According to preliminary data of the Natural Resources Institute Finland (Luke), approximately seven per cent of all farms exported manure outside the farm in 2016. This figure is at the same level as in the previous statistics from 2010. Nearly five per cent of all farms use processing methods that change the properties of manure.
Solid manure and slurry were exported to an equal extent. Approximately 11 per cent of all farms imported manure. This means that the number of importing farms was higher than that of exporting farms. Approximately two million tons of manure were transported between farms.
Composting is the most common processing method
– Composting solid manure was the most common processing method to change the properties of manure. It was used on nearly four per cent of all farms. Other methods, such as separation, aeration or fermentation, were used by less than 0.5 per cent of all farms,” says senior scientist Pasi Mattila from Luke.
Most farms that use processing methods process all or most of their manure. The average proportion of processed manure from all manure on farms was two thirds or higher, depending on the method.
Final data will be completed next year
The preliminary data was collected from farmers during the Farm Structure Survey in autumn and winter 2016–2017. This data published is preliminary. Final results that also include information by region and production sector will be published next year.
