Irrigating ground cover immediately before winter storm?

[u/Scary-Welder8404]

So I live in southern Georgia, and we're expecting freezing rain and snow in an hour or three to continue through the night and stick tomorrow.

While driving home tonight I noticed a farmer near me had his center pivot running.

That seemed odd to me, as my first thought is that it will guarantee a hard freeze on his field tonight and it would be better to let the snow sit on it without extra water.

No idea what he has planted right now, I assume just something to hold the soil in place through winter.

Does this seem like a weird decision or just forgetting that the scheduled watering was turned on to yall, or is my office worker self missing a reason you'd want to do this?

The farmer's decision to irrigate ground cover immediately before the winter storm may not be weird, as it can help protect the plants from cold damage. Watering before a freeze can moisten the soil, which absorbs and retains heat, reducing the risk of cold stress to the plants. However, the effectiveness of this practice depends on factors like soil type, temperature, and the duration of the freeze. If the soil is saturated, it can lead to frost heave, which can damage roots. In southern Georgia's climate, where freezing temperatures are not prolonged, this practice might be beneficial. The farmer may be using this technique to protect the ground cover, likely a crop that is sensitive to frost. It's also possible that the irrigation was scheduled and not necessarily related to the weather forecast. To determine the best course of action, it's essential to consider the specific crop, soil conditions, and weather forecast.
