Communication report regarding the incidences of drought conditions in Poland

Year: 2018; period: 06 (11.V - 10.VII)

The Institute of Soil Science and Plant Cultivation – State Research Institute, in accordance with an Act of the Minister of Agriculture and Rural Development has developed the climatic water balance values for all 2478 Polish local districts (gminas) and, on the basis of soil categories, calculated the current risk of agricultural drought for the following crops: winter and spring cereals, maize for grain and maize for silage, rape and turnip rape, potato, sugar beet, hops, tobacco, ground vegetables, fruit shrubs and trees, strawberries and legumes (fabacea).

In the sixth reporting period, i.e. from May 11th to July 10th 2018, IUNG-PIB stated agricultural drought conditions in Poland.

The mean of Climatic Water Balance values, which are the basis for assessing the risk of agricultural drought, was negative and reached -178 mm. In relation to the previous reporting period it has dropped by 3.5 mm.

The lowest CWB values in this sixty-day reporting period were still recorded in Poznań and the surrounding area, which has grown significantly. The CWB values ranged there from -260 to -269 mm. A very high water deficiency ranging from -240 to -249 mm was still recorded in the Lowlands: Wielkopolska, Szczecińska, and in Żarnowiecka Upland. Increasing water shortage was recorded in vast areas of Pomeranian Lake District, where it has grown by 40 mm. Considerable water deficiency occurred also in Kujawy, where it ranged from -200 to -239 mm. In the eastern part of Masurian Lake District water deficiency has decreased by 30 mm, and in the southern part of Masovia and northern part of Lubelskie it dropped by ca. 20 mm. Considerable water shortage exceeding 160 mm was recorded to the north of the Polish Uplands, while in the southern regions of Poland it was much lower, reaching from -50 to -100 mm.

In the current reporting period drought occurs in all the monitored crops:

  • Rape and turnip rape
  • Spring cereals
  • Legumes (fabacea),
  • Fruit shrubs,
  • Winter cereals,
  • Tobacco,
  • Strawberries,
  • Ground vegetables,
  • Maize for grain,
  • Maize for silage,
  • Fruit trees,
  • Hops,
  • Potatoes,
  • Sugar beet

May was particularly warm this year. In Wielkopolskie and Mazurskie Lake Districts the air temperature exceeded the norm by 4°C, and in the rest of the country by 3-4°C. The highest temperatures were recorded in the centre of Poland, ranging from 17 to 18°C, and in the vast majority of the country between 16 and 17°C. In the north the temperatures were the lowest, from 13 to 16°C.

The first decade of June was warm as well. In the western part of the country temperatures reached from 20 to even 20.5°C. In the rest of the areas temperatures were also considerably high, between 17 - 20.5°C. The second decade of June was similar, temperatures reached 19 to 20.5°C. Only in the north of the country it was slightly colder, 16.5 to 19°C. The third decade of the month was much colder in all the areas. In the majority of the country temperatures ranged from 15 to 16°C. Only in the north-eastern and north-western regions it was slightly warmer, from 16.5 to 17.5 C.

The first decade of July was not very warm either, with temperatures reaching from 17 to 19°C. The lowest temperatures were recorded in the north-eastern part of the country: 16.5-17°C, and the highest in the south-western regions: 19-19.5°C.

In May precipitation varied significantly, from very scarce (20-30 mm) in Lubusz Land, Greater Poland Lake District and Podlasie, to very intense (60-100 mm) rainfalls in Lesser Poland Upland. In the vast majority of the country precipitation was 10-50% lower than the norm. In Lubusz Land and the central part of Pomeranian Lake District precipitation in May constituted 30-50% of the norm, while in the Lesser Poland Upland it was even 90-110%.

In the first decade of June precipitation varied across the country, from very low in the east of Poland (below 5 to 10 mm) to considerably high in the west and south (10 to more than 50 mm). In the second decade precipitation was very scarce (up to 5 mm) or there was even a complete lack of rainfall in the north of the country. In the south of Poland precipitation ranged from 5 to 50 mm (especially in the south-eastern part of the country).

In the third decade of the month precipitation was more intense, reaching 15-50 mm in the majority of the country or even exceeding 50 mm in the south. Only in the north-western regions precipitation was scarce, reaching 5 to 15 mm, and there were still some areas with a complete absence of rainfall.

The first decade of July was characterized by very scarce precipitation in the majority of the country, reaching the maximum of 10 mm, or absence of precipitation in some regions. Only in the eastern and western regions of Poland it reached 10-20 mm.

May and the two decades of June were characterised by particularly high temperatures and insolation (especially in the north of the country). The values of the abovementioned meteorological factors were considerably higher than multiannual norms. At the same time precipitation in this period was considerably low. The third decade of June and the first decade of July, however, were colder. In the first decade of June precipitation was quite abundant in the majority of areas, but in the first decade of July precipitation was lower, which resulted in a slight decrease of the mean of Climatic Water Balance values. It also contributed to the growing water deficiency for many species and groups of plants. Constant water deficiency caused agricultural drought in all the fourteen monitored crops. In the current reporting period there has been an increase in both the area and the number of local districts affected by drought in the following crops: rape and turnip rape, hops, potato, sugar beet and maize for grain and silage.
