Abstract

In this research, kinetics of phosphorus (P) extraction by sodium bicarbonate from the ≤ 2 mm fraction of 12 calcareous soils of East Azerbaijan province was investigated using surface (0-30 cm) soil samples. Soils were equilibrated with 0.5 M, NaHCO3 solution for 0.25 to 16 h. To determine the corn plant growth parameters a factorial experiment in a randomized complete block design with three replications was conducted for a period of 2 months. According to the results, the minimum and maximum amount of extracted P during 16 hours was 5.54 and 38.15 with a mean of 15.68 mg P.kg-1, respectively. Comparisons of coefficients of determination (r2) and standard errors (SE) for seven different models indicated that the best models for describing the P release data in all soils were two-constant rate, parabolic-diffusion and simple Elovich equations, respectively. The zero, first, second- and third order equations could not describe P release properly and r2 decreased from zero to third order. Soil organic matter was the most pertinent soil characteristics that predicted the rate constants of the two constant and parabolic kinetics models. The parameter (a) of two-parameter rate equation, was positively correlated with shoot dry weight of corn and shoot P content (r=0.75** and r=0.61**, respectively).There was no significant relationship between rate parameter b and measured corn plant parameters either singly or in combination. Although, the amount of the extractable P for initial extraction time (a.b constant) was significant and positively correlated with shoot dry weight (r=0.76**). The diffusion rate (kp) of parabolic-diffusion equation showed significant relationships (p<0.01) with dry matter of corn shoot. Consequently, a soil test for available P (Olsen-P) that involved extraction for a quite short time period might underestimate the amount of P that is eventually released to soil solution and plants.
