Large Seed and Central Fill Planter Setting Recommendations

Author: Denny Cobb

Low commodity prices have drastically reduced margins this year and the best way to make a profit will be to utilize all of your tools to their fullest potential. That means making sure your planter is ready for the field before its time to plant.

Restoring Soil Health After Harvest

Author: Denny Cobb

As harvest progresses, you will see yield variabilities that are unparalleled. For many farmers, this will be a first time experience! You will see hybrids and varieties respond with wide yield swings. Just about any stress you can think of has shown up in our region this growing season. Rainfall intensity and frequent occurrences, planting delays, nitrogen losses, and compaction are the big four. Any one, or a combination of these, will hinder product performance this year.

Helping Cure Compaction and Stagnant Soils with Cover Crops

Author: Denny Cobb

This early fall period gives farmers the opportunity to implement management practices that will benefit them during the 2016 crop season and beyond. Our agronomic area experienced extraordinary rainfall events this past season. The intensive rain events of 2015 have created surface compaction as well as stagnant soils with limited amounts of oxygen and micro life. Cover crops are an excellent means to help cure these issues.

Monitor And Protect Crop Potential

Author: Denny Cobb

Early corn grain fill will be occurring during this period. Virtually all controllable production practices will have been completed with the exception of monitoring non-GMO corn for second generation European corn borer (ECB) infestations, and treating appropriately. This generation generally occurs mid-July to late-August in our area. Trapping adults proves to be the most accurate method of deciding to treat or not. Second generation ECB can be yield devastating. One borer per plant can reduce yield by 7 Bu./A. or more.

UAV's, NCLB and Japanese Beetles in Indiana

Author: Denny Cobb

As Indiana corn continues to grow, scouting efforts have become more difficult. With some fields averaging over 8 feet tall, patterns are impossible to see from inside the field, which in turn makes diagnosing a field much more difficult. UAV's have proven to be a useful scouting tool in our research this summer, allowing agronomists to see the field from a broad perspective without getting into an airplane or helicopter.

Continue Scouting to Keep Disease and Pests in Check

Author: Denny Cobb

Soybean cyst nematode sampling is best done six to eight weeks after planting. Target fields where yields have plateaued, areas with pH>7, and areas where weed control is lacking.

Four Factors for Effective Post Emergence Herbicide

Author: Denny Cobb

This is when many of you will likely be making in-crop, post emergence herbicide applications to both corn and soybeans. All post applications should reinforce your earlier herbicide applications. Careful attention and decision making should include: crop growth stage, weed height, environmental conditions, and tank mix additives. If you carefully manage these four key factors, you will not only achieve greater crop safety, but also enhanced herbicide effectiveness.

Corn and Soybean Plantability Tips

Author: Denny Cobb

Smaller sized seed corn will be the norm for 2015. As you know, this is a result of an excellent growing season which had very few stressors during the pollination and grain fill periods. Overall, smaller size seed corn poses fewer planting challenges than heavier, larger sized seed. Here are a few pointers for planting small size corn seed.

Spring Ammonia Applications and Corn Planting Concerns

Author: Denny Cobb

Last fall was not very conducive for applying ammonia (NH3), which brings us to our current situation concerning spring applications. Couple that with wet soils, cooler daytime temperatures this week, and the need to begin corn planting, there are areas of concern! Here are my recommendations regarding spring applications of NH3.

N. Indiana and Michigan: Managing Pollen Drift in Non-GMO Corn

Author: Denny Cobb

Premiums for Identity Preserved (IP), non-GMO corn are significant. However, these premiums can easily be reduced or lost when purity standards are not met. GMO pollen drift/contamination is the major contributor to non-GMO premium loss. Let’s review some “pollen” facts...

Rainfall continues to be the major limiting or non- limiting factor in my agronomic area.

Author: Denny Cobb
Rainfall continues to be the major limiting or non-limiting factor in my agronomic area. Around 75 percent of my area has experienced scattered precipitation and generally less than desirable amounts of rain. The remaining 25 percent has received good, timely rainfall.

N. Indiana and Michigan: Corn and Soybean Stand Establishment and Scouting Corn Insects

Author: Denny Cobb

Corn Stand Establishment
This past week drenched our region with 4 to 6 inches of rain, followed by cool if not cold temperatures. Corn that has germinated and/or emerged (young plants) should be okay.

Soybean Stand Establishment

Some of the same corn comments hold true for soybeans. About 30% of our area got their soybeans planted last week. Very few fields have emerged.

Stand Evaluations
By all means, when conditions and fields become fit and suitable for planting, plant the “unplanted” acres first! This will give any “challenged", earlier planted fields time to hopefully recover so a proper assessment can be made.

Corn Insects
--- Black Cutworm, Slugs, and Armyworm
--- Purple Corn
