Evaluating forms of phosphorus found in soils planted to plantain
The extractive phosphorus represent a small fraction to the present in the soil and it is found in a dynamic balance with organic and inorganic forms. Was carried out in two zones dedicated to the plantains plantations in the municipality of Moñitos (Cordoba, Colombia) in where were took sampling of soil and the foliage tissue (The leaves of the plantains plants) through a stratified sampling at random. Was determined the differents forms of the phosphorus: P-Easily, P-Ca no apatitico, P-Al, PFe, P-Ca apatitico, for fractionation method proposed by ( Chang and Jackson, 1957), it was modified by (Petersen and Corey, 1996; Willians et al., 1967). Showed that in both soil units CM-CA and PM the major contribution to inorganic phosphorus of the soil from P-Fe the P-Ca apatitico and the PCa no apatitico, while that the P-easily replace and the P-Al was low percentage for these kind of soil types. the process of fractionation of the inorganic phosphorus from the soil extracted level of organic forms, and it is evidence of the level obtained to the phosphorus of the soil and the total inorganic phosphorous as a result of the fractionation.
