The drought and heat stress are primarily affecting western and north-central Iowa, where sandy soils are showing signs of crop stress. Farmers in these areas may face reduced yields if rainfall does not improve before harvest. Disease pressures, such as southern rust and tar spot, are minimal this year, reducing the need for fungicide applications. However, input costs remain high, adding financial strain to producers. While eastern Iowa is experiencing favorable conditions, the variability in rainfall across the state could lead to uneven yields.
