The invention relates to the description of an installation for the
experimental study of the dynamics of soils degradation
processes, which can be used for the estimation of spatialtemporal
evolution of soils degradation processes, and of the
impact of salinisation, campactation or pedogeochemical
segregation processes in soils from protected spaces (glasshouses
and solariums). The main component of the installation is a
micro-reactor, with a total volume of 1250 cm 3 and an optimum
work volume of 800 cm 3 . The solid phases (soil samples) are
placed on a support consisting of a set of three sieves, made of
Teflon and stainless steel. For heating of the micro-reactor, can
be attached an electrical heating jacket provided with
temperature regulator. The monitoring of pH, redox potential and
ionic species concentration in soil sample is done using adequate
electrochemical sensors. The installation has a special device for
collection of solution samples from micro-reactor (for detailed
physic-chemical analysis) and the control of work atmosphere
