PERFORATED TUBES TECHNIQUE FOR WATER AND NUTRIENTS' FERTIGATION: A NEW TECHNOQUE BASED ON SUNSHGINE MODEL

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, the antenna, receives the incoming electromagnetic radiation from star sun, executes the code of optimality to let the life on planet earth continue under the stressed conditions. In additions, it does the good for the best to 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 relationships between the 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 morning. A hidden type of relativity organizes these eco-communications in order to mitigate limited levels of abiotic relative climatic extremes. This leads the lives in the agro ecosystem toward the survival under suboptimals'. An application to the SUNSHINE theory is PTFT for water and nutrients' fertigation. It depends on passing the groundwater through a network of palm fiber or rice straw prior to its infiltration. The water distributer in the invented technique is made up by silicon. The silico-fiber network leads the geo-biophere toward the optimality. It could Enhance the role of Pangaea's by making a wide eco-communication between the underground root zone (as the geosphere), the underground root system and its exodates (as a biosphere), the underground aquifer (as a cooling medium under temp. rise), as well as the above ground canopys' each sunshine).
