HC Vegetation


Despite being on an artificial surface, the HC’s will have a thriving natural and vegetative environment complete with various grass lawns, trees, bushes, hedges, flowers, etc.

HC Soil
The HC’s vegetation will be planted in normal environment of soil. On average the thickness of the soil will be about cm ( in) and will cover a total area of hectares ( acres). The volumetric total of the soil is calculated to be about million m3 ( billion ft3). The following table shows the projected soil distribution throughout an HC.

Holy CIty Soils-

Soil Provenance
NJK Mission Campuses Lands
The source of this can come from three potential places. The first of these sources would come from the lands that will be purchased by the NJK for the location of its Mission Campuses. From these campuses, averaging about hectares ( acres) each, the excavated soil from the foundations/basement space of the campus’ buildings would be transferred to the Holy Cities. If these buildings on the campuses take up about of the total campus area then the total foundations/basements of each of these building would be about m ( ft) deep.

Original Sources
The HC’s soil can also be composed from scratch by combining the various elements needed to make healthy soil, namely: sand, clay, silt, nutrients/organic material, air and water. These materials can easily be obtained from the abundant sediments of the ocean floor which are in most areas kilometers/miles thick and from seawater.


The following tables show the expected volumes and weights for each of these elements that would be needed to make a medium loam (see composition table here) for 1 and for HC soil needs.

Commercial Sources
A third potential source would be to purchase soil from countries willing to sell it. If a probable price of USD per metric ton is used the total cost for the HC’s would be about (USD) or per capita. This works out to per hectare ( per acre). This soil would not have to be of top soil quality as it could be enriched later on, at the HC’s using the abundant nutrients found in ocean waters.
