Slurry Sol

Slurry Sol is the ideal treatment for slurry to improve its quality and reduce crusting issues.

Reduced Crusting
Slurry sol uses a combination of enzymes and bacteria to break down fibrous material and retain more nutrients in the slurry. The enzymes have an immediate impact on this breakdown, breaking the bonds that hold the fibres together. The bacteria are the key to long term effectiveness in slurry over a winter. The bacteria require both a carbon source and a nitrogen source to allow them to grow. The carbon comes from the organic material in the slurry and the nitrogen comes from the ammonia in the slurry. The advantages of this are that the solid material contains the carbon and this reduces the crusting and caking found in slurry. The second is that the ammonia which would otherwise be lost is tied up as microbial protein which is then safe from volatilisation during storage or spreading.

The pictures show the increased activity and reduction in solid material in a controlled environment.

More Nitrogen
The ammonia level in the slurry is reduced by Slurry Sol. The benefit of this is that the nitrogen is tied up to reduce losses. The Nitrogen is stored as microbial protein which cannot be lost to the atmosphere. When spread the Nitrogen is in an ideal form to feed the soil microbes. This in turn leads to improved soil health, less scorching of the sword and better regrowth.

The above trial result shows the reduction in ammonia as the bacteria consume the ammonia level. The results in an increase in retained Nitrogen in the slurry.

Less Odour
The odour level in the slurry is reduced due to the bacteria in Slurry Sol reducing the Ammonia level and breaking down other sulphurous compounds in the slurry. The result is less odour in sheds with underfloor slatted slurry stores. Less odour from outdoor stores and less odour at spreading time. The reduced odour is particularly obvious where closed housing is used on piggeries. The lower ammonia level will additionally improve animal health and performance.


  • Reduces crusting
  • Reduces blockages
  • Retains more Nitrogen
  • Lower odour
  • Slurry more consistent at spreading
  • Reduction of flies
  • Healthier Soil Structure
  • Less scorch
  • Better growth of swords

Use 1kg of Slurry Sol per 44,000 gals or 200m3 of store capacity.

Add Slurry Sol to the store based on the volume of the store. Distribute as well as possible to encourage best performance. Agitation is an ideal way to ensure the bacteria are well spread.

Where under slat stores are being treated mix the Slurry Sol in plenty of water and pour through the slats, if possible create a pool on top of the crust.

Regular agitation during the season will be rewarded with additional activity and less work at spreading time.
