Crop progress was favorable over the last month for many farmers, but now many fields in southern Minnesota are wet or have standing water after heavy rains over the weekend

While the September rains might not have the impact on crops that June rains had, Farm Management Analyst Kent Thiesse says standing water can become an issue.

“You can get a lot of stock diseases in corn and soybeans, so the plants will get weaker and then if we get some strong winds, as we usually do in the fall, tend to have more lodging and stock breakage. The other thing that happens when you get late in the growing season like this, crops as they reach maturity use less moisture, so you have less uptake out of the soil of moisture and also daylight starts getting shorter so you get less evaporation.”

So far this month in the backyard at the KTOE Studios, we have received 4.72 inches of rainfall.

Even though planting took place later than normal this spring, Thiesse says the good news is that the area has been running around 10-percent ahead of normal for growing degree units.

“Which has kept the crop kind of coming along, so if we can finish off here with some fairly nice weather in September, average or above average temperatures, the crop should mature in good shape. Certainly with corn that’s always a plus, because if you can dry it down naturally in the field and save on some drying cost and with margins as tight as they are, any dollars you can save on any input costs is a big plus.”

At this point, farmers are mixed on crop yields and it’s expected there will be a wide variation of results for corn and soybeans.

“The soybeans will be interesting because obviously, you got the drown out spots. I think the soybeans got the potential in a lot of places to maybe be a little better than we thought a couple months ago, just because the August weather was pretty favorable. The corn is a problem I think. Especially south and west parts of south-central Minnesota and into south-west Minnesota and northern Iowa. It just never recovered from all the heavy rains back in June.”

According to the latest Minnesota USDA Crop Report, 6-percent of the corn crop has reached the mature stage, that’s one week ahead of average. Seventy-five percent of the crop is rated good to excellent.

As for soybeans, 36-percent of the crop is turning color or beyond, four days ahead of average. Soybean conditions declined slightly to 69-percent good to excellent.
