Yield Increase
ICL PotashpluS increases potato yield and tuber dry matter, while also improving consistency in tuber sizes.
North Yorkshire, UK 2018

Key Conclusions
This UK potato trial compared 2 potassium sources, ICL PotashpluS and MOP, and found that ICL PotashpluS increased potato yield and tuber dry matter, while also improving consistency in tuber sizes.
Objective
To investigate how ICL PotashpluS compares to muriate of potash (KCl, MOP) as a source of potassium for processing potatoes (Solanum tuberosum).

ICL PotashpluS
Assessments
Yield and tuber dry matter (% DM)
Treatments
- This was a split field trial.
- ICL PotashpluS and MOP were applied to provide the same application rate of potassium: 340 kg K2O/ha.
- Both fertilizers were broadcast and incorporated prior to planting.

- Both fertilizers were broadcast and incorporated prior to planting.
Results
- ICL PotashpluS gave an 8% increase in yield over MOP. This is attributed to the soluble magnesium, sulfur and calcium supplied by ICL PotashpluS, even when the soil was not magnesium deficient.
- The tuber dry matter was higher in the ICL PotashpluS treatment (20.6%) than where MOP was applied (19.8%). Dry matter is a valuable benefit for processing potatoes.
- The ICL PotashpluS potato tubers were judged to be more consistent in size, showing less variation.
ICL PotashpluS produces an 8% increase in potato yield compared to MOP.
ICL PotashpluS increased potato dry matter compared to MOP.
