Abstract

Determination of forms of soil phosphorus (P) is important in the evaluation of soil P status. Amount and distributions of soil organic and inorganic P fractions were examind in 53 soil samples of Hamedan province. Soils were sequentially extracted to determine organic and inorganic P fractions. Inorganic P was divided in to 6 fractions: Dicalcium phosphate (Ca2-P), Octacalcium phosphate (Ca8-P), Apatit (Ca10-P), P absorbed by Al oxides (Al-P), P absorbed by Fe oxides (Fe-P) and Occluded P ( O-P). The results showed that wide range in content of P fraction. The amount of total P (TP) ranged from 926 to 2686 mg kg-1 with an average of 1533 mg kg-1 soil. Calcium phosphate (Ca2-P + Ca8-P + Ca10-P) ranged from 104 to 1872 mg kg-1 with an average of 801 mg kg-1 soil and being comprised of 78.5 and 52.3% inorganic and total P respectively. The amount of Fe-P ranged from 1 to 185 mg kg-1 with an average of 59  mg kg-1 soil and being comprised of 5.8 and 3.8% inorganic and total P respectively. The amount of Al-P ranged from 4.6 to 523 mg kg-1 with an average of 128 mg kg-1 soil and being comprised of 12.5 and 8.3% inorganic and total P respectively. The amount of O-P ranged from 0.0 to 371 mg kg-1 with an average of 33 mg kg-1 soil and being comprised of 3.2 and 2.2% inorganic and total P respectively. The amount of organic P ranged from 75 to 676 mg kg-1 with an average of 277 mg kg-1 soil and being comprised of 18.1% total P. The results of correlation study showed that available P (P extracted by Olsen method) was significantly correlated with Ca2-P, Ca8-P, Al-P, Calcium phosphate  (Ca2-P + Ca8-P + Ca10-P) and (Aluminum, Iron oxide: Al-Fe-P), This result indicate that these fractions probably can be used by plant.
