Mostly favorable conditions for developing and filling soybeans in Brazil are expected to continue during the next seven days. Major producing states of Parana and Mato Grosso are experiencing enough rain to support filling beans, but not enough to increase disease pressure or to adversely affect the early harvest. In the south, heavy rain late last week in Rio Grande do Sul were very timely, easing stress to developing soybeans after recent hot and dry weather. With the prospects for some additional moderate to heavy rain during midweek, crop conditions will continue to improve.

The only area experiencing a problem this growing season is in northeast Brazil which produces about 10% of the soybean crop. Hot and dry conditions in December were followed by an improving rainfall pattern in early January. However, the hot and dry pattern has returned, and is expected to continue during the next week.

In Argentina, crop weather is generally favorable in the major corn and soybean areas. Most areas have adequate soil moisture for current crop needs of pollinating and filling corn and soybean vegetative development. Enough rain is expected to occur during the next week to support crops along with no persistent heat.
