The uncontrolled water, mineral and organic matter transfer is an adverse consequence of the standard ecosystem’s management. The amelioration and remediation Biogeosystem Technique (BGT*) was developed based on transcendental technology (not copying natural phenomena directly) for intra-soil milling and simultaneous application of the waste, amendments, fertilizers, and biological stimulants. The technology-focused on the C biological phase enrichment, and controlled turnover of N, P, and microelements including HMs. The mobility, transfer, and bioavailability of C and HMs in the soil affected by calcium carbonate equilibrium (CCE) in soil solution. In its turn, the CCE depends on the ionic strength and ion activity of the soil solution. CCE determines the formation of associated ions, mineral and organic complexes. The ion association cause excess saturation of the soil solution with calcium carbonate. This leads to excessive SOM and HMs mobility and transfer from the chain of discrete soil solution micro-basins between soil aggregates to the vadose zone. The organic matter lost from the active soil-biological process. The HMs spread throughout the environment. The mathematical model ION–3 was developed to calculate free and associated ion forms in the soil solution (or water extract) considering CCE, ionic strength, and ion pairs CaCO₃⁰; CaSO₄⁰, MgCO₃⁰, MgSO₄⁰, CaHCO₃⁺, MgHCO₃⁺, NaCO₃⁻, NaSO₄⁻, CaOH⁺, MgOH⁺, PbOH⁺, Pb(OH)₂⁰, PbCO₃⁰, Pb(CO₃)₂²⁻, PbHCO₃⁺, CdCO₃⁰, CdHCO₃⁺ and CdOH⁺. The Biogeosystem Technique (BGT*) provides a higher level of the CCE certainty, soil organic matter and HMs. The intra-soil milling of the 20–50 cm layer ensures soil aggregate multilevel architecture and well developed “soil–water–rhizosphere” interfaces. Intra-soil pulse continuous-discrete watering provides soil solution matrix potential from −0.2 MPa to −0.4 MPa. Both components of technology reduce C mobility, passivation of the HMs due to rather low soil moisture and allow environmentally safe intra-soil waste recycling and amendments, fertilizers, and biological stimulants application. The technology is helpful for the controlled biogeochemical cycling of C, N, P, and microelements including HMs. BGT* transcendental methodology improves biogeochemical cycling, provides higher soil productivity and biological resources growth.
