  1. What to do about Nitrogen Fertilizer in Corn?

    Jul 8, 2019

    The most recent Agronomic Crops Network C.O.R.N. newsletter contains an article addressing common questions about nitrogen (N) fertilizer applications in corn. The article addresses concerns due to persistent rain this year causing concern about N loss from denitrification and leaching. Common questions being asked are addressed and include:

    Do I need additional N?

    What tools can help me determine if I need additional N?

    How late and how much N should be applied?

    What is the best N source to use?

  2. New fact sheet reporting relationships between soil test extractants published by Culman Lab

    Jun 18, 2019

    The Soil Fertility Lab has published a fact sheet reporting their results investigating the relationships between commonly used soil test extractants in the Tri-State Region. The fact sheet reports findings for soil samples collected in Ohio and Indiana from a diverse range of fields. Soils were tested for Mehlich-3, Bray-P, and ammonium acetate extractable nutrients for phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg). The summary of findings can be found in the full news article and the fact sheet can be found HERE

  3. The Soil Fertility Lab has two new graduates!

    Apr 30, 2019

    We are excited to announce that the Culman Lab has two new graduates! Congratulations to Jordon Wade and Noely Gonzalez-Maldonado on completing their graduate degrees. Jordon's PhD dissertation, entitled "Soil Health and Nutrient Dynamics in Agroecosystems of the Midwestern US", focused on elucidating how soil health measurements influence and are influenced by fertilizer applications. Noely's MS work, entitled "Evaluating the Effects of Long-Term No-Till and Crop Rotations in Soil Health and Corn Productivity, focused on determining the effects of half a century of continuous no-till and crop rotation on soil health and its relationship with crop productivity. Both theses will be made available on our website soon!

  5. Now hiring!

    Feb 12, 2019

    The Soil fertility Lab is looking for a summer intern interested in agroecology field crop research and soil health to assist with a project investigating the long-term effects of different tillage and crop rotation practices on soil properties and corn, soybean, and hay productivity. The student will synthesize data to answer questions related to a topic of interest chosen by them. In addition, they will be provided field and lab opportunities working with a team of postdocs, grad students, and technicians. A stipend is provided for this position. 

    Full details, including how to apply, can be found here 

  6. Soil Fertility and Nutrient Management in Hops

    Feb 4, 2019

    The Soil Fertilty Lab is looking for hop growers to participate in our new research project. Details on the project, as well as cooperator involvement, can be found here. This is a two-year study that we hope to expand upon with further research after completion. Inputs from growers, as well as our advisory committee consisting of select regional growers, will form future research questions. We look forward to establishing a strong connection with the hop growers of the North Central region and working with you to answer questions and establish best practices in hop soil fertility and nutrient management. 

  7. Congratulations, Phoo Pye Zone!

    Jan 31, 2019

    In December 2018, Phoo Pye Zone successfully defended her Masters of Science from the School of Environment and Natural Resources. Her research focused on evaluating the response of soil test values and fertilizer on corn, soybean, and wheat tissue levels. Phoo plans on publishing this work in both peer-review and factsheets. Congratulations, Phoo!

  8. Soil Balancing Call-in Conversations

    Oct 2, 2018

    Soil management not only impacts crop yields, but also has a huge impact on the environment. For organic farmers, soil balancing has become a widely used method for soil management. Soil balancing is done by managing base cation saturation ratios, which can be an overwhelming concept to understand. As such,  our multidisciplinary team at Ohio State University is offering several opportunities for people to participate in phone-in events designed to provide conversations about the basis and practice of soil balancing. Researchers will be on hand to provide input and answer questions but the main focus will be to hear from callers and learn from their experiences. The phone-in conversations are a three-part series beginning this month. Click on the heading to view more information. 

  9. Evaluation of Adapt-N and FieldView Corn N Fertilizer Tools in Ohio

    Sep 26, 2018

    In a recent article for the C.O.R.N. Newsletter, Steve Culman reviews the evaluation reports from NutrientStar for Adapt-N and FieldView, tools to provide farmers with customized corn nitrogen (N) fertilization rates. The article provides a summary of their findings and also provides additional information on an alternative approach to determine corn N fertilization rates. To view the full article, click here

  10. Considerations for planting winter wheat

    Sep 6, 2018

    For farmers considering the addition of wheat to their crop rotation, it's time to figure out management strategies as soybean harvest is fast approaching. Laura Lindsey, Pierce Paul, Ed Lentz, and the CCA have written an excellent article for the C.O.R.N. newsletter on wheat management. The article provides a link to the Ohio Agronomy Guide on winter wheat management and goes over some key management decisions impacting how successful your wheat crop will be.
