Manure is usually managed as dry solid manure or liquid slurries, stored in especially
Finland, Iceland, Northern Ireland, Republic of Ireland, Scotland
designed Storage Facilities or Structures. Liquid manure and wastewaters are sent to detention ponds or lagoons for settling out the solids fraction and reducing the volume through evaporation (5.1.). Lagoons also serve as a temporary storage facility for land application. However, the quantities of manure generated on the confined animal operations often exceed local crop needs and areas available for application, posing considerable challenges in P management (e.g. Sharpley et al, 1994; Sims et al, 2005; Doody et al, 2012; Doody et al, 2013; Teenstra et al, 2014).
