Abstract

[automatically translated] In Sicily, an area of about 250,000 hectares, is affected by soils affected by salinity. In the laboratory, the salinity of the soil can be estimated indirectly by determining the electrical conductivity (EC) of the extract suspension of soil / water, while for its direct estimate of the pitch is spreading the use of electromagnetic induction sensors. The aim of the work was the evaluation of the spatial variability of the electrical conductivity of soils affected by salinity, with an electromagnetic sensor. The study area lies in central Sicily, in the "Complex Boscato Mustigarufi" whose soils have a different salt content. The measures, carried out in 329 points on the hillside of 200 hectares, have been interpolated using punctual kriging. From field results it showed that the EC presents considerable variability along the slope and ranges between 0.2 and 2.7 dSxm-1. In addition, the EC results of field have shown a trend of EC along the profile of some pedon investigated similar to that emerged from laboratory data. The electromagnetic sensor result is a valuable tool in the evaluation of the spatial variability of the CEA in an area where the soils are characterized by a very variable salts content
