The leachate from landfills is a highly impactful liquid waste to the environment, making it essential to conducting research that provide a better and more precise characterization. In this context, it objectified with the work to analyze the effect of the application of landfill leachate (PATS) and water supply dosages in altering the levels of nitrogen, phosphorus and potassium in an argisol grown with sunflower. To carry out this work, an experimental area was set up and the following treatments were used: T1 - 100% of water from the supply network (control); T2 - 80% of water from the supply network and 20% of PATS; T3 - 60% water supply and 40% PATS; T4 - 40% water supply and 60% PATS; and, T5 - 20% water supply and 80% PATS. Only the P values were significantly influenced by the PATS dosages applied in interaction with the application time and in relation to the two soil depths studied. The levels of N decreased considerably over the treatment application time. Along the soil profile, the values of N and P decreased. K concentrations did not show a variation pattern, due to the variation in PATS.
