Better planting equipment, improved soybean genetics and technology advancements such as seed treatments and weed control systems have moved soybean planting dates earlier in recent years. Last year 34% of Iowa’s soybean crop was planted by early May; this year only 1% of Iowa’s soybean acres are planted as of May 13.
Although there is a correlation to higher yield potential with earlier planting dates, it’s important to remember that soybeans respond favorably to early-planting datesif soil conditions are ideal for planting. Conditions weren’t fit for planting soybeans in late April or early May.
One silver lining in the delayed soybean planting is that soil temperatures have warmed. We recommend planting soybeans when soil temperatures are about 60 degrees, and soil temperatures were averaging only in the low 60s around May 15.
Planting into a field that is too wet or too cold early in the season will reduce emergence and plant population, which most often leads to reduced yield. Remember, planting soybeans in warm but wet soils can also have a detrimental impact on yield. Patience will continue to be key this planting season!
West Central Iowa started planting seed corn for the second time Friday, May 10. As of Monday night, one of my dealers was excited to share that his wife went for her evening walk and saw corn emerged in his field. This is the first emerged corn I have heard of in the area to date. This same dealer is starting to plant seed beans today. By my estimate West Central Iowa is 45 to 55% done planting corn and 5% done planting soybeans.
North Central Iowa started planting seed corn for the second time Sunday, May 12. Having received more snow than my Western territory, the northern area needed a few more days to dry out before returning to the field. Everything seems to be progressing nicely but no fields have emerged as of yet. North Central Iowa is 35 to 45% done with corn and 2 to 3% done with soybeans.
