Abstract

It is argued the cosmogeobiotic nature of the pedosphere (or of soil cover), and the absolutely necessary involvement of the substance and energy fluwes in the formation and existence of soil, new aspects that make complet knowledge in this field. The soil is cosmic due to solar main source of the energy involved in soil genesis and due to cyclic development of this process. It is telluric (geo) due to geological origin of the mineral components of soil and their movement on Earth’s surface under influence of the gravity. It is biotic due to intimate implication of the biota in soil formation and dynamics. Four fluxes of substances and energy are indispensable for soil existence: water, air, nutrients and energy fluxes. The energy flux, unlike the other fluxes, is not cyclic, but one-directional, the solar energy being permanently renewed. A new scenary of soil formation and development is presented. In this new synergic scenary of pedogenesis the above mentioned fluxes of substances and energy (information included) are involved in the soil genesis, developing the present factorial concept of the pedogenetic processes and factors in soil genesis. The soil is a fundamental natural and indispensable resource of the Earth because it fulfils very important functions by which is involved in the most essential features of the environment and life, as hydrological cycle, nutrients cycle, surface sediment circulation, global climate, environment stability, creatures health. All these show not only the complexity of the pedosphere, but also the planetary importance of the pedosphere because any perturbance in the soil cover will affect seriously biosphere, the environment and implicitly the society with unforeseeable consequences.
