  The Minimal Supersymmetric Extension of the Standard Model (MSSM) is able to
explain the current data from neutrino physics. Unfortunately Split
Supersymmetry as low energy approximation of this theory fails to generate a
solar square mass difference, including after the addition of bilinear R-Parity
Violation. In this work, it is shown how one can derive an effective low energy
theory from the MSSM in the spirit of Split Supersymmetry, which has the
potential of explaining the neutrino phenomenology. This is achieved by going
beyond leading order in the process of integrating out heavy scalars from the
original theory, which results in non-renormalizable operators in the effective
low energy theory. It is found that in particular a $d=8$ operator is crucial
for the generation of the neutrino mass differences.
