Solubility relationship of sulphur (S) and phosphorus (P) were evaluated in two calcareous soils. Balkasar (Udic Haplustall) and Shahdara (Typic Torrifluvcnt) soils amended with 0,25, 50 and 75 mg/k~~ each of Sand P in all possible combination in triplicate according to completely randomized design were incubated at 25 ± 2 0 C. After four weeks of incubation period the amended soils were extracted with CaCI2 and NaHC03 for Sand P estimation. Application of Sand P had a significant (P <0.01) main and interactive affect on CaCI2 as well as NaHC03 extractable Sand P in the two soils. Influence of P application was more prominent than S on their extractable quantities in the two soils. Significant (P < OJl1) relationship between NaHC03-S(Y) and applied S(Xl) and P(X2) was Y = 14.85 + O.5Xl + 0.8X2 (R = 0.(7) in Balkasar soil and was Y = 15.95 + 0.53X 1 + 0.073X2 (R = 0.(8) in Shahdara soil. Singificant (P < 0.05) relationship (R = 0.70) between NaIICC):j-S(Y) and CaCI2- SeX) was given by the equation: Y = - 5.7<)+ 2.11X. Significant relationship between NaHC03-P(Y) and applied P(Xl) and S(X2) was Y=O.17 + 0.97Xl + O.17X2 (R=0.98) in Balkasar soil and was Y=OJi7 + 0.93Xl + OJl4X2 (R=0.98) in Shahdara soil. Applied P mainly precipitated as Ca-phosphates in the two soils. Significant (P
