A SCENARIO OF THE SYNERGIC INTERACTION OF FLUXES, PROCESSES AND CONDITIONS (FACTORS) OF SOIL GENESIS

Nicolae Florea

Abstract


The soil, respectively the pedosphere, is the result of the interactions not only of the pedogenetic factors and processes, but also of the fluxes of substances, energy and information, which unroll cyclically in close interdependence with environment conditions (these ones include also the force fields: electromagnetic, of gravity, radiant energy, etc.). The initial mineral fund originates from parent material, and the organic fund especially from annual input of organic matter produced by vegetal cover photosynthesis.
The well known triad of pedogenetic factors – pedogenetic processes – soil is developed in the new model of the triangle of synergic interaction of the fluxes, processes and factors of soil formation and evolution, presented in the annexed figure. The soil (pedosphere) makes the connection between the cosmos (solar radiations) and the four geospheres of the Earth.
The soil is a very complex natural body or, more correctly said, a natural system, containing life which is formed over a long period of time (on a geological scale). Therefore, on the scale of human life, the processes involved in the soil-forming cannot be investigated (with few exceptions). Consequently, considerations on soil genesis are based on observations obtained in territories for areas with different ages, sediments, rocks and bioclimatic conditions and their interpretation (having in view the geological principle of actualism, partially contested by some specialists). Of course, these circumstances have favored many discussions which in time have led to the improvement of the soil-genesis description model.
