The Benefits of Polysulphate are Clear to See
Polysulphate's natural combination of key nutrients including sulphate, potassium, magnesium, and calcium make it an ideal choice of fertiliser.
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.
