Looking at this question from the chemistry point of view,
l can confidently say:
(i) Coal in form of graphate, is a good conductor of
electricity due to a free electron wondering around it's
bonds, hence the resitance of earth reduces due to the
presents of coal.
(ii) Salt in solution for does ionise to Na+ and Cl-
ions. These ions are good conductors of electricity, hence
the earth resistance does reduces when salt is present on
earth.
(iii) Water does partially ionise to give H3O+ and OH- ions
which conduct electricity. This also reduces the earth's
resistance.
