Retención de fósforo en suelos canarios en función del tiempo y concentación. III. A tiempo de 24 horas
That is a study related to the determination of maximum P adsorption and bindinging constant between P and some soils of Tenerife and Gran Canaria Islands. The shaking is 24 hours, after that P and pH are determined in soil extracts. These parameters are evaluated by the Shapiro-Fried, maximum P adsorption values obtained are: (360-1300), (1075-2400), 2300-3000 ppm) for salinized soils, alfisol, oxisols and andosol respectively. The correlation coefficients between this parameter and Al, Al + Fe soluble forms in oxalate are significant at 2 and 5% levels. It seems that in the oxisol of Poleo a secondary fixation was produced during this shaking time of 24 hours.
