Missouri river bottom south of Sioux City, IA
Subsoil maps are a good indicator of how much stress your crops can withstand during dry spells in late May through mid-August. I like these maps that Iowa State University Extension puts out in the fall of the year. In the fall of 2021 Monona county had 2.6 inches in the top 5 feet of soil and we did not get timely rains. Crops suffered. The fall 2022 map basically stated our tank was empty in the top 5 foot. Just as dry as the moon’s surface. In 2023 our county corn yield was 165.4 which was about 15 bpa under our 10 year average. No timely rains in 2023. The fall 2023 maps shows 2.65 inches in the top 5 feet. Again we need timely rains in 2024 to even think about getting close to the 10 year corn average. By the way Monona county has the lowest 10 year average corn yield than any other county in the state manly do to too much water in the spring on the river bottoms.
