Introduction. Saline soils are a threat to crop productivity, which occurs in the rice-growing areas of Ecuador. Objective. To assess the changes in the chemical properties of 3 experimental soils caused by the effect of the application of mineral amendments, particularly the effects on the variables related to salinity. Materials and methods. The calcium amendments tested (CaCO3, Ca(OH)2, CaSO4.2H2O, Ca2SiO4) and a zeolite, were applied in five doses to the rice crop. The experimental design was completely randomized, with a 3 x 5 x 5 x 3 factorial arrangement of the treatments. Each treatment was repeated three times. Results. The treatments caused changes in the Electric Conductivity (EC) and pH of the soil solution and in soil fertility. The salinity of the soils in the study area is due to the presence of Na+, K+, Ca2+ and mainly Mg2+. Conclusions. the use of amendments: CaSO4, zeolite and Ca(OH)2, improved the chemical properties of the soils by decreasing the EC of the soil solution.
