The ability to boost manure nitrogen content by 6kg/cow/year and cut the fertiliser bill by over £5/cow is the significant benefit from a new, natural mineral-based product that can be added directly to slurry.

Viscolight can be easily added to the slurry - either via the reception pit, channels or slats, or directly into the lagoon or storage tower.

Viscolight is a powder-based additive with the potential to increase slurry nitrogen by 300g/tonne. It will also improve manure handling considerably, claims UK distributor C&H Nutrition.

“Viscolight breaks down hard crusts and improves slurry nitrogen content by slackening and binding free ammonia. The end result is a higher value fertiliser and more homogeneous slurry that flows better making it much easier to handle,” says product manager Jessica Hassall.

“As well as promoting a more fluid mix of sediment and floating layers in the slurry storage tank – cutting the time and diesel costs of agitation, pumping and spreading – the natural additive will also reduce manure and dirty water odour by up to 50%.”

Jessica Hassall says Viscolight can be easily added to the slurry – either via the reception pit, channels or slats, or directly into the lagoon or storage tower. “The mixing rate is as little as 20g/tonne of slurry, which for a 100 cow herd equates to an annual product requirement of only 40kg per year. “

C&H Nutrition calculates that even after the cost of Viscolight, a 100 cow herd can expect to be around _250 better off as a result of savings on the fertiliser bill. New to the UK – but widely used successfully in Denmark where it is also approved for use on organic farms – Viscolight is available through the agricultural merchant trade and further details are available on 01928 793090.
