To make an artificial chernozem topsoil combine approximately fifty percent dredged river silt and fifty percent cellulose from recycled paper with ten percent composted animal or human waste for general reclamation and cereal crops, or vegetable or fruit residuals for gardens or potting soil, and then add five percent calcium in the form of calcium silicate as slag or lime and .1 percent ammonia nitrate or sulfate mixed with water, and then add charcoal until the moisture turns black. This combination of material replicates the calcium base, decaying cellulose, silt and animal or vegetable waste structure of natural chernozem. Magnesium, sodium, potassium, and phosphorus, the peculiar trace elements of a chernozem are contained in waste residuals and silt. Other soil types can be duplicated by adjusting the base content to sand or basalt and rearranging the nutrient and mineral content to match the local sail profile, and then adding seeds appropriate to yield the area's naturally occurring foliage. The above mentioned elements may be combined on a conveyor system at a factory located near major rivets or silt deposits or volcanic sites. The artificial soil can then be barged or trucked back to restore dead fields and eroded hillsides helping to prevent deforestoration and desetertification. Artificial soils of different types would be useful as potting soil, in greenhouses, gardens and in creating artificial environments in space.
