Reinstatement of Agricultural Subsoils
After pulverisation the elevated pH levels will naturally decline over
time when the soils are exposed to soil moisture and oxygen
causing the process of carbonisation to begin. Leaving these re-
pulverised materials exposed to the elements in their granular form
and periodically turning and wetting them will see a reduction of
the pH to pre-existing levels over the course of 12 to 18 months. If
buried under the topsoil this process may take in excess of two
years to occur.
At PowerCem we believe that to achieve a near full biological
reinstatement over the medium term you need to work hand in
hand with the natural processes within the soils, thereby providing
a more ecological reinstatement process. We promote the addition
of a 100% natural compound, (elemental Sulphur), into the
pulverised granulate layer before mixing in a portion of the parent
topsoil material and wetting the layer. This layer would then be left
exposed to weathering for 3 to 6 months before being mixed again,
pH tested and either continue to be exposed or to have the topsoil
layer reinstated.
