K-PluS combines Viafos’ popular V10 and Potash22 products meaning users gain the collective benefit of a part fast, part slow release of guano phosphate, potassium and sulphur.

KPlus crop

Viafos K-PluS offers:

  • offers a slow partial liming effect on the soil solution 
  • lifts soil pH – benefiting soil biology and chemistry
  • has a high level of amorphous Silica (SiO2) – which can benefit grain crops and plant pest and disease resistance
  • is a more beneficial form of K compared to other forms including synthetically produced potassium 
  • combines fast release with a small amount of longer-term steady supply potassium and without the harsh effect of potassium chloride on sensitive plant roots or salinity of the soil solution.
