The present work deals with the “Decision Support System-Computer Program,” a tool that can be used for the reuse of treated wastewater and biosolids in agriculture. It has been developed by the research team of the Hellenic Open University, School of Science and Technology, Laboratory of Sustainable Waste Management. The basic aim of this tool being the following: (a) Exploitation of treated wastewater and biosolid reuse, in agriculture. (b) The safe reuse of treated wastewater and biosolids and optimization of soil fertility and productivity, minimizing human health risk. (c) Improvement of soil physical characteristic by increasing its organic matter content. (d) Rational crop fertilization, suggesting to user the right kind and the optimum levels of fertilizers to be applied to crops and accomplishment of economy in the use of inorganic fertilization of crops. (e) Supply plants with nutrients and irrigation water. (f) Optimize crop fertilization, reducing the fertilizer cost g- forecast and prevent soil pollution with heavy metals. (h) Optimize crop production quantitatively and qualitatively. (j) Protect agricultural soils from over accumulation of biosolids and the surface waters from heavy metals and nutrients. (k) Relieve of the environment from the pressure exerted by the accumulation of heavy metals and toxic substances. (l) Optimize environmental and life quality.
