Maize for acid soils. First scientific report - 2001 : INCO2 contract No ICA4-CT-2000-30017
The objectives for the first year of the work package 10 were to write and calibrate a model of Al and P dynamics in the rhizosphere. The Rhizodyn model, developed within the preceding European program "Fitting maize for acid soil", was supplemented (i) for its use on Windows 2000/NT environment, (ii) with a module of adsorption for the anions (phosphate and organic anions), and (iii) with a thermodynamic data base including the constants of formation of the complexes between anions and Al and Fe. In parallel, the model was calibrated for the P adsorption in using isothermal and kinetic studies highlighting the effect of the pH on the fixing of P. An experimental study was done with a soil of Colombia using a special culture device, making possible to conveniently analyse the rhizosphere soil. This work allowed a detailed study of the interactions between H, Al and P in the rhizosphere. It will allow later the validation of the model and the study of sensitivity of the parameters.
