Hot and dry is the current theme SE of Storm Lake. This is excellent drying weather to make hay as many balers can be found dotting the countryside but row crop production with short subsoil moisture reserves will suffer. The last measurable rainfall fell back on Memorial Day Weekend. Some farms further to the south and to the east received little to nothing. Rain will be required to keep crops in their current condition. Directly east and in parts of the northern area SE of Storm Lake received minor frost damage mostly in corn the last week of May. Low laying areas and no-till farms received the brunt of this damage. All the corn that I’ve seen with this injury has recovered well.
We are quickly arriving at the V6 stage in corn. This is noteworthy because ear size will begin being determined (number of kernel rows and potential kernels per row). Good growing conditions now will directly influence the highest number of kernels possible.
Corn unevenness is a common sight. In many instances, crop residue may be to blame. Ideally, we want corn at relatively the same height and stage heading into the pollination period. This helps insure maximum pollination is possible. By and large, most of the unevenness found SE of Storm Lake is not severe and not a major concern.
Herbicide carryover is also appearing in some corn fields creating stunted, yellow corn. Fomesafen seems to be the main one this year. Fomesafen is the active ingredient in many popular post emerge herbicides applied to soybeans. The general rule with herbicides containing this chemistry is that the deadline for its use is July 1st due to its long half-life on the soil that can impact the following year’s corn crop. Soil type, soil pH and lack of rainfall are also significant factors. The lack of rainfall after the herbicide was applied in 2020 is probably the main reason this is being seen.
On the soybean side, many fields have established a good stand. They are in vegetative development currently and will begin flowering after June 20th. Many operators are beginning their 2nd and final planned herbicide application this week and will be finishing up towards the 3rd or 4th week of June.
