SPATIAL VARIABILITY OF METEOROLOGICAL AND AGRICULTURAL DROUGHT IN BYDGOSZCZ-TORUŃ REGION
Keywords: meteorological drought, agricultural drought, standardized precipitation index SPI, crop drought index CDI.
Abstract: The spatial variation of meteorological and agricultural drought in the Bydgoszcz-Toruń region in the cultivation of sugar beet, late potato and on permanent grasslands are presented in the paper. The analysis were conducted on the basis of measurements carried out in 2011 at the meteorological stations of the Institute of Technology and Life Sciences in Bydgoszcz, the University of Technology and Life Sciences in Bydgoszcz and Nicolaus Copernicus University in Toruń. Research area is characterized by small sums of rainfall during the growing season and big temporal and spatial variability. The intensity of meteorological drought in each month of the growing season (April–September) was assessed using the Relative Precipitation Index (RPI) and the Standardized Precipitation Index (SPI). Agricultural drought intensity was determined using the linear regression equations between the SPI and Crop Drought Index (CDI). The intensity of agricultural drought during the period was verified by periodic measurements of moisture of soil (in the 0–20 cm layer). At the same time it was found considerable spatial variation of meteorological drought and little spatial diversity of agricultural drought, the intensity of which depended on the available soil water.
