                         solo ABSTRACT: In this work, the total chemical element levels in 
                         a Rhodic Hapludox were determined using total X-ray fluorescence 
                         spectroscopy. The research aimed to create a geochemical database 
                         of soils in the southwestern region of Paran{\'a}; compare the 
                         values obtained with national and international reference values; 
                         evaluate the effect of no-tillage versus conventional tillage 
                         systems and; coverage plants on the soil geochemistry in a long 
                         term experiment. Soil collections were made in three different 
                         locations, each in three layers (0-10, 10-20 and 20-40 cm). The 
                         technique gave a quick, clean chemical digital impression of the 
                         soil which also can be used as a background for the southwestern 
                         Paran{\'a}. The levels of chemicals recommended by national and 
                         international organizations are not aligned with the levels 
                         observed in non-disturbed areas of Paran{\'a} State. The results 
                         also showed that twenty nine years after the beginning of the 
                         experiment, the natural fertility changed and that, with the 
                         substitution of native vegetation for cultivation systems, levels 
                         of some components such as SO3, MnO and Co decreased and those of 
                         others such as CaO, K2O and MgO increased. In soils for which 
                         no-tillage systems (0-10 cm) is the largest concentrations of 
                         anthropogenic substances. The conventional tillage systems gave 
                         levels very different from those found in soils under coverage 
                         plants and not significantly different between the soil layers.",
