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 aim of soil solarization is to control soil borne pathogens and weeds heating with solar energy of soil which is sufficiently wetted. Soil water content is the one of the most important factors affecting soil solarization. Humidity level is important to convey temperature from the upper layers to down layers of soil in solarized soil. For this purpose, the study was conducted in plastic greenhouse in Isparta province. Beginning of the study, all plots were irrigated to reach the field capacity, and then the all plots were irrigated in 5 days irrigation interval during the experiment periods. Temperature distribution was measured in 5, 10, 20 and 30 cm of the soil profile along the experiment periods. As a result of this study, increasing of soil temperature and effectiveness of solarization decreased with together the water content of soil in upper layers. However, the soil temperature increased with irrigation in the down layers.

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.

Opis:
The objective of the work was to evaluate, by using the micromorphometric method, the effects of reclamation on porosity of two different clay loam soils irrigated with saline-sodic waters. Soil samples of the Ap horizon were put in cylindrical containers and irrigated with 9 types of saline-sodic waters (3 levels of salinity combined with 3 levels of sodicity). After a 4-year period, correction treatments were initiated by addition of calcium sulphate and leaching until electrical conductivity and sodium absorption ratio values of the drainage water matched 3 dS m-1 and 9, respectively. After 2 years of correction treatments, undisturbed soil samples were taken from the surface layer and soil thin sections for porosity measurements. Both soils did not show critical macroporosity values (> 10%, below this threshold a soil is classified as compact). Nevertheless, the soils exhibiteda different behaviour: total porosity of the Pachic Haploxeroll soil was not affected by difference in water salinity and alkalinity; on the contrary, the Udertic Ustochrept soil showed a lower porosity associated with higher salt concentration in the irrigation waters. This may be due to the different iron and aluminium sesquioxides content and, as a consequence, a different effect on soil aggregate stability.

Study on soil infiltration rate as part of water cycle is essential for managing water resources and designing irrigation systems. The present study was conducted with the aim to compare Kriging, inverse distance weighting (IDW), multilayer perceptron (MLP) and principal component analysis (PCA) methods in the interpolation of soil infiltration in furrow irrigation, and determine the best interpolation method. To conduct infiltration tests, furrows were made on the farm in four triad groups. Infiltration through the blocked furrows method was measured 10, 20, 30, 40, 50, 60, 90, 120, 150, 160, 180 and 210 min after irrigation at a 10-meter distance in each furrow. Data were analyzed by GS+ and Neuro Solutions (NS) software packages. In this study, the maximum error (ME), mean bias error (MBE), mean absolute error (MAE), root mean square error (RMSE), relative error (RE) and correlation coefficient (r) were used to compare the interpolation methods. The results of analysis of variance (ANOVA) indicated that differences in methods based on RMSE, MBE, MAE and ME indices were not significant; however, this difference was significant based on r and RE indices. According to the ANOVA results, it can be said that the PCA method with a r of 0.69 and RE of 31%, was predicted with a higher accuracy as compared to other methods.

Opis:
In many regions of the world, including Egypt, water shortages threaten food production. An irrigation deficient strategy in dry areas has been widely investigated as a valuable and sustainable approach to production. In this study, the dry matter and grain yield of wheat was decreased by reducing the amount of irrigation water as well as the volume of the root system. As a result of this, there was an increase the soil moisture stress. This negatively affected the absorption of water and nutrients in the root zone of wheat plants, which ultimately had an effect on the dry matter and grain yield of wheat. The values of dry matter and grain yield of wheat increased with the ʻSakha 94ʼ variety compared to the ʻSakha 93ʼ class. It is possible that this was due to the increase in the genetic characteristic of the root size with the ʻSakha 94ʼ variety compared to the ʻSakha 93ʼ class, as this increase led to the absorption of water and nutrients from a larger volume of root spread. Despite being able to increase the water productivity of wheat by decreasing the amount of added irrigation water, the two highest grain yield values were achieved when adding 100% and 80% of irrigation requirements (IR) needed to irrigate the wheat and no significant differences between the yield values at 100% and 80% of IR were found. Therefore, in accordance with this study, the recommended irrigation for wheat is at 80% IR which will provide 20% IR. When comparing the water productivity of two wheat varieties in study, it becomes clear that ʻSakha 94ʼ was superior to ʻSakha 93ʼ when adding the same amount of irrigation water, and this resulted in increased wheat productivity for ʻSakha 94ʼ. The SALTMED results confirmed good accuracy (R2: 0.92 to 0.98) in simulating soil moisture, roots volume, water application efficiency, dry matter, and grain yield for two varieties of wheat under deficit irrigation conditions. Whilst using sprinkler irrigation system under sandy soils in Egypt.

W pracy analizowano wpływ czasu i częstości nawadniania gleb ściekami miejskimi na ich wybrane właściwości fizyczne, fizykochemiczne i chemiczne, ze szczególnym uwzględnieniem ilościowych i jakościowych zmian związków próchnicznych. Obiektem badań były gleby pól irygacyjnych wielkiej aglomeracji miejskiej. Przeprowadzone badania wykazały, że irygacja gleb ściekami miejskimi przyczyniła się do zwiększenia zawartości materii organicznej oraz składników biogennych. Zaobserwowano także wyraźną kumulację związków lipidowych i zwiększenie udziału kwasów huminowych w glebach nawadnianych najczęściej. Stwierdzono również, że częsta irygacja ściekami miejskimi gleb lekkich może przyczynić się do degradacji środowiska.
The aim of this study was to analyze how variations in time and frequency of soil irrigation with municipal sewage affect some physical, physicochemical and chemical properties of the irrigated soil, including quantitative and qualitative changes of humic substances. Soils from irrigation fields of a large city agglomeration were selected for this study. Results showed increased concentration of organic matter and nutrients in irrigated soils. The accumulation of lipid substances and humic acids were observed in most frequently irrigated soils. It was found that frequent irrigation of light soils with municipal sewage might lead to environmental degradation.

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:
The issues discussed in the paper concern the assessment of changes in quantitative and qualitative indicators of water resources in the climatic conditions of the southern part of Kazakhstan. For this purpose, many years of systematic field observations and other continuous data obtained from the functioning measurement and observation stations operating within the Aral-Syrdarya Basin Inspection were used. On the basis of the obtained data, indicators were determined that characterize the quantity and quality of water supplied to the soil in the irrigation process, as well as the quantity and quality of water flowing out of the drainage systems, together with an evaluation of the effectiveness of irrigation and drainage systems. Soil salinity was assessed in five irrigated massifs with a total area of 332.55 thous. ha. For the same irrigated massifs, the annual amounts of water taken for irrigation, the amount of outflowing water and the assessment of the mineralization level were determined. Based on the developed results of field observations characterizing the hydrological and environmental situation of the lower section of the Syr Darya River in 1960–2015, the negative reaction coefficients were calculated for the local population, soil and vegetation for five of the irrigated massifs of the Kyzylorda region. The ecological situation of the habitat of soil and plants in the lower reaches of the Syr Darya River in all irrigation areas deteriorates on a time scale, since as a result of the reclamation of agricultural lands, intensive secondary soil salinization occurs and the formation of infiltration runoff with high mineralization, contributing to the violation of the harmonization of the relationship between nature and man.

Based on available literature, we collected and presented in tables the values of optimal precipitation (for some field-cultivated vegetables) which are still sometimes used in Poland. We also included a short summary of how they are defined and how the necessary corrections are introduced. Included optimal precipitation values have been developed by: Dzieżycet al., Grabarczyk, Klatt and Press. Therefore, it is possible to define (estimate) precipitation deficits for specific species of vegetables depending on the temperature or soil weight classification (light, medium, heavy) in various regions of Poland. By recognising optimal precipitation, we can plan, design or introduce irrigation and manage it. The formulas developed by Grabarczyk offer an additional possibility of calculating expected average increase (growth) of vegetable crops as a result of irrigation within various precipitation zones in Poland.
