Impact of Cadmium-contaminated water and irrigation levels on microbiological properties of soils with different textures

EURASIAN JOURNAL OF SOIL SCIENCE (EJSS), Journal Year: 2025, Volume and Issue: 14(2), P. 107 - 115

Cadmium (Cd) contamination poses a significant threat to soil health and agricultural productivity, particularly under varying water availability textures. This study examines the effects of levels (25%, 50%, 75%, 100% field capacity) textures (sandy clay loam, silty clay) on key microbiological properties, including basal respiration (BSR), microbial biomass carbon (Cmic), dehydrogenase activity (DHA), catalase (CA), in Cd-contaminated soils. An incubation experiment was conducted controlled conditions at 20 ± 0.5°C for 10 days. Microbiological properties were assessed using standard methods: alkali absorption BSR, substrate-induced Cmic, spectrophotometric assays DHA, volumetric determination CA. Optimal across all parameters observed 75% capacity, highlighting importance balanced moisture. Clay soils consistently exhibited highest due their superior organic matter content buffering while sandy loam showed lowest limited retention nutrient availability. Excessive moisture capacity reduced oxygen diffusion, suppressing activity, insufficient 25% constrained metabolism. These findings provide critical insights into interplay between texture, availability, Cd contamination, offering valuable guidance sustainable management practices mitigate heavy metal toxicity systems.

Impact of petroleum contamination on soil properties in Absheron Peninsula, Azerbaijan

EURASIAN JOURNAL OF SOIL SCIENCE (EJSS), Journal Year: 2024, Volume and Issue: 13(4), P. 358 - 365

Published: Sept. 30, 2024

This study aims to assess the extent of hydrocarbon and heavy metal contamination in soils from specific areas on Azerbaijan's Absheron Peninsula, including Absheron, Suraxanı, Baku, evaluate impact this soil properties. Soil samples were analyzed for Total Petroleum Hydrocarbons (TPH) metals, aluminum, arsenic, cadmium, lead, iron, alongside assessments physical, chemical biological The results revealed significant across all studied areas, particularly where TPH levels reached 190 ± 20 mg/kg, exceeding environmental standard 100 mg/kg. Similarly, Suraxanı exhibited alarmingly high concentrations with aluminum at 30,128 1,500 arsenic 50.94 2.5 cadmium 0.153 0.01 surpassing acceptable limits. These contaminants severely degraded health, evidenced by increased bulk density (1.7 g/cm³ Suraxanı) reduced porosity. Microbial activity, a key indicator fertility, was also markedly lower contaminated regions, total bacterial count being less than half that uncontaminated area. findings underscore urgent need comprehensive management practices stricter regulations mitigate contamination's adverse effects protect both ecosystems public health Azerbaijan’s petroleum areas.

Sustainable agriculture through qanat systems in Karabakh: Water and soil characteristics in the context of climate change

EURASIAN JOURNAL OF SOIL SCIENCE (EJSS), Journal Year: 2024, Volume and Issue: 13(4), P. 303 - 311

Published: Sept. 30, 2024

This study investigates the water quality and soil characteristics associated with qanat systems in Cebrail district of Karabakh region, Azerbaijan. Qanat systems, traditional underground channels designed for transport, play a crucial role providing reliable sources drinking irrigation. Water samples were collected from seven analyzed various physicochemical properties. parameters included pH, electrical conductivity, hardness, mineralization, concentrations calcium, magnesium, sodium, other ions. Soil analyses focused on organic matter content, salinization degree, presence key ions like sulfate nitrate. The results indicated that is generally high quality, pH levels suitable both However, some exhibited conductivity mineralization levels, suggesting potential salinity issues sensitive crops. showed favorable conditions agriculture, good low salinity, content. analysis revealed significant interaction between characteristics, emphasizing importance integrated management practices. In context climate change, sustainability critical. Recommendations include regular monitoring amendments to mitigate efficient irrigation techniques, use climate-resilient infrastructure. underscores arid semi-arid regions provides practical recommendations sustainable land resource management, enhancing socio-economic well-being local communities.
