Pollution and Waste
The fermentation process of silo or pit silage releases liquid. Silo effluent contains nitric acid (HNO3), which is corrosive. It can also contaminate water courses unless collected and treated – the high nutrient content can lead to eutrophication (growth of bacterial or algal blooms).
Plastic sheeting used for sealing pit or baled silage needs proper disposal, and some areas have recycling schemes for it.
