Iowa Secretary of Agriculture Mike Naig reported that Iowa corn planting reached 1% for the week ending April 12, 2026, with 2.6 suitable fieldwork days, 3.3 fewer than last year. Topsoil moisture was 19% short or very short and 16% surplus, and southern Iowa drought conditions improved.
Wet conditions and limited fieldwork delay Iowa planting, adding modest upside to corn and soybean prices if the wet pattern continues into May.
