The Benefits of Polysulphate are Clear to See

When it comes to understanding the benefits to a plant of a mineral fertiliser such as Polysulphate, there is nothing quite like seeing it with your own eyes. In a recent experiment in Brazil, 5 different fertiliser treatments were applied to maize plants. The treatments were chosen to demonstrate the effect of Polysulphate on the plants.

What is Polysulphate

Polysulphate is a unique, natural, organic, multi-fertiliser containing 4 key plant nutrients: sulphur, potassium, magnesium, and calcium. Polysulphate is a soluble, easily absorbed, cost effective answer to crop nutrition. Innovative and highly versatile, this natural, multi-nutrient mineral is low in chloride and crop safe, suitable for use alone or in blends and compound fertilisers.

Testing Different Fertiliser Treatments

There are 5 different treatments under examination:

• Treatment 1 – No fertilisation
• Treatment 2 – Granular Polysulphate
• Treatment 3 – Standard Polysulphate
• Treatment 4 – Solution (lacking K, Mg, Ca and S)
• Treatment 5 – Solution + calcium sulphate, magnesium sulphate, and potash sulphate

The photographs, taken when the plants are 15 days old, show the dramatic differences between a plant with no fertilisation and a plant with Polysulphate.

The maize plant grown with Standard Polysulphate is taller, bigger and has healthier looking leaves than those in each of the other treatments.
