To achieve optimum yields in plantain production, appropriate fertilization plans must be adjusted, for which the availability of nutrients in the soil must be taken into account. In order to contribute to the study of the fertility of soils cultivated with cooking banana in the province of Cundinamarca - Colombia, a chemical characterization of soils was carried out in four of the main producing municipalities. 146 farms located in Viotá, La Vega, La Palma and Chaguaní, were visited, and soil samples were taken for chemical analysis. The results obtained were subjected to a frequency analysis, Pearson’s linear correlation and main components; fi nally making a comparison of means between the four municipalities. Low levels of P, S and Mg, medium of K, Ca and B were observed, as well as high concentrations of Zn that can be toxic for the plantain crop. On the other hand, the variables were grouped into four components associated with: the soil change layer, the soil reaction, the salinity and the relationship between P and Zn. Soils of the municipalities of La Vega and La Palma did not show variation in the change layer and soil reaction, contrary to that observed in Viotá and Chaguaní soils. Among the soils of the municipalities, there were significant differences for the properties of organic matter, Ca and Mg as well as cationic imbalances and strongly acidic pH.

Filter cake can be used in agriculture as soil corrective or fertilizer, but its potential is unexplored until now. This research, carried out at Chitaraque/Boyacá, aimed to evaluate the effect of different doses of soil corrective (fresh filter cake), compared with a commercial fertilizer and maize without treatments. Each experimental unit (EU) was composed of 96 plants for a total of 2,304 for the experiment. The physiological variables analyzed were measured at harvest time, selecting eight plants of the center of each EU, and were: kernel number per cob, weight of 100 kernels, plant height (cm), stalk diameter at 50 and 100cm of plant height, leaf area (cm2), fresh matter (g) and dry matter (g). The higher kernel production was obtained with the application 7.5t.ha-1 of fresh filter cake. The doses of 5.8t.ha-1 resulted in the highest production of dry kernels and the greatest height was founded with 15t.ha-1 of fresh filter cake; the same dosage originated the thickest diameter. The greatest amount of foliage and fresh matter were found with 12.5t.ha-1. Dry matter, on the other hand, didn’t show statistically significant differences between the various doses of fresh filter cake. The use of fresh filter cake showed higher fresh mass and the dose of 8t.ha-1increased the kernel number, since the application of this organic amendment helped to improve corn yield and can supply, in this case, the chemical fertilization.
