A method for computing the low-energy non-perturbative properties of SUSYGFT, starting from the microscopic lagrangian model, is presented. The methodrelies on covariant SUSY Feynman graph techniques, adapted to low energy, andRenormalization-Group-improved perturbation theory. We apply the method tocalculate the glueball superpotential in N=1 SU(2) SYM and obtain a potentialof the Veneziano-Yankielowicz type.Comment: 19 pages, no figures; added references; note added at the end of the paper; version to appear in JHE
