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.

Opis:: The Coastal Chaouia region is located south of the Casablanca city (Morocco). Since the 1970s, groundwater has been used intensively for irrigation, previously for growing citrus and currently for vegetables and forages. The increase of irrigated soils by pumping has induced environmental problems such as the degradation of groundwater quality and salt water intrusion. For these reasons, this work aimed to study the impact of the irrigation water quality upon the agricultural soils. During the study, 71 samples of well water and soil were taken to represent the whole considered area, which comprised 3 different zones (0–1.8 km, 1.8–4.5 km, and 4.5–11 km from the coast). The analyzed parameters were salinity and pH. The results showed firstly that the soil pH average values decrease for the three zones with 7.73, 7.57, and 7.52, respectively. However, the water pH averages vary from 7.24 to 7.49. For the soil electrical conductivity, it represents a light decrease moving from the nearest zone to the sea to the far one (average of 3.54, 2.66, and 2.33, respectively). A similar result is for observed water electrical conductivity with average of 6.83, 5.30, and 2.06, respectively, for the three zones. The analyses of the soil and water salinity show that both salinities decreased moving from the coast to inland. Richard and Wilcox charts have confirmed the strong mineralization and the poor quality of most of the well water which are close to the sea.

Tytuł:: The Influence of Drainage Devices and Post-Bog Soil Changes on Water Retention in Drained Lower Supraśl River

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.
