# Heat threatens soybean yields even in irrigated areas in southeastern Mato Grosso

> Early planting in Primavera do Leste and Campo Verde gave some soybean growers an advantage, but high temperatures are now hurting plant development, including on irrigated land. One producer reports dry spells of 10 to 12 days, shorter internodes and water stress, and estimates yield could be compromised if November matches October's conditions. Input costs have risen 20% to 30%.

## Why it matters

Heat stress during the reproductive stage could cut Brazilian soybean output, tightening export supply and supporting soybean and meal prices. Higher production costs may also reduce farmer margins and planting decisions for the next season.
