The issue of fast-growing crops originally goes back to early 1970th. Fast-growing crops initially dominated as a way of obtaining the raw material for producing cellulose. In subsequent years, with the development of technology, the range of benefits of this type crops began to increase - for example crops found use in the purification of industrial pressure land (reclamation of degraded areas e.g. coal mining) or were used in the production of biofuels (bioethanol, biogas, biomass). With the increasing interest in fast-growing crops, scientific research has been initiated to assess the impact of such crops on the natural environment. One way to analyze the impact of crops on the environment is to measure the emitted or absorbed carbon dioxide and water vapor. Measuring systems consisting of advanced wind sensors, CO 2 and H2O gas analyzers, temperature sensors (air, soil), radiation sensors (shortwave and longwave), rain gauges, snow sensors and soil heat sensors are used for this purpose. All these devices are installed in systems to determine the mass and energy change in the studied area. The eddy covariance method (EC) technique involving the high frequency measurement the vertical velocity component and the scalar (temperature, water vapor and CO 2 mixing ratios) as used to obtain the fluxes half hourly.
