MicroZyme slurry improvers have been launched in the UK by slurry specialist Tramspread. The biological slurry additive reduces solids and ammonia emissions whilst improving nitrogen retention. Managing director, Terry Baker says:

“MicroZyme products will reduce emissions and improve the value of slurry to the crop and soil. The unique bacteria in MicroZyme R (ruminant) and MicroZyme S (swine) break down fibre, starch, pectins, fats and protein residues to decrease solids and lower harmful emissions.”

The government’s Clean Air Strategy has demanded that emissions from slurry be cut by maintaining slurry stores and applying slurry more accurately. It is expected that splash plates will be banned in 2025 and that all slurry should be covered by 2027.

“These products will help farmers to meet these targets and will also make applying slurry more efficient. Slurry treated with MicroZyme requires less agitation and will require less fuel to pump out. It will also make the slurry more homogenous which will improve application accuracy, especially with trailing shoe or dribble bar applicators,” adds Mr Baker.

Degradative enzymes in MicroZyme begin to act on the slurry immediately to decrease solids and reduce crust formation. This will also reduce the build-up of sediment that can lead to some storage, such as lagoons, reducing in capacity and becoming unsustainable.

The N, P and K value of the slurry and the uptake potential for the crop will also be improved following treatment. “This will make the slurry more suited to multi-cut silage systems and will reduce the need for bought-in fertiliser because the slurry will have more value to the crop and can be absorbed by the crop and the soil more effectively,” he says.

Trials have shown that slurry treated with MicroZyme has lower levels of coliforms and E. coli. The Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) are also lower. This improves nitrogen retention and reduces sulphide and ammonia levels.

“These products are an important development to helping manage slurry both in storage and during application. For farmers looking to improve the value of their slurry and reduce emissions it represents a cost-effective solution that is easy to manage and will bring immediate benefits,” he concludes.
