A systematic review was conducted in this study with the aim of analyzing soil salinization in Latin America. Manuscripts published in the region over the past ten years in both English and Spanish that had undergone blind peer review in journals indexed in the databases of Copernicus Publications, Nature, Science Direct, Scielo, and Redalyc were taken into consideration. Soil salinity was discovered to be a growing environmental limitation in at least 9 of the 32 countries that make up the Latin American region. Secondary salinization spreads as a result of changes in land use brought on by the expansion of the agricultural frontier, poor irrigation management using low-quality water, and excessive use of chemical fertilizers, among other things.
