  abstract = {{T}he objective of this work was to evaluate ion concentrations in an {O}xisol solution, in plots subjected to different management systems. {C}ontinuous crop and pasture, and the integrated crop-livestock management system were evaluated. {T}he experiment started in 1991, and the soil solutions were collected in 2005 and 2006. {C}eramic cups were installed at 20 and 150 cm soil depths, and the solutions were extracted six times each year. {T}he concentrations of {C}l(-), {SO}(4)(2-), {NO}(3)(-), {H}(2){PO}(4)(-), {K}(+), {M}g(2+), and {C}a(2+) were determined. {I}rrespective of the depths and cropping systems considered, the concentrations of ions into the soil solutions, in decreasing order, were: {NO}(3)(-)>{C}l(-)>{SO}(4)(2-)>{H}(2){PO}(4)(-) and {C}a(2)(+) >{K}(+) >{M}g(2+). {A}mong the cropping systems, the ion concentrations in the soil solution was higher in the continuous crop under conventional tillage, followed by the continuous crop under no-tillage, and finally by the integrated crop-livestock system and the continuous pasture. {A}t 150 cm depth, the ion concentrations in soil solutions under continuous pasture and integrated crop-livestock system were always low, which indicates a low leaching risk.},
