Summer arrives on June 21, but the below-normal rainfall and mostly above-normal temperatures have been with us since the finish of planting. The week of June 12 was slightly above long-term averages in degree day accumulations, marking the third consecutive warm week. Row crops are in generally good condition across Iowa, but questions about the growing deficit in topsoil moisture are common. We have lost little yield potential so far, even though corn has rolled in the afternoon in scattered areas. Ample subsoil moisture is working like a moisture bank now that crop roots are rapidly growing. As we near tasseling, moisture needs will become critical.
