Plant Nutrients in Municipal Wastewater
Municipal wastewater (sewage effluent) from an activated sludge sewage treatment plant contains most of the major plant nutrients needed for plant growth. It contains more nitrogen, phosphorous, and potassium, the principal fertilizer elements needed for growth, than does most irrigation water from rivers, dams, and wells. In desert environments, if municipal wastewater is used instead of conventional irrigation water, it provides more nitrogen, which is the fertilizer plant nutrient needed most for plant growth, than is usually necessary for favorable crop production (Sopper and Kardos 1973; Fuller and Tucker 1977).
