Modeling the Mass Influxes of Water and Nutrients Using Diagnostic Discrete and Continuous Soil Water Energy Modes, DD. SWEM and DC. SWEM

The skeleton of Pangaea is made up by silicon, the second abundant element in the earth’s crust and the seventh most abundant element in the universe. Silicon has a uniqe characteristics which likes the soil water hydraulic capacitance. Accpordingly, Richard’s was used to model the combined mass balanced flow of water and silicates under the abiotic stressed conditions. SF_RE was derived from its basic Darcian-Richard's. It was Darcian- Richard's, modified Richard’s, stress form of Richard’s, then silicon- like soil water hydraulic capacitance of Richard's. HASPs were used for parameterizing the mass flow of water and silicates under the studied abiotic climatic extremes. . Each boundary condition was set according to DSWEM. The author considered that total soil water energy modes are diagnostic because each of which needs a special managerial practice to achieve the target function of better soil tilth. FORTRAN code of DC.SWEM and Thomas' algorithm of DD.SWEM were achieved. As the studied variables, HASP, are newly born from SF_RE. It is recommended to use the statistical modeling to correlate them each to other and to the water and nutrients' stress reduction functions. HASP.α. W_Up and HASP .α. N_Up. The most interesting result is that silicon, the antenna, receives the incoming electromagnetic radiation from star sun, executes the code of optimality to let the life on planet earth continue under stressed coditios. Also, it does the good for the best for all the other agro-ecosystem components. The plants' bio signals, the soils' geo-signals, and the atmospheric canopies’ signals all are under the control of the maternal relationship between star sun solar radiation and the shield of PANGAEA's skeleton, silicon. ISSI_MOD, the conceptual ecohydrological model, has finally led to an eco- geophysical model named as SUNSHINE. The theory of Sunshine supposes that all the silicon atoms are eco-naturally connected forming eco-networks of communications. The latters are the receiver of the optimality signals’ each sunshine. A hidden type of relativity organizes these eco-communications in order to mitigate limited levels of abiotic relative climatic extremes leading the lives in the agro ecosystem toward the survival. An application to the SUNSHINE theory is the replacement of rice straw with clayey factures in the desert air cooler, Pergassy . The latter cause better human health as well as air conditioning than the former.
