This study was conducted to determine the relationships among the routine soil tests such as Ammonium Acetate, Olsen, and DTPA-TEA and two multi-element soil tests (Mehlich-III and AB-DTPA). The comparison of the routine tests with Mehlich-III gave high correlations for plant available K, Zn, and Cu, moderate for P andMg, low for Fe, and no correlations for Ca and Mn. The routine soil tests and AB-DTPA test, on the other hand, gave high correlations for plant available K, Zn, Cu, and Mn, and moderate ones for P, Mg, and Fe. The two multi-element soil tests showed high correlations with plant available K and Cu, moderate one for P and Mg, low with Zn, and no correlations with Ca, Fe and Mn
