GIS maps were developed to assist the decision on the suitability of land to accept pistachio wastewater. Suitability maps were developed for each one of the soil parameters that were found to be affected mostly by pistachio wastes, as well as for the natural areas characteristics (i.e. slope, drainage, etc). Considering the specific limitations for these characteristics and parameters, the overall Land Suitability Map for pistachio wastewater landspreading was developed. The methodology for land evaluation and categorization into suitability classes was that of FAO (1976)#. Maps are included in the Cultivation Management Software to assist decision making regarding reuse or disposal of pistachio wastewater.
