  We apply the background field technique, recently developed for a general
class of nonlinear symmetries, at tree level, to the Volkov-Akulov theory with
spontaneously broken N=1 supersymmetry. We find that the background field
expansion in terms of the free fields to the lowest order reproduces the
nonlinear supersymmetry transformation rules. The double soft limit of the
background field is, in agreement with the new general identities, defined by
the algebra of the nonlinear symmetries.
