Product description

Its unique advantage is its additional natural content of other nutrients. Polysulphate® is derived from a polyhalite rock layer located more than 1,000 meters below the North Sea floor off the coast of North Yorkshire, UK. The deposits formed 260 million years ago are located 150-170 m below the potash seam at the Cleveland Potash Boulby Mine.

The main layer of polyhalite was reached in September 2010, bringing the first samples to the surface. It is estimated that this source may contain approximately one billion tons of raw material

Polysulphate (the trade name of this polyhalite fertilizer) is available in both granular and powder form. The 2-4 mm granular product has excellent spreading properties and is an ideal product to be used together with nitrogen fertilizers.

 

Composition:

48% SO3 in the form of sulfate
14% K2O from Potash Sulphate
6% MgO from magnesium sulfate
17% CaO from calcium sulfate


The benefits of potassium, magnesium and calcium
In addition to sulfur, Polysulphate also contains valuable ingredients such as potassium (K2O), magnesium (MgO) and calcium (CaO).

Potassium should be regularly introduced into the soil based on the analysis of its condition and due to its removal from the field along with the crop. Research has shown that soil reserves are declining, with more and more arable soils reaching index 0 or 1. Most of the potassium in the harvested crop is in the straw. So, when selling straw is economically viable, the potassium dose should be increased to make up for the shortage. The potassium in Polysulphate complements standard fertilization.

Magnesium is often only used for certain profitable crops and vegetables. This macronutrient is part of the chlorophyll of all green plants and is essential for photosynthesis. It is removed in significant amounts during the harvest of all crops. The use of Polysulphate will supplement this ingredient that is usually overlooked.

The fourth ingredient of Polysulphate is calcium, which means that this fertilizer contains no other ingredients than those with nutritional value. Calcium is responsible for proper cell division and strengthening the cell walls. Polysulphate helps to maintain the necessary calcium reserves in the soil.

Polysulphate is especially suitable for crops that prefer a low level of chloride in the soil such as tobacco, grapes and other fruits and where a higher dry matter content is desired, e.g. in potatoes.

 

Need to use sulfur fertilizer

Sulphates are now considered to be the main fertilizing ingredient for crops and grassland. However, systematic sulphate fertilization is not yet used on most arable lands.

Sulfur deficiency is a common problem today. In Great Britain, the yield response to the use of sulfur in the cultivation of wheat
winter can be up to 30% more, and on average it is 6%. In vegetable crops
cruciferous benefits are greater - studies have shown that winter oilseed rape can yield higher yields of up to 80%.

However, despite such examples, the use of sulphates in crops is low. Only 42% of the cereals receive systematic fertilization. In oilseed rape, despite the proven benefits, only 65% ​​of the crops receive the amount of sulphate they need. While almost all crops would benefit, it is possible that the use of sulfur fertilizers has been limited due to the lack of cheap, easy-to-use sulfate fertilizers.

In the past, arable crops and grasslands in industrialized countries never required the use of sulfur. Burning coal has always provided a lot of sulfur via precipitation.

Pollution regulations mean that this rainfall is only a fraction of what it used to be. As a result, large acres of cultivated fields are sulfur-deficient, especially those with lighter soils or less rainfall.

Nitrogen (N) and sulfur (S) are essential components of plant and animal proteins. As sulfur is no longer readily available from the atmosphere, in areas where nitrogen fertilization is applied, there will be a need for a sulphate balancing fertilizer to ensure high yields and quality.

 

Action of Polysulphate

Studies conducted in independent and independent research centers have shown that Polysulphate ™ works as well as the best sources of its main ingredients available. It is well adapted to a spreading width of 24 meters and more.

Experiments with Polysulphate have focused on checking that its main nutrients - sulfur, potassium and magnesium - are readily available to the plant. Plants were grown in pots and fertilized with standard sources of pure potassium and magnesium sulfate or with Polysulphate fertilizer.

The uptake of nutrients from the Polysulphate fertilizer by the plants was as good, if not better, than that of the standard fertilizers applied in the field. The results confirm the effectiveness of Polysulphate as a multi-component fertilizer.

 

Get the best out of Polysulphate

Polysul

phate ™ has a number of significant advantages that make it an excellent offer for farmers among sulphate fertilizers. Polysulphate ™ offers arable crops to use their full potential.

Main features of Polysulphate:
Easily available, soluble, in the form of sulphates, for immediate use
A new, granular form of sulfur, offering flexibility in individual dose adjustment to the needs of a given field
Concentrated, thanks to which it has low storage requirements, it spreads quickly
A source of potassium, magnesium and calcium which is an added bonus
Low chloride content, which makes it suitable for chloride-sensitive crops
It is harmless to the environment as it is used in its natural form - no processing or by-products, it does not acidify the soil
Originating in Great Britain, with a guaranteed safe supply of a low-carbon product
Recommendations for arable crops
Polysulphate can be used once, in the spring, at the beginning of the growing season. The aim is to adjust the plants' sulfur requirements to their nitrogen needs. Where nitrogen doses are different, e.g. in precision farming systems, Polysulphate fertilization can be individually varied to best match the amount of sulfur to the amount of nitrogen applied.

Cereals and oilseeds
Use as a simple fertilizer at the beginning of spring vegetation
Easily accessible, the crop will take up the fertilizer along with nitrogen during the spring growing season
Use for oilseeds to optimize yield and protein and oil synthesis
Use in bread wheat to ensure high-quality yields and protein in the grain
Use in the cultivation of malting barley, ensuring higher yields of high quality
Pea
Apply directly to the substrate or soon after emergence
Nitrogen-free fertilizer, providing crops with easily digestible sulfur
Used by the plant at an early stage to stimulate the nitrogen fixation process that takes place in the root nodules and for protein synthesis in the plant
Cruciferous vegetables
Cruciferous vegetable crops have been shown to be particularly responsive to Polysulphate
Use as basic fertilization, especially on light soils at high risk
Recommendations for livestock producers
Fertilization with manure and slurry should not be regarded as providing a reliable source of available sulfur. However, they work well as sources of sulfur in soil.

For this reason, Polysulphate should be used based on nitrogen requirements in order to achieve optimal grass growth during the season with the correct N: S ratio.

Mowed pastures
Use after each silage mowing to replenish the nitrogen uptake and maintain the N: S ratio.
Lighter soils may also require fertilization at the beginning of spring.
Pastures graze
Use in a rotation system after the animals have moved to another quarters
If animals are grazed continuously without rotation, especially in lighter soils, apply early in the beginning of spring.
Clover pastures
Provides excellent sulfur increase for late-growing clover
Use during spring vegetation - earlier growing ryegrass absorbs sulfur resources from the soil.

High value, low environmental impact

Naturally available polyhalite (marketed as a fertilizer under the name Polysulphate ™) is mined in the UK and has a low carbon footprint. Provides reliable, high value with minimal environmental impact.

Unlike mixed or complex fertilizers, Polysulphate is available in its natural state. It is mined, crushed, inspected and packaged directly, without the use of chemical separation or other industrial processes.

It is therefore an ideal natural source of ingredients for all crops, especially brassicas, grains, legumes, clover-rich pastures and silage crops.

The low content of chlorine makes it ideal for use in chlorine-sensitive crops.

Due to the natural production process, Polysulphate is a low carbon dioxide fertilizer. This helps producers meet certain carbon emission standards required by retailers and some food processors.

The deposits of this raw material, mined in Great Britain, are estimated at one billion tons. The global demand for sulfur fertilizers is increasing, which is why Polysulphate provides farmers in Europe and the world with a reliable source of this raw material instead of a by-product.
