Corn and soybean plants are continuing to suffer in some parts of Iowa from excessive heat and drought. This has been seen especially in far northwest Iowa where drought conditions are worsening.
Large areas of Plymouth and Woodbury counties are in extreme drought, according to the U.S. Drought Monitor. It’s the first time in nearly a year that any part of the state was that dry.
Much of the state’s corn crop is at its peak demand for water, and the soybean crop is approaching its peak. A small percentage of corn had begun to show silk for pollination as of Sunday, and about 13% of soybeans were blooming, the USDA report said.
In the past three weeks, the percentage of the state’s corn that is rated good or excellent has dropped from 86 to 77.
Although there is drought in part of the state, soil moisture is still improved from a year ago. About two-thirds of the state’s topsoil and subsoil has adequate or surplus moisture, whereas last year more than half of the soil was short, according to the USDA report.
