The assessment of multiple physical parameters (temperature and humidity of atmosphere and soil, gas concentration, soil solidity, wind velocity, greenhouse gas emissions) is necessary to improve knowledge about management of agro ecosystems. The approach is based on the local measurement and comparing the impact of environment physical indices on agro ecosystems productivity at crop habitat scale. The study was conducted in semi natural grassland (54o52′ N, 23o50′ E) at Training Farm of Lithuanian University of Agriculture in 2009 and in intensive grassland at conventional farm (Kalvarija distr., 54o28′ N, 23o38′ E) in 2011 respectively. 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 picked 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.
