Investigation of batiotic parameters in-situ of cultivated grassland, using physical measuring methods

Abstract

In order to understanding a fluctuation of the physical processes, it is necessary to analyze a lot of physical parameters: temperature of atmosphere and soil, gas concentration (O2, CO2 and ethylene), soil solidity, dependency of the wind velocity on the height and density of plants, humidity of the soil, plant albedo variation dependency on the surface topography, vegetation period and other factors. Our experiments have been done using data collection according to the national USDA‘s Forest Health Monitoring Program [1]. 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. The all dependency of the various physical data was valuated according on the plant growth. All picked data set should be used analyzing ecological drivers on the fluctuation of the climate. Soil structure influenced humidity, which affected traffic ability, compaction and nitrogen retention. 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[2]
