It may be executed in crops making use of mechanized remedy models similar to All those utilized for industrial wastewater. In which land is accessible for ponds, settling basins and facultative lagoons could have reduce operational expenses for seasonal use disorders from breeding or harvest cycles.[thirteen]: six–eight Animal slurries are frequently handled by containment in anaerobic lagoons prior to disposal by spray or trickle software to grassland.
