Key Conclusions

Both Polysulphate and ICL PotashpluS proved to be highly viable sources of sulfur for soybean fertilization, increasing yield by more than 3.9% in comparison to fertilization without sulfur, and by 1.5 to 3.5% compared to other sulfur sources.

Objective

To evaluate the agronomic efficiency of Polysulphate and ICL PotashpluS as sulfur sources on the yield of soybean.

Treatments

This randomized block trial consisted of six treatments with four replications. Treatments were combinations of MAP, MOP, Polysulphate, ICL PotashpluS, single superphosphate, pastilled elemental S, and one commercial blend with MAP and sulfur in two forms, sulfate and elemental. All treatments were fertilized with 80 kg/ha P2O5, 80 kg/ha K2O and 20 kg/ha S, except the control treatment where S was not applied.

The MAP, single superphosphate, MAP+S, Polysulphate and pastilled elemental S were applied in the furrow; MOP and ICL PotashpluS were applied broadcast and pre-planting.

Results

  • Polysulphate in the furrow and ICLPotashpluS in broadcast are highly viable sources of sulfur for soybean fertilization.
  • More than 3.9% increase in soybean yield in comparison to fertilizer strategies without sulfur.
  • Compared to other sulphur sources, ICL products (Polysulphate and ICL PotashpluS) increased soybean yield in this trial by 1.5 to 3.5%.

 

Trial in Brazil demonstrates that ICLPotashpluS and Polysulphate increase soybean yield over other fertilizers
