Many lagoon systems produce liquid waste water can be added to slurries in order to handle it as liquid waste this material can be moved by irrigation systems liquid handling lowers the labor per volume these systems have a higher initial cost these systems present less problems with field accessibility and compaction of farmland. Compaction can occur when heavy equipment is driven over wet ground.
Compaction inhibits crop growth by preventing root growth.
Oxygen is usually pumped in or is incorporated in the liquid as it flows over a substrate of some kind. Evaporation of water from a lagoon leaves the salt and other minerals behind. Over time the salinity of a pit can increase to critical levels salt levels above 5000 ppm will inhibit bacterial degradation, thus inhibiting the function of the lagoon periodic removal of a portion of the volume will help alleviate this problem. C. Seepage Some soil types allow seepage of lagoon wastes into soil. This is known as leaching and if serious can lead to contamination of wells, waterways, etc.
