Corn Newsletter : 2016-06

    I ran this article last week.  Thank you to all who filled out the survey!  Our goal is to document soybean management practices and yield from 270 soybean fields in Ohio during the 2014 and 2015 growing seasons.  Right now, we are 185 fields short of our goal, but we are continuing to collect data through the month of April. 

    To participate in this research, please see the online survey:

    Ohio State is looking for farmer cooperators and crop consultants to help conduct on-farm field trials this year. Updating fertilizer recommendations is a major undertaking that will require a collective effort from numerous OSU extension personnel, crop consultants and farmer cooperators. We will be looking specifically at N, P, K and S in corn, soybean and wheat. We hope to collect data from a large number of farms across the state and determine economically-optimum fertilization rates to maximize farmer profitability.

  3. Streaming nitrogen on wheat
    Author(s): Ed Lentz, CCA, Laura Lindsey, Steve Culman

    In many southern Ohio locations wheat has already reached Feekes Growth Stage 5. This is an ideal time to apply spring nitrogen: plants will soon begin a rapid uptake of N and the potential for N loss will be reduced because of this larger demand. The northern part of the state has begun to green-up and N can be applied as soon as fields are fit for equipment.

  4. Cover crops
    Author(s): Rory Lewandowski, CCA

    Cover crops provide multiple benefits with regards to protecting soil from erosion, improving soil health, and as a component of a nutrient management plan.  For those cover crops that over winter and resume growth in the spring, for example, cereal rye and annual ryegrass, an important question is when to terminate that cover crop.  That decision should consider the next crop, planting date of that next crop, the spring weather pattern and purpose of the cover crop.   For cover crops that have not been planted with the intention of providing a forage harvest, and that are on acres intended

  5. Winter wheat progress 3-7-16
    Author(s): Laura Lindsey, Ed Lentz, CCA, Pierce Paul, Mark Loux

    On March 16 and 17, we visited our wheat trials in Clark County and Pickaway County. Both locations were at Feekes growth stage 5 (leaf sheath erect). In northwest Ohio, wheat is at green-up to Feekes growth stage 4.

    Generally, Feekes growth stage 6 occurs in southern Ohio during early April; however, with abnormally warm temperatures, Feekes growth stage 6 (jointing) may occur sooner. To evaluate wheat for growth stage 6 follow these steps:

    1- Pull, or better yet, dig up, several clusters of tillers with roots and soil from multiple locations in the field;

  6. Soybean cyst nematodes
    Author(s): Anne Dorrance

    These fluctuating temperatures that we have had this spring where we go from snow days to short days provides some opportunities to get the crews out and enjoy some nice weather.  Sampling for Soybean Cyst Nematode is fine to do in the spring, especially in years where the ground thaws early. 

    It is becoming increasingly important in Ohio to know your numbers.  Sounds like a cholesterol warning doesn’t it?  In the case of SCN, less than 500 eggs per cup of soil and keeping it under 1,000 is what we need to shoot for on some fields.  Non-detectable levels are like gold.

    These warm days have the engines warming for an early planting but the soil temperatures from around the state are highly variable and still on the cool side.  From the weather stations at the branches, these are the soil temperatures at 2.5 inches, from March 21:

    This week’s topic in “The Big Data Confusion” series touches on the importance of data ownership.

  9. Author(s): Jim Noel

    There are no changes to the weather and climate outlook.

    We expect a rain system March 23-24 with rainfall generally under 1 inch. Another system will pass through about March 27-28 with another 1 inch or less as weather systems remain rather progresssive.

    Precipitation will be close to normal with temperatures above normal the rest of March but only slightly above normal.

    The trend to less wet in April with warmer than normal weather still looks on track.
