Résumé
A clay soil (Typic Humaquept) was incubated with various amounts of calcium lignosulphonate (CaLS), a waste product from the pulp and paper industry, and potassium dihydrogen phosphate. Subsamples were extracted with deionized water and the Mehlich-III solution for the analyses of pH, and P, Ca, K and Mg concentrations and K adsorption. High temperature reduced extractable K; and CaLS and K additions increased extractable Mg. Additions of CaLS increased extractable K, but adsorption decreased with the increases in CaLS addition rates. Significant positive linear relationships were observed between K adsorption and the concentration ratio [K+]/[Ca2+]1/2, suggesting that the potassium buffering capacity of the soil was reduced by the additions of CaLS, with the desugared CaLS being more effective than the non-desugared CaLS. The results indicated that CaLS improved the quantity and intensity relationships and increased the power of the soil supplying plants with K. -from Authors
