In this work, we have studied the invariants of motion of two SU(N)supersymmetric t-J model of $1/r^2$ hopping and exchange in one dimension. Thefirst model is defined on a lattice of equal spaced sites, and the second on anon-equal spacing lattice. Using the ``exchange operator formalism'', we areable to construct all the invariants for the models, by mapping the systems tomixtures of fermions and bosons. This identification shows that thesupersymmetric t-J model on the chain with equal-spaced sites also belongs toShastry-Sutherland's ``Super-Lax-Pair'' family.
