INFORMATION MATERIALS FOR ASSESSING THE IMPACT OF CLIMATE FACTORS ON FORMING SOIL WATER REGIME ON DRAINED LANDS

Keywords: climate change, drained lands, precipitation, air temperature, information materials, soil water regime

Abstract

The research results on creating information materials for assessing the impact of modern climatic factors on the formation of soil water regimes on drained lands are presented. By the results of the research, carried out at the "Romen" drainage and irrigation system (Sumy region), it was established that over the past 34 years, the average air temperature during the growing season has varied from 14,2 to 19,4 oC. In general, there is a trend for its slight decrease (almost by 0,2 oC). The highest average monthly air temperatures are recorded in July and August, and the lowest ones - in April. It was specified that the water regime of the active soil layer during the growing season is formed mainly due to moderate (4–14 mm – 44%) and significant (15–49 mm – 40%) precipitation, the total share of which in water reserves is 84%. There is a trend towards an increase in the share of significant precipitation (on average, up to 46–60 % of the total amount during the growing season) in years with high-water growing seasons, and its predominant amount falls in the range of 15–29 mm. There is also an increase in the share of moderate precipitation (up to 49% of the total amount during the growing season) in years with low-water growing seasons.

Information materials on the distribution of atmospheric precipitation by year in quantitative and percentage indicators, their recurrence in the growing seasons of 1990–2022 ("Romen" DIS, Sumy region), presented as an interactive visual report with graphic materials (dashboard) have been created. Informational materials in the form of dashboards enable us to monitor changes in climatic conditions, promptly providing up-to-date data when forecasting future trends in changes in the water supply of agricultural territories, in particular, the formation of the soil water regime on drained lands and addressing the challenges related to climate change.
