Description:
The Calumet land reclamation project developed design criteria for applying liquid fertilizer (sludge) to land and demonstrated the beneficial and economic use of it in raising crops. The scope of the project included developing a pipeline system to transport liquid fertilizer to the application site, determining yields, analyzing plant tissue of the crops grown, observing the soil changes effected by the liquid fertilizer application, and monitoring the ground and surface water of the application site. The pipeline was built and transported liquid fertilizer from the lagoons to the application site. The application of liquid fertilizer increased the yields of wheat and corn, increased the concentration of plant nutrients in the plant tissue, and effected organic improvements in the soil. Analysis of the leachate from the piezometers showed that groundwater constituents fluctuated, partly because surface water seeped through the perforations in the piezometers at the soil surface. This pollution did not reach the groundwater aquifer sampled from a deep well constructed of solid wall pipe.
