By Dusty Sonnenberg, CCA, Ohio Field Leader: a project of the Ohio Soybean Council and soybean checkoff
Soybean fertility studies, relative maturity, row width, seeding rates, and the benefits of adding wheat to the rotation were just a few of the topics covered by Laura Lindsey in a presentation given at the Conservation Tillage Conference in Ada last week.
“A study conducted from 2013-2015 with 199 farmers in Ohio looked at cultural practices, and measured soil fertility and
soil cyst nematode levels in 600 fields,?? said Laura Lindsey, Ohio State University Extension soybean and small grains specialist. “The study investigated both the highest yielding areas of the field and lowest yielding areas of each field and compared them. Soil fertility was a primary factor that accounted for yield differences.??
When evaluating soil test phosphorus (P), 65% of the fields had at least a portion of the field that needed P fertilizer.
