Slurry tank covers are becoming increasingly popular, not least because there is new legislation which indicates that tank covers are now a necessary addition to a slurry tank. There are, however, many advantages of tank covers to farmers who manage slurry. It is necessary to have a fixed cover or a natural floating layer in order to reduce emissions, but this is not the only benefit of a slurry tank cover – there are financial benefits too.
Reduced evaporation of nitrogen – without a cover, around 10% of the nitrogen content of slurry can be lost. Nitrogen-rich fertiliser helps crops to grow. Covering your slurry tank will lead to better utilisation of fertiliser value, you will also make savings on the purchase of fertiliser and benefit from a better autumn yield.
Elimination of rainwater from the tank – No matter where you are in the UK, an uncovered tank is going to take on rainwater. Rainwater not only dilutes the slurry but also creates extra work to empty the store. Covering your slurry tank will lead to a more effective use of the storage facility.
Reduction of odor nuisances – A tank cover helps to reduce the amount of odor coming from the slurry tank. This is a benefit for not only the farmers, but also to the neighbouring homes or businesses.
More options for locating slurry tanks – A tank cover allows you to control the emissions and odor that are emitted from the slurry tank. This may allow sites to be developed that otherwise would be unacceptable.
A tank cover can reduce the size of tank required – A tank cover can significantly reduce the size of slurry tank required, by allowing rain water to flow away rather than mix with the contents of the slurry tank.
Save on water costs – When you have a tank cover, there is the potential to collect and use clean rainwater, therefore saving on water costs.
