In biodynamic farming and gardening one can speak only of a substitution of existing mineral deficiencies. This is not a matter of raising the substance level to the level of scientifically recommended guideline values — for the gradual liming aimed at restoring an acid-base equilibrium, pH > 6 can serve as such a guideline — but rather of stimulating, with the help of rock dusts, the "sense activity" of the root referred to above, in connection with the associated soil life. This twofold peripheral metabolic and root sense-activity directs the breakdown of the rock dust and through it the stalled biogenic breakdown of the mineral reserves of the soil. In this regard the silicate primordial rock dusts are of particular significance. They contain the full spectrum of all those substance-elements which form the starting-point of the development of the most fertile soils. In the purely mechanical grinding process, the strictly geometrical substance-composition of the silicates is preserved. The weathering of the fine particles occurs in the aerated, humus-rich, metabolically active topsoil and is therefore a largely biogenic process. It leads to the genesis of primary and secondary clay minerals in the fine-root zone of the *rhizosphere*. In addition, chemical and light etheric forces are released — forces which in primordial times had congealed in the passage from the condition of the living-watery into the dead form-state of the earthy-solid.
