Evaluación del potencial de la especie apio (Apium graveolens) para la recuperación de suelos degradados por salinización con carbonatos

Abstract

In the present study, soil samples were taken from the municipality of Jerusalén, Cundinamarca, since it presents soils with conditions of severe and high salinity, and pH as high between 7.5-8.4. In addition to this, 47.1% of the soil was identified calcareous. In the sampled soils, the ability of celery (Apium graveolens) to remove carbonates was evaluated, where an experimental design was carried out for high, medium and low salinity levels; 6 mattresses were analyzed, 2 for each level and their respective controls. In each one, 8 seedlings were sown for a total of 48, the sampling was carried out on the 7th of each month during the 4 months of study. Physicochemical analyses were performed for each salinity level such as pH, CE (Electrical Conductivity), DA (Bulk Density), Ds (Specific Density),% EP (Porosity),% W (Humidity),% MO (Organic Matter), texture and concentration of %CaCO3; plant physical characteristics such as stem growth, root growth, the physical appearance of the leaves, colour change and presence of pests were also followed up. The method used to calculate the %CaCO3 was total carbonates, through multivariate analysis it was evidenced that there are no clear trends with respect to time and levels; but if there is evidence of increases between the concentrations, where the univariate analysis of variance is significant for the variable presence of plants with 0.056 accepting the alternative hypothesis. From the above, it is concluded that the best development level for the celery species (Apium graveolens) is due to the average salinity level, as a result of its adaptability in the saline soil; on the other hand, there are no reductions in the concentrations of %CaCO3 in the salinity levels analyzed.
