Opis:: In the present work, the dried biomass of soil isolated fungus Eurotium cristatum was used for synthesizing silver nanoparticles (AgNPs). The synthesized AgNPs were spherical in shape with average diameter of 16.56 nm and displayed maximum absorbance at 418. Fourier transform infrared (FTIR) study indicated the presence and binding of proteins with myco-produced silver nanoparticles. The optimum conditions for AgNPs biosynthesis were found to be at temperature of 40°C, pH of 8.0, substrate concentration of 500 ppm and fungal biomass wt. of 0.8 g. The AgNPs showed antibacterial activity against Staphylococcus aureus, Listeria monocytogenes, Escherichia coli and Shigella flexneri. AgNPs was built-in thin film nanocomposite (TFNC) membrane and the impacts of nanomaterial composition on membrane properties and desalination process were studied. The AgNPs produced membrane TFNC had better filtration performances than pure thin film composite membrane TFC. The TFNC membrane had enhanced water flux (32.0 vs. 16.5 dm³∙m^–2∙h^–1) and advanced NaCl rejection (91.7 vs. 89%) compared to the TFC membrane. A pot experiment was conducted to evaluate the effect of the irrigation with desalinated water on yield and productivity of essential oil of the sweet basil (Ocimum basilicum L.) and lavender (Lavandula multifida L.). The irrigation with desalinated water reduced significantly the soil reaction, soil electrical conductivity (EC), sodium adsorption ratio and exchangeable sodium percent in rhizospheric soil, it also enhanced the growth and oil yield of both plants compared with those irrigated with salt water.

Opis:: Methodical questions of monitoring of water status in soil, cereals grain and wood are discused ( where monitoring is understood as registration of time and spatial variability of selected properties). Amount of viariables which is necessary in order to determine water status depends on the complexion of the considered phenomena and is, so far, the matter of arbitrary choice. In most practical cases the water status is expressed only by moisture of the considered material ( like the building timber). In practical terms, two variables suffice to express water status in cereal grain: moisture and temperature. To describe water status in the soil not less then five variables are needed: amount of water (the soil moisture) soil water potential, salinity, oxygenation and temperature. The only sensors that can be integrated in modern data acquisition system must be read electrically. Therefore electroresistance and electrocapacitance methods were considered. Dielectric sensors were recognized as the proper choice.Soil is a complex material having instable characteristics. For this reason it is the most difficult task to monitor soil water status, particularly to determine the soil moisture. Therefore it has been assumed that measuring methods verified for the soil will be also suitable for other, less complex materials. Thus, monitoring of soil water status was mainly discussed. Special attention was focused to the time domain reflectometry, TDR, as the semi selective method for the soil moisture and salinity determination.

Opis:: Forestry management in anthropo−transformed habitats is characterized by a very high risk. The formation of waste as well as flooding of tree stands by salty water from different sources of mining and processing of coal is an important issue on the industrial areas. The introduction of the pollution load in the form of saline water leads to increased soil salinity, which can damage or cause the dieback of individual trees, tree stands and whole forest ecosystems. The aim of the research was to (i) analyze the changes in forest soils on the area flooded by water leaked from the waste reservoir, (ii) assess the possibility of this soil self−purification from chlorides and sulfates and (iii) estimate the possibility of reclamation of this land for forestry purposes. The study was conducted in Katowice Forest District (southern Poland). Soil samples for physico−chemical analysis were collected in 2015. The results of chemical analyzes of surface soil layers made in 2013 and 2014 were also used. The content of chlorides and sulphates in the soil was used as one of the key indicators to assess the level of soil salinity. In the year of the damage occurrence, in surface horizons it significantly exceeded the threshold value, but declined in subsequent years to a level below this value even in the area of the greatest damage. However, our analysis indicate an accumulation of chlorides and sulphates in the soil at a depth of 100−120 cm, as well as the accumulation of sodium cations. This demonstrates the difficulties with the self−purification of soil or continuous supply of pollutants from the waste reservoir. Currently, surface soil horizons meet the criteria of not−salinized soils, which does not indicate a need for change in land use. After the surface preparation and technical work used in forestry practice, the damaged area can be designed for the reintroduction of forest trees.

Opis:: Do zbiornika wód kopalnianych "Bojszowy" odprowadzano solanki z kopalń "Piast" i "Czeczott". Pomimo jego wyłączenia z eksploatacji w dalszym ciągu obserwuje się zasolenie gleb w jego otoczeniu. Zasięg oddziaływania zbiornika ogranicza się przede wszystkim do terenów przyległych po stronie południowej. W glebach stwierdzono wyższe zawartości niektórych składników śladowych: As, Ba, Co, Cr, Pb od dopuszczalnych, określonych w Rozporządzeniu Ministra Środowiska z dnia 9 wrzenia 2002 roku. Badania wykazały, że źródłem szkodliwych metali w glebach nie mogły być solanki kopalniane.
The brine from "Piast" and "Czeczott" mines had been drained to the mine water reservoir "Bojszowy". Despite of its exclusion from exploitation, the soil salinity is still observing in its surroundings. The range of impact of this reservoir is limited mostly to the nearby grounds on its south side. In the soils greater levels of some traceable components than permissible, defined in Ministry of the Environment Decree of 9th September 2002, were detected: As, Ba, Co, Cr, Pb. Test showed that the source of the harmful metals in soils could not be mine brine.

Opis:: Scarcity of fresh water resources is the major constraint for agricultural development in Iran as in many other regions with arid and semi-arid climate. With the pressure on fresh water resources, the use of un-conventional water resources including brackish, saline and sewage water has received greater attentions in recent years. The objective of this study was to assess the impact of farmers' practices using saline groundwater on wheat yield and soil salinity in a Mediterranean climate of Fars province in southern Iran. The study was carried out in several commercial wheat production regions for two years. Chemical analysis of irrigation waters, volume of applied irrigation water, electrical conductivity of soil saturation extract (ECe) and yield were measured in each field. General information on agronomic practices was also collected using a questionnaire. Results demonstrate that waters with salinities higher than what has been classified as “suitable for irrigation” are being used for the production of wheat crop. Analysis of wheat yield response to saline irrigation water showed that for water salinities up to 10.7 mS∙cm^–1 (threshold value) variation in yield was relatively minor, above which wheat yield decreased at a greater rate. Root zone salinity profiles showed the effect of winter rainfall in reducing soil salinity. It is concluded that although acceptable yields are obtained with some of the highly brackish waters, over application of these waters would threaten the sustainability of crop production in the region.

Opis:: The water regime is the main factor contributing to the formation of landscapes in the river deltas of arid zones, any fluctuations in which lead to a change in the integral hydromorphic landscape. After the construction of the Kapshagai reservoir, the anthropogenic load on the ecosystem of the Ili River delta increased, as a result of which degradation processes, such as drying out and salinization, intensified. In the short term, this phenomenon may lead to the desertification of about 1 million ha of land in the modern river delta. In this regard, the main goal of this study is to look at the processes of desertification in the modern delta of the Ili River, using remote sensing data, which allows for quick identification of the long-term dynamics of degradation processes. For this, the authors used satellite data from Landsat 1–5 MSSS and Landsat 8OLI satellites for 1979 and 2019 and soil analysis data obtained through the ground (field) surveys. Using regression analysis of space and soil data, predictors for interpreting space images were identified and maps of landscape drying and soil salinization were compiled, reflecting the changes that have occurred over the past 40 years. As a result, it was found that in 2019, compared to 1979, the area of landscapes covered with vegetation had decreased by 12% and there was a transformation of hydromorphic landscapes into salt marshes and solonetzes. Over the past 40 years, the volume of non-saline soils has decreased by 41.3% and the volume of saline soils has increased to varying degrees. That is, at present, on the territory of the modern delta, a difficult land improvement situation has developed associated with the cessation of spring and summer floods due to the intensive water use at the Chinese and Kazakh sides.
