ANALYSE PAR DILUTION ISOTOPIQUE DE LA FERTILITE ET DE LA FERTILISATION PHOSPHORIQUE DE QUELQUES SOLS DU QUEBEC

Analysis of available soil phosphate by isotopic dilution method, observed as kinetics between 1 and 100 min after the injection of 32 PO 4 3− in the soil–solution system, allows the measure of three kinetics parameters: r 1 /R, r 1 is the radioactivity remaining in the solution after 1 min of isoto...

description Analysis of available soil phosphate by isotopic dilution method, observed as kinetics between 1 and 100 min after the injection of 32 PO 4 3− in the soil–solution system, allows the measure of three kinetics parameters: r 1 /R, r 1 is the radioactivity remaining in the solution after 1 min of isotopic exchange and R the total radioactivity injected in the system, n the slope of the straight line which, in logarithmic coordinates, gives the decrease of the radioactivity remaining in the solution versus time, and p the phosphate-ions concentration in the solution. Analysis performed in this manner on some Canadian typical agricultural soils shows that localization of phosphatic fertilizers is absolutely necessary in some cases, the soil fixation capacity for phosphate ions being too large. In these soils a homogeneous increase of available soil phosphate is economically impossible.
