By Alex Lindsey and Greg LaBarge, Adapted from C.O.R.N. 13-2021 When we examine crop emergence post-planting, two factors can impact speed of emergence — soil moisture content and soil temperatures. If soil temperatures are lower, it can take more calendar days for emergence to occur meaning rowing corn may take a little more time. In the Ohio Agronomy Guide, emergence should begin to occur after approximately 100 air GDDs. A difference in 10 degrees in temperature can dramatically affect how quickly crops will emerge. For example, at a temperature of 60 degrees F heat unit accumulation per...

By Harold Watters and Greg LaBarge, Ohio State University Extension With planting under way, a couple of reminders. Keep fertilizer application records to confirm you are following your nutrient management plan and to keep tabs on changes that may occur in your soil nutrient levels. This is a reminder of several good sources of weather information that can be used as part of your fertilizer application records. http://weather.gov is the standard, and we have told you about this one in our fertilizer applicator certification meetings. From the Ohio Department of Agriculture is the Ohio Applic...

By Harold Watters and Greg LaBarge, Ohio State University Extension When maximizing yield is the goal, controlling early season weeds is critical. Managing weed competition is the one pest management decision we make each year in every field. Weeds compete with the crop for available water, nutrients, and light starting at crop emergence. The first bolded statement in the  Ohio, Indiana and Illinois Weed Guide is “Years of research have shown that good weed control within the first 4 to 6 weeks after crops are planted is critical in order to avoid a yield reduction from weeds.” Sound ad...

After 25 years, the Tri-State Fertilizer Recommendations for Corn, Soybeans, Wheat, and Alfalfa has been comprehensively updated and is now available. The full version can be downloaded as a free pdf, or a printed copy can be purchased at: https://extensionpubs.osu.edu/search.php?search_query=974§ion=product The recommendations are based on more than a decade of field trials evaluating N, P, K, S and micronutrients, including over 300 on-farm trials across 41 Ohio counties. This work confirms that the original Tri-State recommendations provided sound guidelines for nutrient management....
