The burning with dark fume is good test but not advised by green chemistry. But you could do primary test using wetting behavior. In other words, most inorganic salts adsorbs water molecules (hydrophilic) in contrast with organic materials which mostly hydrophobic. You could also use this same idea through using the drying ability behavior. Organic materials get dry from water easily in contrast with inorganic using sensitive balance.

organic compost is not water soulble . in organic compost materials mostly water soulble. or else inorganic compost go for salt analysis for any salts.
