Excess rain, high soil moisture and low temperatures are slowing planting in Rio Grande do Sul, according to Emater/RS-Ascar. Soybean planting has reached 10% of the planned area and corn 80% of its 896.4 thousand hectares.
Waterlogged fields are limiting machinery access, and early crop development is slow.
Delayed soybean planting in Brazil's southern state raises the risk of a later harvest and weaker early-season yields. That supports soybean meal and oil prices somewhat, though the effect is limited because the state is a modest share of national output.
After 1,079 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
