Communication report regarding the incidences of drought conditions in Poland
Year: 2009; period: 10 (1.VII - 31.VIII)
IUNG-PIB Puławy has calculated the climate water balance (CWB) for the period 1 July to 31 August 2009 for 3,064 Polish communities and identified the current state of agricultural drought for the following crops: maize for grain and silage, potatoes, sugar beet, hops, tobacco, vegetables, fruit trees and shrubs, as well as leguminous crops.
Based on the calculated values of climatic water balance (CWB) for the Poland, the tenth reporting period, from 1 July to 31 August 2009, we found the occurrence of agricultural drought for leguminous crops grown on very light soils.
A previous report raised the fact of an increase of water shortage in some parts of Poland. This trend is still maintained - causing a risk of drought for leguminous crops. The threat is not related to species with short vegetation such as pea and lentil, because the first half of July, these were harvested. Shortage of precipitation in the above-mentioned period could have a significant adverse effect on the yield of blue lupine, gathered mostly at the end of July. A risk of a drought occurring in July, affects more species of leguminous plants with a longer vegetation season such as Vicia faba L. ssp. minor, yellow and white lupine, which are usually harvested in mid-August and varieties with a longer growing season sometimes up to the second half of August. Drought occurrence at the present time is no longer a threat to grain legumes as they have reached full maturity, and should no longer be collected from the field.
Agricultural drought risk for legumes has occurred in the area of Wielkopolska (western part) and in the eastern Lubuskie and Lubelskie voivodeship's. The drought occurrence for legumes represents 1.7% of the country area, the drought risk is occurring in 252 Polish counties, 8.2% of all the counties of the country.
Current CWB values across the country are much lower, by several to tens of millimeters in relation to previous reporting period. The biggest drop in the CWB value occurred in the Dolnośląskie, Opoleskie, Śląskie, Wielkopolskie, Lubuskie, Lubelskie (eastern part) voivodeships. Currently CWB values across the country are already negative.
In the last sixty days period (from 21 to 31 August) in Poland, a large variability of precipitation had occurred. Absence of precipitation or a few millimeters of rainfall occurred in the voivodeships of Lubuskie, Kujawsko-Pomorskie, Wielkopolskie, Kujawsko-Pomorskie, Pomorskie southern part, western part of the Warmia and Mazury, Lubelskie (East) - causing a further increase in water scarcity. By contrast, high precipitation (above 50 mm) occurred in Małopolskie, Mazowieckie, Podlaskie and Lubelskie (north-western part).
