ABSTRACT Salinization is one of the main problems of soil degradation in arid and semiarid areas, causing a reduction of soil quality, declining yield and productivity, and even land abandonment. The aim of this study was to evaluate the effect of different land uses, particularly agricultural use in the salt content in soil. The study area is located in the surroundings of Murcia city (SE Spain), with an surface of 100 km2, with high agricultural productivity. In order to determine salt content in soil, E.C. was measured in the 1:5 ratio. The results showed that the study area is saline, being the salinity higher when anthropogenic activity is more severe. Agricultural lands present the widest range of data, probably due to the application of poor quality irrigation water, fertilizers and livestock waste. Supporting this hypothesis, spatial distribution showed that the salinity is clearly located in the agricultural area. Detailed studies will be useful to understand the salinization process in order to implement measures to control and reduce salinity.
