THE EIS METHOD CAN IDENTIFY CHANGES IN WATER CONTENT IN SOIL PORES: DETECTION OF DRY AND WET SOIL BY EIS METHOD IN THE CHERRY ORCHARD IN ŽABČICE, CZECH REPUBLIC

Abstract

Climate change is a complex and to some extent defining problem of our time, including the issue of their monitoring. From shifting weather patterns that threaten food production, to rising sea levels that increase the risk of catastrophic flooding, the impacts of climate change are global in scope and unprecedented in scale. The each other interconnected processes of mass and energy transfer are well visible in an integrated dynamic system called the hydrosphere. The hydrosphere is the combined mass of water found on, under, and above the surface of the Earth. Meteorological conditions undoubtedly have, in addition to different agro-ecological conditions, a significant influence on the monitored yields and crop quality. The paper presents the results of the soil monitoring at cherry orchard Žabčice, Czech Republic in place with different species of grassland with different lengths of their roots. Monitoring was realized manually with frequency one per month with using Z-meter devices developed through international EUREKA programme. The monitoring system allows measurement at one selected frequency of the measuring signal, or measurement in a frequency band. Both approaches were used to monitor changes in soil water content. Changes in the water content in the soil were monitored during artificial irrigation of grass (frequency spectrum) with a mobile probe and due to changes in the weather - drought and after torrential rain on the site (chosen frequency of the measuring signal) with stable probes. For practical reasons to limit the influence of uncertainties, the measurement was conceived as relative, and therefore calibration was not carried out for e.g. relative humidity of the soil. The monitoring results show the possibility of using the measuring system for the given purpose in full, including the possibility of its automation.
