Vinasse and biocarbon are used as recuperators of saline-sodium soils. The objective was to analyze remediation process of saline-sodium soils in the district of Tambo Grande, Piura. A sample of 10 kg of saline soil was used and it was taken to the laboratory for testing. Two columns of ground were built; at the lower end of each column was placed a leachate collecting vessel. The columns were divided into two treatments: the first was treated with water and the second was treated with vinasse; the conditions of the field washing were simulated for each column, periodically the leachates were analyzed and at the end of one month of treatment was performed analysis each of the soils in the columns. The final results indicated a decrease PSI (0.49), sodium (3.52 meq/L), Electrical Conductivity (1.46 dS/m), as well as an increase of nutrients mainly potassium (20 meq/L) and percentage of organic matter (2.17%). To evaluate the effectiveness of the soil, tests were carried out in pots with a culture called wild radish (raphanus sativus) in four pots of which one was a blank sample (without any treatment) and the remaining three had the soil treated with vinasse with different proportions of (25%, 50%, 75% by weight), for which the growth (cm) and vigor (number of leaves, number of shoots) of the crop were taken as parameters. The results indicated a better growth in the treatment with 25% of biochar, also evidenced the lack of growth in the control treatment.
