Sovereign Sulphur is a granular product containing 90% elemental sulphur & 10% bentonie clay. It can be used at low rates to deliver sulphur to the crop or at higher rates to correct the soil pH. It breaksdown and washes into the soil quite rapidly, but requires warm soils to become useable to the plant.
At the rates that Sulphur is applied for nutritional purposes, the effect on soil pH would be negligible. However, in certain circumstances, it is beneficial to lower the pH of soil. Common reasons for lowering a soil pH may include to establish Heather or other acid loving plants, reducing common scab in potatoes or in grassland and lawns where the optimum pH is 6.5.
Sovereign Sulphur has also been extensively trialled for the reduction of worm casts in finre turf. We have seen excellent results when used at 100kg per hectare every month for several months. This is a preventative treatment which pushes the worms deeper down. Please note, these granules can take a long time to break down. We do have a mini-granule option if required.
Nutrient deficiency is common on neutral soils, alkaline soils or soils with excessive lime. Availability of essential nutrients is often lower due to the high pH of these soils. Temporary rectification of these issues can be achieved by foliar applications. However, on small areas of land where crop production is intensive, it is the more practical, permanent and advisable solution to reduce the pH of the soil, especially if it does not require significant lowering.
This is a granular product which is suitable for hand or machine spreading. It can be incorporated into the soil or left to disolve on the surface. For larger areas this product is also available in 1 ton bags.

Sulphur compounds such as Sovereign Sulphur can be used on soils in order to provide calcium or release calcium that was previously insoluble. This calcium replaces the absorbed sodium on the colloid. The sodium then combines with the sulphate ion to form a soluble sulphate which will be removed through leaching of the soil.
By using this product for soil amendment, nutrients will be more widely available to aid the growth of plants. Crop yield, quality and profitability of the plants will be increased as a result.
- For alkaline soil apply Soverign Sulphur
- For acidic soil apply Granulated Lime
- The application of Iron Sulphate can also help reduce the pH
