Response Of Soybean Grown On A Claypan Soil In Southeastern Kansas To The Residual Of Different Plant Nutrient Sources And Tillage, D. W. Sweeney, Philip Barnes, Gary Pierzynski

Kansas Agricultural Experiment Station Research Reports

Soybean yields measured from 2014 through 2016 were more than 50% greater from the residual from N-based turkey litter applications during 2011 through 2013 than in the control where no nitrogen (N) or phosphorus (P) was applied. However, residual from P-based turkey litter applications or fertilizer-only did not result in soybean yield different from the no N-P control. This residual effect on yield was largely due to increased pods per plant.
