Abstract: In order to understand a fluctuation of the physical processes in agro environment, it is necessary to analyze a lot of physical parameters: temperature of atmosphere and soil, gas concentration (O2, CO2 etc.), soil solidity, dependency of the wind velocity on the height and density of plants, humidity of the soil, vegetation period and other factors. Our experiments have been done using data collection according to the national USDA‘s Forest Health Monitoring Program (Stohlgren, 2007). Cultivated grassland as the target of the investigation has been taken. The data have been collected in a real time using digital sensors of the humidity, pressure, gas concentration, solar intensity, wind speed and temperature. All the dependencies of the various physical data were valuated according to the plant growth. Data were obtained in cultural grasslands with different fertilizer application and in crop fields of different geographical location. The experimental data confirm that the average meteorological data obtained from the State Meteorology Stations are quite preliminary and cannot be unambiguously considered as the environmental factors on the wide area of vegetation with different soil. The gathered data set should be used when analyzing ecological drivers on the fluctuation of the climate. Measurement of properties that affect fluid storage and transport, such as macro porosity, provided soil quality indices that helped in recommending suitable soil management systems (Harpal et al., 2004)
