Although farm slurry is a potentially dangerous pollutant, it can also be a very valuable asset when handled correctly, acting as a natural fertiliser and being used for animal bedding which can be returned to soil.

Despite this, farm slurry can present many challenges for farmers, not least the importance of minimising pollution and ammonia emissions, and the impending legislation associated with it. Thankfully, there are a range of methods and processes that can help to reduce its impact on the planet while also enhancing the farmer’s bottom line.

Slurry Separation

Slurry separation allows for an increase in storage while also allowing for the distribution of solids throughout the year, meaning the liquid can be stored until the time it is needed for spreading. 

In light of the upcoming legislation for storage areas due in 2027 or sooner, there’s some justification for reducing solids content stored in tanks to allow for increased liquid capacity while reducing settlement issues.

T-T Separator Range

The T-T Separator Range provides the ideal solution, increasing storage by more than 30% while reducing ammonia output. Offering separator rotation of up to 33rpm, it is capable of reducing moisture content by 38%, delivering both economic and environmental benefits from improved cost and efficiency.

Slurry Spreading and Pumping

The use of LESSE (Low Emission Slurry Spreading Equipment) is beneficial to the environment, minimising ammonia and pollution while increasing the amount of nutrient available from the slurry to the soil. 

LESSE requirements have also made farm slurry spreading increasingly demanding on farmers - and with the upcoming 2025 deadline for farmers to reduce ammonia emissions, getting prepared has become a matter of urgency.

Data coming from the DAERA (Department of Agriculture, Environment and Rural Affairs) shows that the slurry needs to be chopped to allow efficient distribution and minimise the ammonia discharge. In a comparison of slurry application systems, Shallow Injection was shown to give the best overall performance, with LESSE systems reducing the risk of nitrogen loss by up to 60% while simultaneously reducing ammonia pollution by 70- 80% through Shallow Injection.

The Cri-Man PTH Solution

Chopping prior to spreading reduces the risk of applicator blockages and means the systems can deliver the slurry more evenly.

The Cri-Man PTH Chopper chump provides the ideal solution, delivering high flow rates and spreading pressure for greater performance, increased efficiency and the further advantage of much reduced fuel costs. With the need for pre-chopping in slurry spreading, the Cri-man PTH chopper pump adds efficiency and performance to the process.

Pasteurised Bedding

Utilising the solids from farm slurry (referred to as ‘Green Bedding’) is also associated with issues around hygiene and disease transmission

Enter the HBC Biocel, a revolutionary solution for transforming slurry into comfortable and hygienic pasteurised bedding.

pasteurised bedding with hbc biocell

The introduction of the HBC Biocell into the UK has been revolutionary after great success worldwide with a process that pasteurises the solids from separated animal slurry into a comfortable sanitised alternative to straw or sawdust. Built to deliver consistent quality and sanitisation of bedding,  it works under even the toughest conditions, allowing the substitution of straw bedding. The pasteurisation process kills off the harmful bacteria and pathogens to such a degree that the bedding is considered inert and does not transmit disease.

Utilising these methods provides a significant opportunity to turn farm slurry from a liability into an asset, reducing the environmental impact and efficiency while enhancing the bottom line.
