia de Buenos Aires (MetBa), a local weather services.
Soybean planting was completed last week with the end of field work in the far north, the Buenos Aires Cereals Exchange said this week. It estimates total area at 50.2 million acres.
The exchange said soybeans are in good condition across all the principal producing areas and it is maintaining its forecast of 53.0 million metric tons (mmt) for the crop.
The rains also helped in the development of later-planted corn, which is now in good or very good condition, although the rain has come too late for some early-planted crops, it said.
