BioAgSoP is a sulphate of potash fertiliser. The sulphur content improves nutrient cycling and uptake and provides benefits to yield and fruit quality.

Potassium plays a vital role in photosynthesis, starch accumulation, protein synthesis, controlling ionic balance within the plant, metabolism of carbohydrates, disease suppression, and improving the plant’s ability to withstand drought and frost tolerance.

As an organically certified product, it is ideal as a source of potassium for intensive organic grazing operations such as dairies.
