Making the most of Organic Material

Slurries and farm yard manures represent a hugely valuable and often under- utilised resource on many dairy farms. Understanding their nutrient values could help reduce reliance on bought in fertiliser and save money.

For example, a typical 200 cow dairy herd produces muck containing about 1,750kg of nitrogen, 1,200kg of phosphate and 4,400kg of potash during a six month winter. That’s worth £3,875 when surface applied.

Taking into account the nutrient value of organic materials when applied with bagged fertiliser is also important for overall performance, as excess nitrogen could result in poor silage fermentation and environmental risk.

This Dairy Insight summaries the how savings can be made through good utilisation of organic material .
