Some of our most southern areas have already begun harvesting corn and the rest should be starting this month. Something to keep in mind when harvesting is how you will manage the corn residue.

Decision making in farming can be tough. There are so many management strategies and products that have the potential to increase net revenue. One way to make it easier is to establish a baseline for yield in every field.
Early fall is mostly pre-harvest time in my area. We can evaluate the past growing season and consider possible changes to our operations. One of the most commonly discussed programs this summer has been
the LibertyLink® system for 2017.
Take one last chance to scout before harvest begins. As you walk fields, look at disease levels. Which hybrids handled disease better? Are you happy with your fungicide applications? Look at grain fill and pollination. Take a final assessment of weed control and make note of what weeds are present and if they need to be targeted next year. In soybeans, be on the lookout for Palmer amaranth, as it has been identified in southern Indiana.
As the growing season comes to an end, it’s always a good idea to review weather records and the various practices that you experimented with on your farms. Once again, weather events created challenges throughout the 2016 growing season that were beyond our control.
The 2016 crop continues to mature, though it may not be quite as fast or large as many predicted just a few weeks earlier.
As harvest progresses, it’s important to take time to look at what the corn crop has to tell us. Walk your fields and evaluate hybrids for disease, stalk quality, and nutrient deficiencies. Not only will a last minute scouting session help us evaluate the farming and management practices implemented this past year, but it will also help us plan for harvest work. Now is also the time to explore options for residue management and fertilizer decisions.
The end is near for the 2016 crop! As we prepare equipment for harvest, take time to review your plans for fall. Will you be sowing wheat, collecting soil samples, establishing cover crops, or even improving your fields’ drainage? There’s still time to review these plans to make sure these fall projects go smoothly.
I get excited when farmers innovate and develop simple solutions to production challenges that provide immediate return on investment. John Miller from Catlin, IL has done just that with his Nitrogen Sealing Systems.
As we near harvest, I wanted to review stalk rots. We commonly see a few of them in Iowa that cause a lot of headaches during harvest.
As corn begins to dry down for harvest, we need to be on the lookout for corn ear rots. Numerous fungi exist that can cause ear rots, all of which are influenced by specific weather and environmental conditions. Cool, wet conditions at silking would tend to favor the development of Gibberella ear rot, while Aspergilus will tend to be an issue when conditions are hot and dry.
As we approach harvest, three critical observations come to mind. First, be sure to note any fields that are showing signs of nutrient deficiencies. Often times, fields are only soil sampled every two or four years. In the case of newly acquired farms, the previous fertility levels may not be well known, so if deficiencies are present, taking soil samples after harvest and fertilizing accordingly can prevent the same deficiencies the next year.
Conditions throughout many parts of Wisconsin and northern Illinois have been favorable for the development of corn ear molds. Ear molds are of particular concern because of the adverse effects they can have on grain storage. They also result in the development of mycotoxins, which can have detrimental effects on feed value and animal health.

Harvest time is finally here and for most of us in the South, this will be the year to forget! Parts of Tennessee encountered the worst drought we’ve seen since 2012. On the other end of the spectrum, parts of Kentucky, southern Indiana, and southern Illinois caught more rain than they could handle for most of the year. The Missouri Bootheel couldn’t make up its mind if it wanted to be too dry or too wet! All of these crazy environmental conditions have led to some serious standability issues in our corn. Just about every corn field I’ve been in recently has shown signs of premature death and stalk rot. This is something we see every year, but some years are worse than others and may require a little more planning before harvest.

While August starts the downhill slope of the growing season, a lot is still happening out in the fields. Kernels and pods are filling out and we watch the sky for those ever-important August rains. We may often feel that there is little that we can do to impact the crop at this point in the season. However, there is much we can learn now by walking fields and asking ourselves which fields look the best and the worst.
August is the time we should continue to scout for late-season diseases and pests. Southern rust is the biggest issue we see in corn this time of year and is something you should definitely keep in the back of your mind.
Corn fungicide applications are always a highly debated topic. Many swear by them while others swear at them when they spend the money and see little or no yield benefit. Here are a couple things I like to consider before making an application...
August is a pivotal month for both corn and soybean yield development. The developing plants will need plenty of moisture, moderate temperatures, and adequate nutrient translocation to maximize the number, size, and weight of developing kernels/seeds.
What a year it has been. Many areas have experienced both hot and cold temperatures, as well as wet and dry spells. As we evaluate the crop in August, we have a great opportunity to take a hard look at yield potential and yield loss suffered this year.
Disease levels have been low in both corn and soybeans compared to this time last year. In corn, early observations near tasseling showed very light amounts of gray leaf spot, northern corn leaf blight, and common rust. Septoria brown spot has been observed in soybeans.
