# Excess rain delays soybean planting and affects corn crops in Rio Grande do Sul

> 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.

## Why it matters

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.
