Soil salinization and sodification, caused by inadequate land management, is one of the main threats to the semiarid agroecosystems. It is essential to investigate saline levels under different land-use conditions to maintain the sustainability of agricultural production. The main objective of this study was to diagnose the salinity status of the soil in different land-use conditions in the semiarid region of Northeast Brazil. Soil samples were collected in the surface layer (0-5 cm) of three different land-use conditions: areas of low salinity (native vegetation - Caatinga), areas of different saline levels (cultivated areas), and areas of very high salinity (desertified by salinity), and compared regarding the chemical attributes of the soils by descriptive and multivariate analysis. The results showed that sodium and chloride were the predominant soluble ions in cultivated and desertified areas due to saline waters commonly used in the study region. Increases in electrical conductivity values of 1219 and 23207% were observed for cultivated and desertified areas, respectively, compared to areas of native vegetation. The principal component analysis contributed to identifying parameters responsible for the variation in soil salinity, and the second factor identified that percentage of exchangeable sodium, electrical conductivity, and exchangeable and soluble sodium plays an essential role in soil desertification. However, calcium, magnesium, sodium, and chloride ions correlated positively with variables that degrade soils - EC, ESP, and SAR. We also found that in desertified areas, in addition to chloride, sulfate is also present in expressive levels, and due to the strong associations with calcium, magnesium, and sodium, our study suggests that in addition to the free forms of these ions, the forms of chlorides and sulfates of calcium, magnesium, and sodium also effectively contribute to the degradation of the areas. The combination of multivariate analysis × geochemistry × laboratory techniques was a valuable tool to identify and monitor saline levels in converting uncultivated to cultivated areas and from cultivated areas to desertified areas.

Abstract A fast method for the simultaneous quantitative determination of 16 phenolic compounds in grape juice by UPLC-MS was developed and validated. Run time was 4.5!min and the method proved to be specific, linear (r > 0.9961), precise (RSD < 5%), accurate (recovery range was under ± 5%) and sensitive with a limit of detection ranging from 0.45 to 35.34!"g L−1 and limit of quantification ranging from 1.35 to 107.08!"g L−1. The validated method was used to characterize 49 grape juice samples which were produced with different grape varieties. Anthocyanins were the compounds present in the highest amounts on the analyzed samples and BRS-Violeta was the cultivar that presented the highest quantity of phenolic compounds in its juice. Exploratory analysis of the obtained results from the characterization of grape juice samples was performed and a tendency to form groups according to the grape variety used in the elaboration of each juice was observed. Results confirmed that the UPLC-MS method is effective and suitable for the determination of phenolic compounds in grape juice.
