  A nonlinearly realized supersymmetric action describing the invariant
couplings of the Goldstino to matter is constructed. Using the Akulov-Volkov
Lagrangian, any operator can be made part of a supersymmetric invariant action.
Of particular interest are interaction terms which include the product of the
Akulov-Volkov Lagrangian with the ordinary matter Lagrangian as well as the
coupling of the product of the covariant derivative of the Goldstino field to
the matter supersymmetry current. The later is the lowest dimensional operator
linear in the Goldstino field. A Goldstino Goldberger-Treiman relation is
established and shown to be satisfied by the effective action.
