May 22: Rain loosens soil for easier emergence

    The past week brought measurable rain over several days, giving the soil the opportunity to soak it in and loosen the crust for easier emergence. The cool weather that followed has put a pause on crop development, but the forecast is turning much warmer. With the excellent moisture we have i…

      May 18: Forecast looks perfect for even and fast emergence

        Not much to report here. Planting wrapped up for the most part last week, and the forecast looks perfect for an even and fast emergence.

        May 11: Week of excellent progress

          After a slow start to planting, most concerns have been eliminated by a week of excellent progress, and most guys in this area will likely be wrapping up this week. After an April of unrelenting rain, some are already voicing concern that the spigot may have prematurely shut off on us. We wo…

          May 4: Weather finally turning the corner

            The weather pattern in east-central Iowa finally seems to be turning the corner. Fields are starting to dry out, and equipment is beginning to move, though overall planting progress remains minimal at this point. We continue to watch the forecast closely as the window to make up lost ground …

            April 27: Meaningful field work limited

              Between the volume of rain and its frequency, meaningful field work across east-central Iowa has largely been limited to tile repair. A brief window opened up the first half of last week for some spraying to take place and a handful of planters to roll on lighter ground, but heavy rain retur…

              April 20: It was a good week for book work

                It was a good week for book work. It was so dry we’re not going to get anywhere anyway that gets us in the field. We also had hail and tornadoes going around us. Manchester, northeast of here, got bombed with rain. Farmers are itching to get out, but we’ve had lots of big storms the past few weeks.

                    Wrap-up: A year of peaks and valleys

                      We finished fall tillage and fall fertilizer applications. We have wrapped up field work. We’re waiting on warm days later this week to wash up equipment and put it away for winter. Overall, it was a year of peaks and valleys. Happy with the early growth and good start, but disappointed in h…

                      Nov. 3: Started fall tillage and got fertilizer on

                        I started fall tillage and got fertilizer on about half of it. We’re making repairs among after-harvest duties. Beans and corn wrapped up for about a week with a little shower early last week. Still got tillage to do. We have had good yields. The farm average corn yield hit 250 bu./acre. Mea…

                        Oct. 27: Preparing for tillage and fall fertilizer

                          I finished corn and baled some stalks to wrap up harvest 2025. Now we’re preparing for post-harvest tillage and fall fertilizer. Our work with cattle went good, and they’re set to be gone and we’ll start with some new ones.

                          Oct. 20: We’ll wrap up harvest with corn this week

                            We’ll wrap up harvest with corn this week with about 100 acres left to get. It’s good to have so much done A little rain didn’t slow down corn. Yields look good for us with 220 bu./acre on the low side and up to 280 on areas sprayed with fungicide. I might start some fall tillage this week. …

                            Oct. 13: Wrapped up harvesting beans and moved on to corn

                              We wrapped up harvesting beans and moved on to corn yesterday (Oct. 12). It’s really dried down a lot — from 24% to 15% in a couple of weeks. We’ll keep plugging away at harvesting corn — maybe 70% left to do. We’re seeing yields of 250 plus for those that got fungicide on it. We may work th…

                              Oct. 6: I hear more rain is coming today

                                It’s sprinkling and I hear more rain is coming today. We are about 70-80% done harvesting beans. Yields are pretty good, ranging 60-80 bu./acre, but most of it closer to 70-80 bu./acre for field averages. By mid-week, we’ll finish beans and switch back over to harvesting corn.

                                Sept. 29: 40-bushel difference where fungicide was used

                                  We had a warm week and we’re getting another one. We got in the field for corn harvesting at Kirkwood Community College and at home. All equipment is working as it is supposed to do. We’ll start on beans this week — hoping to see decent bean yields. Corn yields show a yield difference of abo…

                                  Sept. 22: Most of the rain missed us

                                    We got a little bit, but most of the rain missed us. More combines will roll out this week. Some farmers might switch to combining beans, but so far I’ve only seen corn combining. We’ve been sweeping out bins and a few other last-minute chores to get ready to harvest.

                                    Sept. 15: Just a few combines going

                                      It’s been hot. I checked Thursday with hand shelling. One field is down to 25% moisture. We maybe start combining this or next week. On Wednesday and Thursday we’ll see what the weather does, as there may be rain coming. Beans are turning color this past week. Our last cutting of hay is done…

                                      Sept. 8: Corn looks pretty good all things considered

                                        Corn’s starting to dry down pretty fast in some spots. I drove from here to Ames to the football game this weekend and there are definitely fields that are pretty dry, and that could be from a shortage of nitrogen or southern rust. Corn looks pretty good all things considered on our farm. I …

                                        Aug. 29: Disease progressed fast in fields

                                          We’re getting to the last of the bins. We cleaned the last few loads and took them to ADM and Cargill. We’re getting harvest equipment ready to go. Disease progressed fast in fields. We are maybe starting an earlier harvest than planned. We fixed augers this week. Additionally, I hosted abou…

                                          Aug. 25: Fields are dried out

                                            Weather was good and cooled down nicely at the end of the week. Fields are dried out. All that’s taken pressure off crops from heat. I need to get back in the field. Diseases are progressing pretty harsh through some area fields. It’s not a disaster, just more pressure. That effect could be …

                                            Aug. 18: For so much rain, it’s not too bad

                                              We made a trip to the State Fair and worked on equipment to get ready for fall. We’re wet but not swamped, as we got about half to 1 inch of rain every two to three days in the last week. It’s humid. Crops are showing some stress from diseases and we’ve sprayed fungicide but when it rains co…

                                              Aug. 11: Hot nights pushing tar spot

                                                Corn and beans look real good from viewing around our area. I’d encourage others not to pencil 188 bu./acre for corn as some are predicting because of lingering factors. Fields in our area have some tar spot, and hot nights are pushing it. Farmers might not get heavy test weights, but it wil…

                                                Aug. 4: Check for pollination issues

                                                  I sprayed fungicide last week on corn. The weather has been good, and corn looks really good. I’d suggest area farmers walk their fields and pull corn ears to check for pollination issues. We’ll visit the state fair next week. We’re doing some late summer cleaning and organizing throughout t…

                                                  July 28: Diseases are becoming more noticeable

                                                    It’s been warm, and we keep getting showers and humidity. Diseases are becoming more noticeable. Plan fungicide spraying for today or tomorrow. Beans and corn look good. I’m getting started to be ready for fall as it will be a slow week around the farm. I’ll get software updated and replace …
