Lower emissions and improved manure quality. Biological acidification of manure is showing promising results in the Netherlands and abroad. ForFarmers is therefore conducting field trials on Dutch cattle farms with the aim of achieving official recognition of this technique as a measure to reduce emissions.
In this process, a sugar-rich by-product, such as molasses, is added to manure in the manure cellar. Natural fermentation produces lactic acid, which lowers the pH to below 5.5. This inhibits the formation of ammonia and methane. The result is lower emissions in the barn and during spreading, as well as improved manure quality. An added bonus is that during fermentation, acidified manure produces more gas.
Robert Meijer, Director of Marketing and Communications for Ruminants: “Biological acidification is a promising solution for reducing emissions. The combination of positive field results and international experience makes rapid implementation feasible.”
