Opis:: Water shortages occurring in the natural environment are the result of progressing climate changes, including the decreasing amount of atmospheric precipitation. In Poland, during the vegetation periods, droughts occur every 4-5 years, which causes losses in the field production and in forest communities. Reducing the negative effects of drought is possible by retention of water within a catchment. This method of improving the water balance has been included in the provisions of the Water Framework Directive and Water Law. On the meliorated valley objects, there are melioration devices that enable regulation of the moisture content, including irrigation during periods of drought. Drainage ditches can also retain water in the early spring periods with high flows in rivers. The studies carried out on the Lower Supraśl river site showed that about 40% of drainage devices used for water damming (dams and ramps), as well as for water distribution (feeders and detailed ditches) are not technically efficient and do not fulfil the function of moisture content regulation. Fibrous-muck soils occurring on this object, due to the lack of rainfall and irrigation, reduced the water retention capacity by approximately 30%. Modernization and reconstruction of drainage devices on valley objects will enable increasing the retention within individual catchments.

Opis:: Drought is generally associated with the persistence of low precipitation amount, decreased soil moisture and water availability relative to the normal levels in a designated area. The effects of drought, range from the morphological to molecular levels, and are evident at all phenological stages of the plant growth, at whatever stage the water deficit occurs. Determination of the surface water demands for irrigation purposes comes out from the assumption of hydrologic processes stationarity. This paper shows our research prerequisite that water stress participates in an important part on the volume changes of over ground parts, which is predictive for the irrigation demand. Malus domestica var. Yellow Transparent was chosen for the measurement of volume changes of the surface plant parts. Our measurements were realised by the Diameter dendrometer small (DD-S) from 24.08. to 13.09.2017. One tree was irrigated by the dose of 50 mm. We compared the dendrometric changes to soil moisture and rainfall on both irrigated and non-irrigated trees. The experiment showed the differences between the irrigated apple tree (the diameters of the branches fluctuated between 11.9 and 12.1 mm) and the non-irrigated apple tree (the diameter of the branches increased after three-day rain from 8.35 to 8.61 mm), in order to determine the water stress of plants based on dendrometric changes and optimize irrigation during the drought period.

Tytuł:: The Relationships of Texture and Hydrophysical Properties in Soil Profiles Under Selected Exotic Trees in the Context of Climate Change in Central Europe

Tematy:: available water

Opis:: Suitable soil and environmental conditions are the main prerequisites for successful growth of plants. Generally, all soil properties are substantially affected by textural composition. Therefore, the objective of the study was to test the interrelationships between particle size distribution and such physical soil properties, which usually predetermine the survival/death of plants, since they significantly affect the content and availability of water and air. Textural composition and physical soil properties were studied in profiles under monocultures of selected exotic trees in Arboretum Mlyňany, Slovakia. The results showed that medium-textured dominated in topsoils, whereas heavy-textured classes were dominant in luvic and stagnic horizons. Evaluation of entire profiles had confirmed standard, expected relationships between the individual grain fractions and soil physical properties. However, differences have occurred when the correlations between texture and physical properties in individual horizons were evaluated. Considering entire soil profiles, increased sand content significantly supported drainage of rainwater and soil aeration; silt contributed to increase the total porosity and aeration as well as available water capacity; clay contributed to the decrease in the available water capacity, total, and particularly coarse porosity and aeration, and to rise water retention, as well as the values of the wilting point. The results showed silt as key fraction providing suitable hydrophysical properties for the survival and growth of trees introduced in Arboretum. In compacted luvic and stagnic horizons, silt was significantly involved in the formation of total, and particularly coarse porosity and thereby increase soil aeration, while conversely, in loose topsoils just silt fraction significantly contributed to the reduction of coarse pores and increase of fine capillary pores and therefore water retention. In loose eluvial horizons, the silt contributed to significant increases in capillary porosity and water availability, which is essential in terms of meeting the plant needs.

Opis:: The studies on agricultural droughts require long-term atmospheric, hydrological and meteorological data. On the other hand, today, the possibilities of using spectral data in environmental studies are indicated. The development of remote sensing techniques, increasing the spectral and spatial resolution of data allows using remote sensing data in the study of water content in the environment. The paper presents the results of the analysis of moisture content of soil-plant environment in the lowland areas of river valley using the spectral data from Sentinel-2. The analyses were conducted between February and November 2016. The spectral data were used to calculate the Normalize Differential Vegetation Index (NDVI) which provided the information about the moisture content of the soil-plant environment. The analyses were performed only on grasslands, on 22 objects located in the research area in the Oder river valley between Malczyce and Brzeg Dolny, Poland. The NDVI values were correlated with the hydrological and meteorological parameters. The analyses showed spatial and temporal variability of the moisture conditions in the soil-plant environment showed by the NDVI variability and existence some relationships between the climatic and spectral indices characterizing the moisture content in the environment.

Opis:: W artykule przedstawiono systemy monitoringu środowiska przyrodniczego o zasięgu ogólnokrajowym, związane ze środowiskiem gruntowym. Pierwszy to monitoring chemizmu gleb ornych, ujawniający jakość gleb rolniczych w Polsce. Monitorowane jest 216 punktów. Problem stanowi głównie zakwaszenie gleb oraz niedobór przyswajalnego fosforu. Drugi to monitoring suszy rolniczej. Jest oparty na wyznaczaniu klimatycznego bilansu wodnego w powiązaniu ze zdolnościami retencyjnymi gleb. Stwierdzenie suszy uprawnia do uzyskania państwowej pomocy finansowej. Trzeci to monitoring osuwisk, który dotyczy głównie obszaru Karpat Polskich. Wyznaczane są tereny zagrożone ruchami gruntu, a w obrębie osuwisk analizowane są przemieszczenia powierzchniowe (pomiary GPS) i wgłębne (pomiary inklinometryczne). Opisano zakres każdego monitoringu, a także podano liczne informacje metodyczne. Zwrócono uwagę na praktyczne aspekty działań monitoringowych. Wyniki każdego monitoringu są w różnym zakresie dostępne do wiadomości publicznej, co umożliwia ich dyskutowanie.
The article presents nationwide environmental monitoring systems related to the ground environment. The first system is the monitoring of chemical properties of arable soil, aiming to estimate the quality of agricultural soils in Poland. Totally 216 points are being monitored. The problem is mainly soil acidification and a deficiency of available phosphorus. The second one is monitoring of agricultural drought. It is based on the determination of the climate water balance in connection with soil retention capacity. When a drought is confirmed it entitles to receive state financial assistance. The third system is the landslides monitoring, which mainly concerns the area of the Polish Carpathians. The areas endangered by ground movements are indicated, and within landslides surface of ground displacements (GPS measurements) and deep movements (inclinometric measurements ) are analyzed. The scope of each monitoring was reviewed, as well as numerous methodological information was given. The attention was paid to practical aspects of the monitoring activities. The results of each monitoring are available to be public message in varying degrees, which makes it possible to discuss them.
