Following a week of warm and windy weather, Iowa received some much needed rain on Monday June 18. The rainfall amounts weren't a lot - as the range was from one-quarter to three-quarters of an inch. But the rain did generally fall in the driest areas of the state.
Corn condition is basically unchanged from last week at 1% very poor, 3% poor, 18% fair, 57% good and 21% excellent, according to the weekly weather and crop condition survey released June 18 by Iowa Ag Statistics Service. Soybean condition is also virtually unchanged from the previous week at 3% poor, 20% fair, 60% good and 17% excellent, says the government report.
A week of warm, windy weather resulted in one third of the state's topsoil being rated either short or very short on June 17 - which is the day the survey results were gathered and compiled. This topsoil rating is a significant change from a week earlier when over 90% of Iowa' stop soil had adequate or surplus moisture. Only a few areas of Iowa saw any precipitation during the week of June 10 to 17. The dry weather this past week allowed farmers to catch up on spraying crops for weeds, although winds prevented some herbicide applications.
Iowa has nearly "full tank" of subsoil moisture
There were 6.6 days suitable for fieldwork, compared to 5.7 days last year at this time. Topsoil moisture rated 4% very short, 29% short, 64% adequate and 3% surplus across the state. Subsoil moisture rated 1% very short, 8% short, 82% adequate and 9% surplus as of June 17.
Oats headed are at 67%, marginally behind last year's 68%, but ahead of the five-year average of 63%. Oats across the state are beginning to turn color. The condition of the oat crop is zero percent very poor, 3% poor, 20% fair, 61% good, and 16% excellent.
Average corn height is 24 inches; an increase of 10 inches from the previous week. Corn condition is basically unchanged from last week at 1% very poor, 3% poor, 18% fair, 57% good and 21% excellent. Soybeans are 97% emerged. Soybean condition is also virtually unchanged from the previous week at zero percent very poor, 3% poor, 20% fair, 60% good and 17% excellent.
First cutting of alfalfa hay, at 79% complete, remains well behind last year's 96%, but slightly ahead of the 5-year average of 76%. All hay condition is 2% very poor, 10% poor, 30% fair, 49% good and 9% excellent.
Also on June 17, pasture condition rated 1% very poor, 5% poor, 28% fair, 54% good and 12% excellent. Fly populations have become an issue for some farmers. Heat and rising humidity cause stress for livestock, the survey notes.
