Import good black soil from some where else,mix it with alot
of salt and charcoal dust, dig atleast 2 pits in a space of
10metres apart.
Let each pit have its own earth mat and burry it wit the
mixture mentioned above ie salt, black soil and charcoal
dust and then bond or interconnect the earth mats wit an
earthwire of ATLEAST 35mm2.
Finally pour alot of water in the pits.
