The fluid description of neoclassical transport theory is applied to a general nonaxisymmetric toroidal multispecies plasma with sources. From moment equations, expressions for plasma rotation, electric current, radial heat and particle transport fluxes, and ambipolar electric field are obtained. These expressions are valid in both the plateau and collision-dominated regimes. The effect of momentum and energy flux sources on particle and heat flows, electric current, radial transport fluxes, and on the ambipolar electric field is explicitly shown. In these calculations radial temperature gradients are taken into account.
