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.
â€œA 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,â€� said Laura Lindsey, Ohio State University Extension soybean and small grains specialist. â€œThe 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.â€�
When evaluating soil test phosphorus (P), 65% of the fields had at least a portion of the field that needed P fertilizer.
