No-tillage (PD) has many physical, chemical and biological benefits to soil, however, some problems arise over time with the adoption of this management system, such as soil compaction, subsurface acidity and soil deficiency. deep calcium, which can restrict the root growth of crops. Aimed to evaluate the effect of the application of doses of gypsum (0, 1, 2, 4 and 6 Mg ha-1) on some chemical attributes in soil depth and soybean yield in area under PD. , without and with revolving. The experimental design was a complete randomized complete block design in a split - plot design with four replications. The area had been conducted for several years in PD, being a dystrophic Red Oxisol, with a clay texture, in Southwest Goiano, where the Ca2 +, Mg2 +, K +, effective CTC and S-SO4 2- levels were determined in the 0-5 layers., 5-10, 10-20 and 20-40 cm. It was observed that in PD without revolving the highest concentration of cations and sulfate occurred in the 0-5 cm layer, while in PD with revolving the S-SO4 2- concentrated 20-40 cm. The highest soybean yield occurred in the PD without revolving, but the gypsum doses did not influence the same. Correlations between Ca2 + and S-SO4 2- contents in relation to soybean yield were positive in the PD with revolving in the four sampled layers. Therefore, in PD without revolving, under the same conditions of this soil and without rainfall restriction, no increase in productivity is expected with the revolving and application of agricultural plaster.
