About article:
In recent years the droughts have become more severe as a result of climate change. The ability to monitor drought conditions and assess its risk is essential for an effective drought adaptation plan, especially in agricultural ecosystems. Drought indices allow characterization of drought occurrence and extent. The most widely used is the Standardized Precipitation Index (SPI), which is recommended by the World Meteorological Organization as the standard drought index. Although the main cause of drought is lack of rainfall, recent studies have also pointed out the significant role of air temperature and evapotranspiration. The aim of the work was to determine the monthly values of the meteorological drought indexes of the research site Nitra in the period 2014–2018 and to analyze their sensitivity based on the comparison of the determined droughts frequency. We used indexes: SPI (Standardized Precipitation Index), PNI (Percent of Normal Index), DI (Deciles index), MCZI (Modified CZI) and ZSI (Z-score Index), which take into account the values and distribution of daily precipitation amounts. The secondary aim of the work was to analyze and statistically confirm the relationship between daily EDI (Effective Drought Index) and in daily interval measured moisture content of the top soil of the research site, i.e. to confirm the possibility of using EDI to signal the soil drought risk
