Opis:
The ash-leaved maple (Acer negundo L.) has low habitat requirements, which is why this species is often used in the reclamation of industrial areas. The development of the reclamation plantings depends on the optimal water soil conditions that can be controlled by watering treatments. However, the use of irrigation requires determining the water needs of the cultivated species. The objective of the study was to evaluate the water needs of the ash-leaved maple in the reclamation plantings, in the period of over three years after planting. The water needs of the ash-leaved maple were determined using the crop coefficients method. Potential evapotranspiration was calculated using the Blaney-Criddle’s formula that was modified for the Polish conditions by Żakowicz. The water needs of the ash-leaved maple were assessed for five agro-climatic regions of Poland, in the years 1981-2010. The water needs of the ash-leaved maple in the growing period (April-October) were the highest in the C-E (638 mm) and C-N-W (637 mm) regions, and the lowest in the N-E (598 mm) and S-E (601 mm) regions. In July, the highest water needs were noted in the C-N-W region (149 mm) and the lowest in the S-W region (129 mm). In the studied thirty-years period, there was a significant upward trend in the water needs of the ash-leaved maple both during the growing season (except for the C-N-W region) and in July, in all the considered regions.

Opis:
The purpose of the present study was to determine the water needs of bird cherry (Padus avium Mill.) over three years after planting on the reclaimed areas. The estimations were performed for the period of two months, including July and August, which are critical in terms of the amount of water available to the plants. The water requirements of bird cherry plants were calculated in the years 1981-2010 for five agro-climatic regions of Poland with the representative meteorological stations located in Olsztyn, Bydgoszcz, Warsaw, Wrocław and Krakow. The bird cherry water needs were determined using the plant coefficient method. The plant coefficients for bird cherry trees over three years after planting were adapted to the reference evapotranspiration that was calculated using the Blaney-Criddle’s formula, modified for Polish conditions by Żakowicz. The rainfall deficit with the probability of occurrence of average dry years (N50%), medium dry years (N25%) and very dry years (N10%) was determined according to the Ostromęcki’s method. On average, in the years 1981-2010, in July and August, the highest water needs of bird cherry trees, grown on the reclaimed areas over three years, were estimated in the central-north-west (271 mm) and central-east (270 mm) region of Poland. While, the lowest water requirements of bird cherry (240 mm) in the south-east region of the country was calculated. In August, the highest bird cherry water needs (121 mm) were estimated also in the central-north-west and central-east region of Poland, whereas the lowest water requirements (111 mm) occurred in the south-east region of the country. In each considered region of Poland, in the years 1981-2010, a visible increase in bird cherry water needs in the period of the highest water requirements, was noted. With the exception of the central-north-west region of the country, the temporal variability of bird cherry water needs was significant throughout Poland. The highest increase of the water requirements (by 6.7 mm per every ten-year period) in the south-east region of Poland was found. In the period covering July and August, the highest rainfall deficit, 131 and 133 mm, in the average dry years (N50%) was noted in the central-east and central-north-west region of Poland, respectively. In the north-east, central-north-west and central-east region of the country, the rainfall deficit in the medium dry years (N25% ranging from 206 to 214 mm) and very dry years (N10% ranging from 269 to 300 mm) was higher than in the south-west and south-east region of Poland (N25% ranging from 146 to 159 mm and N10% ranging from 195 to 211 mm).
Celem przedstawionych badań było oszacowanie zapotrzebowania na wodę czeremchy zwyczajnej (Padus avium Mill.) w okresie powyżej trzech lat po wykonaniu nasadzeń na obszarach objętych rekultywacją. Obliczenia przeprowadzono dla okresu obejmującego dwa miesiące, lipiec i sierpień, które są krytyczne pod względem ilości wody dostępnej dla roślin. Wymagania wodne roślin czeremchy zwyczajnej zostały oszacowane w latach 1981-2010 dla pięciu agro-klimatycznych regionów Polski wraz z reprezentatywnymi stacjami meteorologicznymi zlokalizowanymi w Olsztynie, Bydgoszczy, Warszawie, Wrocławiu i Krakowie. Potrzeby wodne drzew czeremchy zwyczajnej zostały określone za pomocą metody współczynników roślinnych. Współczynniki roślinne dla drzew czeremchy zwyczajnej w okresie powyżej trzech lat po wykonaniu nasadzeń na obszarach objętych rekultywacją dostosowano do ewapotranspiracji wskaźnikowej, którą obliczono za pomocą wzoru Blaneya-Criddle'a, zmodyfikowanego dla warunków polskich przez Żakowicza. Niedobory opadów atmosferycznych z prawdopodobieństwem wystąpienia roku przeciętnie suchego (N50%), roku średnio suchego (N25%) oraz roku bardzo suchego (N10%) oznaczono za pomocą metody Ostromęckiego. Średnio, w latach 1981-2010, w okresie od 1 lipca do 31 sierpnia, najwyższe zapotrzebowanie na wodę drzew czeremchy zwyczajnej w okresie powyżej trzech lat po wysadzeniu na obszarach zrekultywowanych obliczono w centralno-północno-zachodnim (271 mm) oraz centralno-wschodnim regionie Polski (270 mm). Z kolei najniższe zapotrzebowanie na wodę czeremchy zwyczajnej (240 mm) wystąpiło w południowo-wschodnim regionie kraju. W sierpniu najwyższe zapotrzebowanie na wodę drzew czeremchy zwyczajnej (121 mm) obliczono również w centralno-północno-zachodnim oraz centralno-wschodnim regionie Polski, natomiast najniższe zapotrzebowanie na wodę (111 mm) wystąpiło w południowo-wschodnim regionie kraju. We wszystkich rozpatrywanych regionach Polski, w okresie od 1981 do 2010, odnotowano tendencję do zwiększania się potrzeb wodnych czeremchy zwyczajnej w czasie największego zapotrzebowania na wodę, czyli w lipcu i w sierpniu. Z wyjątkiem centralno-północno-zachodnim regionu Polski, trend zmienności czasowej potrzeb wodnych czeremchy zwyczajnej był istotny we wszystkich pozostałych regionach kraju. Najwyższy wzrost zapotrzebowania na wodę (o 6,7 mm w każdym kolejnym dziesięcioleciu) wystąpił w południowo-wschodnim regionie Polski. W okresie od 1 lipca do 31 sierpnia największe niedobory opadów atmosferycznych, 131 i 133 mm, w przeciętnie suchym roku (N50%) odnotowano odpowiednio w środkowo-wschodnim oraz środkowo północno-zachodnim regionie Polski. W północno-wschodnim, środkowo-północno-zachodnim i środkowo-wschodnim regionie kraju niedobory opadów atmosferycznych w średnio suchym roku (N25% w zakresie od 206 do 214 mm) i w bardzo suchym roku (N10% w przedziale od 269 do 300 mm) był wyższy niż w południowo-zachodnim i południowo-wschodnim regionie Polski (N25% od 146 do 159 mm i N10% od 195 do 211 mm).

Opis:
The aim of this study was to estimate the water needs of grapevines (Vitis vinifera L.) in the different regions of Poland. The requirements of grapevines water, considered as the crop evapotranspiration, were determined using the plant coefficient method. The grapevine plants crop evapotranspiration was measured using the reference evapotranspiration and plant coefficients. The plant coefficients were adapted to the reference evapotranspiration that was calculated using the Blaney‑Criddle’s formula, modified for Polish conditions by Żakowicz. The water needs of grapevines were determined for five agro‑climatic regions of Poland with the representative meteorological stations. The calculations of grapevines water requirements were carried out for the thirty‑year period determined from 1981 to 2010. The study was based on the six‑month growing season established from May 1 to October 31. Four months, including May, June, July and August, were considered as the irrigation period. The highest grapevines water requirements (440 mm) during the growing season, were observed in the north‑west and central‑east region of Poland. In turn, the lowest water requirements were revealed in the south‑east (414 mm) and north‑east (415 mm) region of the country. During the irrigation period, the highest grapevines water needs occurred in the central‑north‑west (355 mm) and central‑east (353 mm) region of Poland, while the lowest (329 mm) – in the south‑east region of the country. The upward time trend of the grapevines water requirements was observed both in the growing season and in the irrigation period. With the exception of the central‑north‑west region, this time trend was significant throughout Poland. The highest increase in the water needs of grapevines during the growing season (by 6.9 mm in each subsequent ten‑year period) occurred in the central‑east and south‑east region of Poland. In the irrigation period, the highest rise of grapevines water requirements was noted in the south‑west (7.4 mm decade ‑1) and south‑east (7.6 mm decade ‑1) region of the country. The highest rainfall deficit was observed in the central‑north‑west region of Poland; 125 mm during the growing season, and 117 mm in the irrigation period.

Opis:
According to the SRES A1B climate change scenario, by the end of the 21st century temperature in Poland will increase by 2–4°C, no increase in precipitation totals is predicted. This will rise crop irrigation needs and necessity to develop irrigation systems. Due to increase in temperature and needs of sustainable agriculture development some changes in crop growing structure will occur. An increase interest in high protein crops cultivation has been noted last years and further extension of these acreage is foreseen. Identifying the future water needs of these plants is crucial for planning and implementing sustainable agricultural production. In the study, the impact of projected air temperaturę changes on soybean water needs, one of the most valuable high-protein crops, in 2021-2050 in the Kuyavia region in Poland was analysed. The calculations based on meteorological data collected in 1981-2010 were considered as the reference period. Potential evapotranspiration was adopted as a measure of crop water requirements. The potential evapotranspiration was estimated using the Penman–Monteith method and crop coefficient. Based on these estimations, it was found that in the forecast years the soybean water needs will increase by 5% in the growing period (from 21 April to 10 September), and by 8% in June-August. The highest monthly soybean water needs increase (by 15%) may occur in August. The predicted climate changes and the increase in the arable crops water requirements, may contribute to an increase in the irrigated area in the Kuyavia region and necessity of rational management of water resources.
