2021 Iowa Soybean SINGULATION STUDY 15 IN. ROWS
The purpose of this study is to compare different methods of singulation in 15 in. rows and their effect on yield and profitability.
BundleDROP cell plates drop soybean seeds in clusters, which is supposed to accelerate emergence in crusted soil conditions. Beck's Colfax, IA PFR site did not experience soil crusting in this first year of testing.
