Relationship between phosphate adsorption and chemical properties of soil under cocoa
A study on the relationship between phosphate adsorption and chemical properties of soil had been carried out on Typic Fragiudalfs taken from Kaliwining Experimental Station, Jember, East Java. One gram of soil was equilibrated in 10 ml of P solution for two weeks. The concentration of P in the solution was 100 micrograms P/ml. P concentration in the solution was then determined after the equilibration had been reached. Chemical properties of soil such as Al content, Fe content, and pH NaF were also determined. The study concluded that correlation between phosphate adsorption and Al subíndice o, Fe subíndice d, Fe subíndice o, Si subíndice o, and pH NaF were linear with coefficients of correlation 0.78; 0.94; 0.90; 0.77; and 0.85 respectively, while the correlations between phosphate adsorption and Al subíndice d, Al subíndice p, Fe subíndice p, Si subíndice d were not significant. Positive correlation between phosphate adsorption and pH NaF had practical implication since it allowed to estimate phosphate adsorption of soil simply by pH measurement which could be performed rapidly.
