Abstract: The use of treated domestic sewage (TDS) in agriculture by drip irrigation in the soil subsurface can serve as an extra treatment and also provide higher availability of water and nutrients to plant roots. It represents safer and healthier cultivation for crops, producers and consumers, and allows the direction of better quality water for domestic consumption. This study aimed to analyze the possible effects of TDS irrigation on chemical and biological properties of the soil in an orange plantation. The experiment was conducted on Lagoa Bonita Farm, at the Adventist University Center of São Paulo - UNASP - Engenheiro Coelho Campus, SP. A block design with three replications was used in the following treatments: soil irrigated with TDS on the surface, soil irrigated with TDS in the subsurface, and soil with no irrigation. Soil samples were collected for chemical and biological analyzes, as well as samples of the treated domestic sewage used. The TDS characteristics were within the parameters allowed by law. Considering the chemical parameters and the types of irrigation analyzed, the highest results observed were: K: 11 mmolc.dm3, Ca: 30 mmolc.dm3, Mg: 7 mmolc.dm3, and pH: 5.5.
