The applications of organic modifications are alternatives used for the physical, chemical and biological improvement of soil. A good example is mature or fresh sugar cane sludge, a by-product of the traditional or semi-industrial process of the sugarcane-producing region called “Hoya del Río Suárez (Chitaraque, Boyacá)”. In this research, the behavior of the interchangeable bases Calcium (Ca+2), Magnesium (Mg+2) and Potassium (K+) in the colloidal fraction of the soil was determined from a DCA type design with six treatments (T0: Control only with calcareous modification (6.6 t ha-1 Dolomite). T1: Commercially (0.44 t ha-1 of 15-15-15) + Dolomite. T2: mature sugar cane sludge (5.7 t ha-1). T3: Abimgra (3,3 t ha-1). T4: 75% mature sugarcane sludge + Abimgra (2.85 t ha-1 plus 1.65 t ha-1). T5: 50% sugarcane sludge + 50% Abimgra (2.85 t ha-1 plus 1.65 t ha-1). T6: 25% mature sugarcane sludge + 75% Abimgra (1.42t ha-1 plus 2.47 t ha-1) and four replications where the concentrations of the bases were determined before sowing and in the crop of the Cerinza ICA variety bean. Concluding that the application of 2.85 t ha-1 of sugar cane sludge and 1.65 t ha-1 of Abimbra, obtained the best results in the increase of Ca+2 and Mg+2 bases, reaching values of 7 cmol(+) kg-1 of soil and 1.8 cmol(+) kg-1 of soil respectively. The above stated explains the great potential of mature sugar cane sludge with the contribution of calcium and magnesium.
