Soil health and freshwater are linked closely, and are the keys to environmental safety. Conflict of biosphere and current technology violates both soil and freshwater. This conflict to a great extent is due to current outdated irrigation consuming 95 % freshwater global resources, irrigation water losses are 4–15 times higher than the empirically determined irrigation water need of plants.<br/>Current irrigation paradigm is based on imitation of natural rain, drip, surface or subsurface water flux to soil and therefore, as it is in nature, links together two stages of the soil moisturizing process – water supply, and water spreading throughout soil aggregates system. This systemic disadvantage of standard irrigation simultaneously reproduces other properties of natural hydrological process – soil moisture and vegetation spatial differentiation, soil over-moistening and landscape waterlogging, preferential water fluxes through the soil to vadose zone and saturation zone, uncontrolled biogeochemical process.<br/>We propose transcendental (non-imitating the nature directly) Biogeosystem Technique (BGT*) multifaceted methodology which provides non-conflicting sustainable technological development and environment safety. Intra-soil pulsed continuously-discrete watering paradigm is a BGT* technological capability for the new world water strategy creation. Intra-soil pulsed continuously-discrete watering is executed by syringe successive small water portion injection into soil vertical cylinder of 1.5–2.5 cm diameter at depth from 10 to 35 cm. In 5–10 min after injection the soil water redistributes in the vicinity of cylinder via capillary, film and vapor transfer. An ambient soil carcass is dry and mechanically stable. This provides aggregation of hydrodynamically disturbed zones of soil. Resulting matrix soil water potential is of −0.2 MPa. Soil solution concentration is optimal for plant nutrition and healthy for soil biota. Stomatal apparatus of plants operates in regulation mode providing saving water. The soil health and plants biological productivity are high. Fresh water consumption is 4–20 times less compared to standard irrigation. Fertilizers and pesticide efficiency is high, their loss and damage to environment are low. Robotic intra-soil pulse continuously-discrete irrigation technology is available. BGT* gives an opportunity to overcome the global water scarcity, to expand the area of productive and healthy biosphere, and stabilize the climate.
