COMBATT-CABALLERO, Enrique; NOVOA-YANEZ, Rafael  e  BARRERA-VIOLETH, José Luis. Chemical characterization of macroelements in soils cultivated with Harton plantain (Musa AAB Simmonds) in the department of Córdoba, Colombia. Acta Agron. [online]. 2012, vol.61, n.2, pp.166-176. ISSN 0120-2812.

Fertilizer recommendations for hartón plantain cropping should be done by interpreting the chemical characteristics of soils to be reliable from the technical point of view and principally based in technical adjustments in relation to the nutritional potential of soils. The aim of this study was to evaluate the chemical characteristics of macroelements in soil in 40 farms cultivated with hartón plantain in the department of Córdoba, Colombia. The parameters measured were: pH, organic matter (O.M.), P, S, Ca, Mg, Na, K, according to the analytical procedures proposed by Geographic Institute Agustín Codaz (IGAC). Analysis of variance and mean comparison tests (Tukey) to the data were performed. The analytical results showed that the soils had a moderately acidic reaction, with pH lower than 6 on the High Sinú zone and slightly alkaline with pH 6.5 in the coastal zone. The organic matter content was less than 2.1%, P between 16.4 and 35.3 mg kg^-1 and S deficient with values less than 13.5 mg kg^{-1 in all municipalities. Values of Ca, Mg and K were high, but with a tendency of antagonism of the ion Ca with respect to K.}
