  Solid ammonia (NH$_3$) is commonly used as a dynamically polarized proton
target for electron and muon scattering cross-section asymmetry measurements.
As spin 1$^{+}$ particles, the $^{14}$N nuclei in the target are also polarized
and contribute a non-trivial asymmetry background that should be addressed. We
describe here a method to extract the nitrogen contribution to the asymmetry,
and report the cross-section asymmetries of electron-nitrogen scattering at
beam energies of $E=1.7$ GeV and $E=2.2$ GeV, and momentum transfer of
$Q^{2}=0.023-0.080$ GeV$^{2}$.
