  In the framework of the effective field theory approach to heavy
supersymmetry radiative corrections in the Higgs sector of the Minimal
Supersymmetric Standard Model (MSSM) for the effective potential decomposition
up to the dimension-six operators are calculated. Symbolic expressions for the
threshold corrections induced by $F$- and $D$- soft supersymmetry breaking
terms are derived and the Higgs boson mass spectrum respecting the condition
$m_h=$125 GeV for the lightest $CP$-even scalar is evaluated.
