Opis:
The aim of this study was to assess the impact of the reuse of purified wastewater from the wastewater treatment plant in the city of Settat on the physicochemical quality of agricultural soils compared to the agricultural soils irrigated by rainwater in the region of Chaouia in Morocco. The results obtained showed that despite the great fertilizing value of the purified wastewater, a slight increase in salinity was noted; they also reveal a significant difference in pH. The accumulation of sodium, total limestone and active limestone in the soil increased significantly in the soils irrigated by treated wastewater; in contrast, calcium increased significantly in the soils irrigated by rainwater.No significant differences were recorded for humidity, electrical conductivity, ammonium, nitrates, phosphorus, potassium, organic matter, total nitrogen or cation exchange capacity.

Opis:
Soil salinity is one of the most important problems of land degradation, that threatening the environmental, economic and social system. The aim of this study to detect the changes in soil salinity and vegetation cover for Diyala Governorate over the period from 2005 to 2020, through the use of remote sensing techniques and geographic information system. The normalized difference vegetation index (NDVI) and salinity index (SI) were used, which were applied to four of the Landsat ETM+ and Landsat OLI satellite imagery. The results showed an increase in soil salinity from 7.27% in the period 2005–2010 to 27.03% in 2015–2020, as well as an increase in vegetation from 10% to 24% in the same period. Also the strong inverse correlation between the NDVI and the SI showed that vegetation is significantly affected and directly influenced by soil salinity changes

Opis:
Along with sea-level rise, one of the most detrimental effects of climate change, is salinity leakage, which significantly affects agricultural activities throughout most of the world. This occurrence is becoming increasingly dangerous. The purpose of this study was to use Geographical Information Systems (GIS) to assess the current situation of agricultural lands in the province of Al-Diwaniyah, by employing GIS to document the salt-affected sites and arrive at the most important criteria affecting those lands as well as build an application model for suitability to clarify the affected sites and come up with paper and digital maps. To accomplish this, the study relied on the available data by extrapolating and analyzing remote sensing images using salt equations to analyze the Landsat 8 satellite images, after which these data were subjected to spatial statistical treatment in ArcGIS software. Moreover, 20 samples were taken from ground sampling points and subjected to laboratory analysis to compare and document the results. The research resulted in the creation of an up-to-date database for the locations of salt ratio growth or decrease in the province of Al-Diwaniyah, which can be relied on, starting from and expanding in the future. Land maps, both paper and digital, have been created and can be used and inferred. The findings demonstrated the model’s ability to steadily discriminate among all salinity groups while maintaining consistency with the ground truth data. Each of the four major salinity categories was highlighted. The best-performing indicators were used to build the MLR model, which was then used to anticipate soil salinity. The salt levels may be determined by the MLR combining NDVI and SI-5 with a high correlation value (R2 = 75.29%). Finally, it is shown that by combining spectral indicators with field measurements, it is possible to chart and forecast soil salinity on a large scale.

Opis:
The use of sewage sludge in agriculture is known to be environmentally friendly as it is a practical way of recycling municipal waste. A short-term experiment was carried out to study the changes in soil chemical and microbiological properties influenced through the addition of sewage sludge along with saline irrigation under a pearl millet-wheat crop rotation. There were three irrigation (canal water (0.35 dS m-1), 8 and 10 dS m-1 electrical conductivity saline water) and five fertilizer treatments (control-F1, sewage sludge (5 t ha-1)-F2, sewage sludge (5 t ha-1) +50% recommended dose of fertilizer (RDF)-F3, sewage sludge (5 t ha-1)+75% RDF-F4 and RDF-F5). The results showed that soil organic carbon, and available nitrogen, and phosphorus were reduced significantly under saline conditions but there was an increase in available potassium with the increasing salinity levels of the irrigation water. A significant reduction in soil microbial biomass carbon and enzyme activities was caused by 8 and 10 dS m-1 as compared to 0.35 dS m-1 at different growth stages of crops. Treatment F4 attained the highest soil microbial activity at each crop growth stage by a significant margin among all of the fertilizer treatments, which is associated with a substantial build-up of organic carbon and available NPK in the soil. Soil microbial activities followed a particular trend: at 35 and 75 days after sowing>harvest>sowing in pearl millet and wheat, respectively. Sewage sludge dumping is a major problem in India, and the present study suggests that by applying sewage sludge, soil biological health is improved; therefore its use in agriculture is recommended to farmers.

Opis:
Salinity occurring in intensively used agricultural, industrialized, and urbanized areas is one of the main factors in soil degradation. The effect of silver nanoparticles (AgNPs) on plant growth under environmental stresses is still not fully understood. Two experiments were conducted on the response of Asiatic lilies to treatment with colloidal AgNPs. In Experiment I, the study aimed to evaluate the effect of treating 'Osasco' lily bulbs with colloidal AgNPs (0, 25, 50, 100, and 150 ppm) on growth, flowering, and bulb yield, as well as the production of bulblets. Compared with the control, the applied colloidal AgNPs at all concentrations caused an acceleration of flowering and an increase in bulb diameter and the fresh weight of the aboveground part of the plants and bulbs. In addition, treatment with colloidal AgNPs at concentrations of 100 and 150 ppm increased bulblets’ number and fresh weight. In Experiment II, the effects of colloidal AgNPs (100 ppm) and NaCl stress (600 mM) on the growth parameters, assimilation pigment content, and chemical composition of 'Bright Pixi' lily leaves were evaluated. As a result of the application of colloidal AgNPs, plants flowered faster and had increased height, petal width, fresh bulb weight, bulb diameter, and several scales in the bulb. Under NaCl stress, plants had reduced fresh weight of the aboveground part and bulb, bulb diameter, number of scales in a bulb, and contents of assimilation pigments, N, K, Ca, Cu, Mn and Zn. Colloidal AgNPs offset the adverse effects of salinity on bulb yield by increasing fresh bulb, bulb diameter, and the number of scales in lily bulbs. In conclusion, using colloidal AgNPs can contribute to developing new methods of bulbous plants production and an effective strategy to protect plants from ever-increasing land salinization.

Opis:
Passive weathering in a field is a popular method of Spent Mushroom Substrate disposal. During this process rain and snowmelt water percolates through SMS piles and a large amount of solutes is leached out. Leachate contains substantially high concentrations of inorganic salts, that contribute to soil and groundwater salinity. In order to examine to what extent salts are leached from SMS piles, laboratory-scale lysimeter study was carried out. It was performed on two SMS substrates stored in the field for 3 years (substrate “A”) and 1 year (substrate “B”) respectively. Leaching experiment was conducted for 21 days, simulating annual rainfall cycles in Poland. Effluents were controlled for changes in chemical composition. Analysis included: moisture, pH, conductivity (EC), ions concentrations: Cl−, NO3−, SO2-4 , K+, Na+, Ca2+, Mg2+, Fe3+, Mn2+, Zn2+, total carbon (TC) and total nitrogen (TN) measurements. Leachate composition was dominated by Na+, K+, Ca2+, Mg2+, Cl− and SO2-4 concentrations. To describe the leaching dynamics seven mathematical models were fitted to the data. For the majority of components the function that best illustrated weathering process was a quadratic function, although Ca2+ leaching was best illustrated by a power function and Cl− release by a logarithmic one. After three weeks the quantity of inorganic salts eluted from 1 kgdw of SMS reached 16.8 g for substrate “A” and 43.9 g for substrate “B”. Obtained results indicate that improper management of SMS may result in excessive soil salinity.
Leżakowanie na polu jest popularną metodą zagospodarowania zużytego odpadu popieczarkowego (Spent Mushroom Substrate). W trakcie tego procesu wody opadowe oraz roztopowe przenikają przez pryzmy SMS i przyczyniają się do powstawania odcieków zawierających wysokie stężenia soli nieorganicznych, powodujących zasolenie środowiska wodno-gruntowego. W celu zbadania, w jakim stopniu składniki mineralne są wymywane ze zużytego odpadu popieczarkowego, przeprowadzono lizymetryczne badania laboratoryjne. Do badań użyto dwóch odpadów SMS, substratu „A” leżakującego przez 3 lata oraz substratu „B” składowanego w warunkach polowych przez rok. Eksperyment prowadzono przez 21 dni, symulując warunki wymywania, typowe dla opadów na terenie Polski. Zakres analiz obejmował następujące oznaczenia: wilgotność, pH, przewodnictwo właściwe (EC) oraz stężenia: Cl−, NO3−, SO2-4, K+, Na+, Ca2+, Mg2+, Fe3+, Mn2+, Zn2+, węgla całkowitego (TC) i azotu całkowitego (TN). Skład odcieku był zdominowany przez jony: Na+, K+, Ca2+, Mg2+, Cl− i SO2-4. Do opisu dynamiki wymywania tych składników użyto siedmiu modeli matematycznych. Dla większości składników przebieg wymywania najlepiej ilustrował model funkcji kwadratowej, w przypadku potasu funkcja potęgowa, a w przypadku chlorków funkcja logarytmiczna. Na podstawie krzywych wymywania stwierdzono, że po trzech tygodniach prowadzenia procesu ilość soli nieorganicznych wypłukana z 1 kg zużytego podłoża wynosiła w przypadku substratu „A” 16,8 g, a w przypadku substratu „B” 43,9 g. Uzyskane wyniki wskazują, że niewłaściwy sposób zagospodarowania zużytego podłoża z produkcji pieczarek może być przyczyną nadmiernego zasolenia gleby.

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:
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:
Three pot experiments were performed on cucumber, maize, soybean and wheat plants to investigate the effects of various substrate types, namely pumice, arenosol and chernozem soil (Exp. 1), of substrate salinity (Exp. 2) and of soil water content (SWC; Exp. 3) on the electrical capacitance measured in root-soil systems. The data were evaluated according to the basic principle of the two-dielectric capacitor model. Statistical analysis indicated that the capacitance measured in root-soil systems was determined by the capacitance of the root system for each combination of plant species and substrate. Furthermore, the results showed that substrate impedance had a negligible influence on the capacitance measured in root-soil systems. Substrate salinity had no direct effect on capacitance measured in root-soil systems, but salt-induced physicochemical changes in plant tissues could have influenced its dielectric properties. Capacitance measured in rootsoil systems increased exponentially with soil water content (it ranged from 10 to 48 v/v %), indicating that the measured capacitance was more sensitive to variability in moisture content at high rather than at low water saturation levels. This is not consistent with the general consensus that the capacitance method is unreliable in dry soil and should be used at soil water content close to field capacity. The present results will contribute to the more effective application of the root capacitance technique.

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.

Opis:
Omówiono rolę i znaczenie bakterii ryzosferowych stymulujących wzrost i rozwój roślin (PGPR) w glebach zdegradowanych na skutek ich zasolenia. Zanieczyszczenie gleb, będące przyczyną tzw. stresu solnego, może być spowodowane nadmiernym stosowaniem nawozów mineralnych i środków ochrony roślin. W przeprowadzonych badaniach wykazano, że szczepy bakterii Bacillus sp. i Variovorax sp. mogą stymulować wzrost rzepaku w środowisku zasolonym. Ponadto sprawdzono wpływ procesu liofilizacji, czasu i temperatury przechowywania liofilizatów bakteryjnych na przeżywalność sześciu szczepów – Bacillus sp., Bacteroidetes bacterium, Massilia sp., Pseudomonas fluorescens i Variovorax sp. Wykazano, że zarówno liofilizacja oraz wzrost temperatury, jak i czas przechowywania liofilizatów istotnie zmniejsza przeżywalność bakterii ryzosferowych. Stwierdzono, że przeżywalność bakterii stymulujących wzrost roślin w liofilizatach zależy od rodzaju szczepu bakteryjnego. Wszystkie liofilizowane mikroorganizmy wykazywały najwyższą przeżywalność po ich przechowywaniu w temperaturze 4°C. Potencjalnie zliofilizowane bakterie glebowe mogą być wykorzystane jako składniki biopreparatów w celu wspomagania wzrostu roślin na glebach nadmiernie zasolonych.
The role and significance of plant growth promoting rhizobacteria (PGPR) in soil degradation due to salinization was discussed. Soil pollution, leading to the so-called salt stress, may be caused by excessive use of mineral fertilizers and plant protection products. The study demonstrated the potential of Bacillus sp. and Variovorax sp. to enhance the rapeseed growth in the saline environment. Impact of lyophilization process, its time and the temperature of bacterial lyophilizate storage on survival of the six strains: Bacillus sp., Bacteroidetes bacterium, Massilia sp., Pseudomonas fluorescens and Variovorax sp. was examined. It was demonstrated that both lyophilization and an increase in temperature as well as lyophylizate storage time significantly reduced viability of rhizospheric microorganisms. Further, the survival rate of plant growth stimulating bacteria in lyophilisates depended on the bacterial strain. All the lyophilized microorganisms exhibited the best survival rate following storage at 4°C. The freeze-dried soil bacteria can potentially be used as components of bioproducts in order to assist plant growth in excessively saline soils.

To guarantee food security and job creation of small scale farmers to commercial farmers, unproductive farms in the South 24 PGS, West Bengal need land reform program to be restructured and evaluated for agricultural productivity. This study established a potential role of remote sensing and GIS for identification and mapping of salinity zone and spatial planning of agricultural land over the Basanti and Gosaba Islands(808.314sq. km) of South 24 PGS. District of West Bengal. The primary data i.e. soil pH, Electrical Conductivity (EC) and Sodium Absorption ratio (SAR) were obtained from soil samples of various GCP (Ground Control Points) locations collected at 50 mts. intervals by handheld GPS from 0–100 cm depths. The secondary information is acquired from the remotely sensed satellite data (LANDSAT ETM+) in different time scale and digital elevation model. The collected field samples were tested in the laboratory and were validated with Remote Sensing based digital indices analysisover the temporal satellite data to assess the potential changes due to over salinization. Soil physical properties such as texture, structure, depth and drainage condition is stored as attributes in a geographical soil database and linked with the soil map units. The thematic maps are integrated with climatic and terrain conditions of the area to produce land capability maps for paddy. Finally, The weighted overlay analysis was performed to assign theweights according to the importance of parameters taken into account for salineareaidentification and mapping to segregate higher, moderate, lower salinity zonesover the study area.
