Digested slurry as a fertilizer for biogas ley

Summary

Digested slurry injected produces in this case comparable yields with mineral fertiliser. Because the primary growth is the largest and of the best quality it should be used for feed as the first option. The re-growths could then be used as a co-substrate in biogas reactors. Digested slurry is a good fertiliser for leys when injected. Injection of non-digested slurry reduces the ammonia emissions and leaching of soluble phosphorus but the significance of the low performance of nitrogen leaves open its fate.
