Heat wave threatens southern US corn crops

Heat wave threatens southern US corn crops

By Jamie Martin

The current heat wave sweeping across the central and eastern United States is setting the stage for potential agricultural distress, particularly affecting the corn harvest in the southern regions.

Temperatures exceeding 90 degrees Fahrenheit and a heat index surpassing 100 F in some areas are causing significant concern among agricultural experts and farmers alike.

The southern parts of the Corn Belt are at a critical juncture, with corn crops beginning their silking phase—the initial stage of reproductive development.

According to Brad Rippey, a U.S. Department of Agriculture meteorologist, this period is crucial as the plants are highly susceptible to heat, which can adversely affect pollination and subsequently reduce the size and number of kernels.

Although the main corn-producing areas in the Midwest are not yet in the reproductive stage, the ongoing heat wave could have long-term effects if it persists.

The expected hotter-than-average summer, influenced by climatic shifts from El Niño to La Niña, could exacerbate these conditions.

Farmers in these regions are urged to engage in rigorous monitoring and to employ mitigation strategies such as adjusting irrigation practices and exploring heat-resistant corn varieties. Such measures are essential to navigate through the challenges posed by increasingly frequent and intense heat waves, which are likely a consequence of broader climate changes.
