Abstract:
In this paper, the potential aeration conditions of the soils are studied, which are particularly important in establishing
their fertility status necessary for optimal plant development. The indicators that define the air content of the soil,
different forms of porosity are thus analyzed, with emphasis on aeration porosity, pore size distribution, air content at
different suction stages, but also some measured indicators (such as air permeability), which define air movement by
convection (mass flow). Within the current agricultural technological systems, the different ways of working the soil
significantly influence the state of aeration. This process takes place by damaging the soil matrix, by changing the
movement of water in the porous space, by the dynamics of biological processes in the soil or by the combined effect of
these phenomena. In order to obtain the information necessary for the study and research of soil aeration processes, we
approached different methods, namely: direct measurement methods on soil samples collected in experiments with
controlled traffic and in expeditionary studies, as well as indirect assessment methods using the existing information in
the network of monitoring.
