Southeast Iowa Crop Conditions

Temperatures during the beginning of April were above average reaching the 80 degree mark but since then have been cold. These cold temperatures have deterred some from getting a start on planting. Soil temperatures can vary tremendously during a given day with a temperature swings of 15 degrees not being unusual. Over the last two weeks, average soil temperatures have been in the upper 40s to lower 50s at the 4 inch mark. Corn’s minimum germinating soil temperature is 50 degrees. By all reports, most corn that has been in the ground for a week is just beginning to germinate.

Dry soil conditions are also a concern. There is subsoil moisture to get the crop off to a good start but will need timely rains to keep it going. Planting conditions have been excellent this spring. Areas SE of Storm Lake, especially in the Des Moines Lobe land form region have a history of being over saturated in the spring creating less than ideal planting conditions. That should not be the case this year. Short-term forecast looks favorable with daily high temperatures trending upward with decent chances of precipitation next week. Many acres will be planted in the upcoming days.

In agriculture, there are many traditions and saying when spring comes around. One saying in particular that comes to mind this spring that I’ve heard all my life is “Plant in dust, your bins will bust.” I’ve come to learn that is not always true but I am optimistic about what this growing season has in store.
