Since 1962, Ohio researchers have been studying how tillage affects soybean yields in different soil types through the Triplett-van Doren No-Tillage and Crop Rotation Experiment. A new factsheet, ‘Soybean yield response to over 60 years of no-tillage across different Ohio soils’, shares results from this long-term study, highlighting the findings by de Camargo Santos et al. (2025).

The factsheet highlighted that no-till and chisel plowing were higher-yielding systems than moldboard plowing for soybean production (Table 1). Yield improvements were greater in silt-loam soils (Wooster) than in heavy-clay soils (Hoytville), showing how soil type can play a key role in determining soybean re
