Growing Returns, a Blog of the Environmental Defense Fund, discusses efforts led by Soil Fertility Specialist and School of Environment and Natural Resources Assistant Professor Steve Culman, in the post, “New guidance to maximize every drop of fertilizer in Ohio and beyond,” to update the Tri-State Fertility Guide for Corn, Soybean, Wheat and Alfalfa. To update the Tri-State Guide, Culman is using data from on-farm research trials he and his team have been conducting. This data will be used to inform the new Tri-State recommendations.
Agricultural soil phosphorus levels held steady or trended downward in at least 80 percent of Ohio counties from 1993 through 2015, according to recent findings from the College of Food, Agricultural, and Environmental Sciences at The Ohio State University. The findings, part of the college’s Field to Faucet initiative, represent good news for Ohioans concerned about protecting surface water quality while maintaining agricultural production, according to college researchers Elizabeth Dayton, Steve Culman and Anthony Fulford.
A study of how natural gas pipeline installations affect Ohio cropland productivity begins this fall thanks to a $200,000 gift from Kinder Morgan, Inc. to The Ohio State University. The study, to be overseen by the College of Food, Agricultural, and Environmental Sciences, focuses on soil disturbance caused by statewide pipeline installations. Kinder Morgan’s gift allows the college to begin identifying and sampling soil from farmer fields this fall, said Steve Culman, soil fertility specialist with Ohio State University Extension and project leader. OSU Extension is the outreach arm of the college.
The Ohio State Soil Fertility team put on a soil health workshop to educate OSU Extension educators, graduate students and staff on the latest science of soil health. Two identical workshops were held on April 21 and 27th at OARDC in Wooster. The full day workshop exposed participants to concepts of soil health, promising tests available and what these tests functionally reflect in the soil. The morning session was mostly informal lectures and discussion followed by hands-on experience in the laboratory running the tests. Speakers included John Obrycki, Vinayak Shedekar, Rafiq Islam, Anthony Fulford, Tunsisa Hurisso, Vijay Chaganti and Steve Culman. A total of 55 participants attended the workshops which will be offered again, sometime in late summer, date TBD.
It’s been 20 years since agronomists have developed fertilizer recommendations in Ohio. But now, Ohio State University Extension is embarking on a major initiative to determine the optimal rates of fertilization on the state’s major crops. The goal is to not only maximize farm profitability, but also contribute to improved nutrient management and water quality in the state. The Ohio State University On-farm Fertilizer Trials project plans to gather data from hundreds of farms statewide over the next two to three years, said Steve Culman, soil fertility specialist with the university’s College of Food, Agricultural, and Environmental Sciences and researcher with the college’s Ohio Agricultural Research and Development Center. OSU Extension is the outreach arm of the college.
Soil Fertility Specialist Steve Culman is looking to recruit growers interested in helping researchers update the soybean, corn and wheat fertility recommendations for Ohio, Michigan and Indiana. He is seeking growers to participate in a project to look at nitrogen, phosphorus and potassium in soybeans, corn and wheat as part of an overall effort to update the tri-state fertility recommendations.
This week's Conservation Tillage Conference in Ada, Ohio, is expected to draw more than 900 participants. The program will feature a day-long discussion with industry and university experts on improving Ohio’s water quality, particularly ways to keep phosphorus and nitrogen from impacting water resources. Nutrient management, cover crops and soil health and Solving the P (and N) problem are just a few of the sessions offered at the conference. SENR faculty experts, including Robyn Wilson, Steve Culman and Warren Dick, are scheduled to present their research.
The 36th Annual Ohio Ecological Food and Farming (OEFFA ) Conference, "Sustainable Agriculture: Renewing Ohio's Heart and Soil" will be held this weekend (February 13-15) in Granville, Ohio. The conference offers numerous workshops and a full-day pre-conference event featuring Ohio State and industry scientists, specialists and students. Steve Culman, assistant professor in the School of Environment and Natural Resources, who also serves as the State Soil Fertility Specialist for OSU Extension, is one of the presenters in the featured workshop, "Love Your Healthy Soil" and will explain the available tests for active soil organic matter.
Corn and soybean growers in Clark County and other surrounding counties with similar soils and growing conditions are welcome to learn from state specialists about a range of topics designed to help them understand what their crops have gone through this spring. The Western Agronomy Field Day is July 16 at the Western Agricultural Research Station, located in South Charleston. Steve Culman, an OSU Extension specialist in soil fertility and SENR faculty member will discuss fertilization.
