Resumen
This study has the purpose to test the effectiveness of the lime mud (residue of the pulp and paper industry), as corrective of soil acidity. The lime mud is a residue derived of the Causticizing process in companies of pulp and paper. It were analyzed four different concentrations, for each concentration were conducted seven tests, during sixty days the lime mud remained in rest mixed with the soil acidity, with pH reading been taken every 15 days. Elapsed this period, bean seeds were planted, in order to evaluate the growth and development of each plant in each concentration. These plants grew during thirty days, before being ‘collected’, for being analyzed their characteristics as, biomass gain, size of the main root. Besides these tests, it was performed a characterization of the lime mud, regarding to pH, moisture, PN (Power Neutralization) and PRNT (Relative Power Neutralization Total). Proving that the feasibility of the lime mud as a corrective to acidic conditions, we have a market for this residue (lime mud), may give profits to the company and become a marketable product.
