Wastewater is a rich source of plant food nutrients. Empirical studies, presented in an earlier section of this paper, show that the impact of wastewater irrigation on yield, varies from crop to crop. If
the crops are undersupplied with essential plant food nutrients, wastewater irrigation will act as a
supplemental source of fertilizer thus increasing crop yields. Alternatively, if plant food nutrients
delivered through wastewater irrigation result in over supply of nutrients, yields may negatively
be affected. In the absence of any chemical fertilizer application, wastewater nutrients will act as
a sole source of fertilizer, delivering savings in fertilizer cost. Thus, from an economic standpoint wastewater irrigation may have a three-fold effect on crops: (1) higher yields, (2) source of
irrigation water, and (3) fertilizer value
