In regard to created a synthetic soil...any brown field or area that has been depleted of nutrients because of the use of chemical fertilizers, pesticides and herbicides can be greatly improved and eventually become fertile soils by adding humus to the system. Humus is derived from composting with a hot compost practice. It is the product that is partially decomposed material. Added to the soil is breaks down further to humic acid and fulvic acid that act as detoxifying agents and chelates to change the charge on cations and act as a delivery system to the vascular pathways of a plant. Why try to create something that already exists and can function in stressful situations. All we need to do is introduce humus to a damaged system.
