Soil Systems, Journal Year: 2024, Volume and Issue: 8(1), P. 11 - 11

Published: Jan. 15, 2024

Soil salinity is a serious problem facing many countries globally, especially those with semi-arid and arid climates. can have negative influences on soil microbial activity as well chemical physical processes, all of which are crucial for health, fertility, productivity. negatively affect physiological, biochemical, genetic attributes cultivated plants well. Plants wide variety responses to stress classified sensitive (e.g., carrot strawberry), moderately (grapevine), tolerant (wheat) (barley date palm) depending the salt content required cause crop production problems. Salinity mitigation represents critical global agricultural issue. This review highlights properties classification salt-affected soils, plant damage from osmotic due salinity, possible approaches (i.e., applied nutrients, inoculations, organic amendments, physio-chemical approaches, biological nano-management), research gaps that important future food security. The strong relationship between different subdisciplines (mainly, biogeochemistry, microbiology, fertility nutrition) also discussed.

Additive-Mediated Phytoextraction of Copper-Contaminated Soils Using Medicago lupulina L.

Egyptian Journal of Soil Science, Journal Year: 2024, Volume and Issue: 64(2), P. 599 - 618

Published: Feb. 23, 2024

Phytoremediation is an acceptable, economical, and eco-friendly way to remediate metal-contaminated soils, especially in areas near industrial zones. Copper (Cu) industries generate effluent that contains various Cu pollutants. Discharging these pollutants into the environment can adversely impact soil biota through food chain. In this study, researchers used Medicago lupulina for phytoremediation samples collected from area surrounding zangezur copper molybdenum combine (ZCMC) plant southeast Armenia. The experiment was conducted ex-situ pots, concentration of heavy metals analyzed before after applying using different additives, including ammonium nitrate, citric acid, malic EDTA. results showed additives increased phytoextraction process while also improving biomass, root growth, chlorophyll content M. lupulina. With bioconcentration factor (BCFroot)>1 translocation (TF)>1 values, be considered a good hyperaccumulator with better capacity metal.

Nanomaterials–plants–microbes interaction: plant growth promotion and stress mitigation

Frontiers in Microbiology, Journal Year: 2025, Volume and Issue: 15

Published: Jan. 15, 2025

Soil salinization, extreme climate conditions, and phytopathogens are abiotic biotic stressors that remarkably reduce agricultural productivity. Recently, nanomaterials have gained attention as effective agents for applications to mitigate such stresses. This review aims critically appraise the available literature on interactions involving nanomaterials, plants, microorganisms. explores role of in enhancing plant growth mitigating These materials can be synthesized by microbes, algae, they applied fertilizers stress amelioration agents. Nanomaterials facilitate nutrient uptake, improve water retention, enhance efficiency active ingredient delivery. strengthen antioxidant systems, regulate photosynthesis, stabilize hormonal pathways. Concurrently, their antimicrobial protective properties provide resilience against stressors, including pathogens pests, promoting immune responses optimizing microbial-plant symbiosis. The synergistic with beneficial microorganisms optimize under conditions. also serve carriers nutrients, regulators, pesticides, thus acting like "smart fertilizers. While nanotechnology offers great promise, addressing potential environmental ecotoxicological risks associated use is necessary. outlines pathways leveraging achieve resilient, sustainable, climate-smart systems integrating molecular insights practical applications.

Soil Degradation under a Changing Climate: Management from Traditional to Nano-Approaches

Egyptian Journal of Soil Science, Journal Year: 2023, Volume and Issue: 64(1), P. 0 - 0

Published: Dec. 11, 2023

In the era of climate change, soil and different compartments agroecosystem suffer from forms water degradation, which an urgent need for management is required. Under arid semi-arid countries, degradation are more severe causing a decline in agricultural productivity, food security. Increasing led to decrease quality, global insecurity, ecosystem health problem, then non-sustainable development. Several human activities have worsened especially under require proper methods management. With growing concerns on nanotechnology, can this science offer promising solutions/approaches engineer amendments overcome scarcity? What possible delving nanomaterials, their mechanisms protecting environment. This study focuses causes consequences, as well approaches including traditional, GIS remote sensing, nano-management degradation. The expected after intensive applications nanomaterials major further question urgently needed be answered. There also assess long-term environmental impacts nanoparticles, may potential leaching, accumulate potentially enter chain, many problems health.

Nano-NPK and Nano-Sulfur Boost Vegetative Growth and Chemical Constituents of African Mahogany (Khaya senegalensis L.) Seedlings under Saline Soil Conditions

Egyptian Journal of Soil Science, Journal Year: 2024, Volume and Issue: 64(2), P. 631 - 642

Published: Feb. 23, 2024

Soil salinity is considered a serious and limiting factor reducing the crop productivity in particular under arid, semi-arid conditions. Pot experiments were conducted at Ornamental Department of Horticulture Research Station Sakha, Kafr El-Sheikh Governorate, Egypt during season 2021 2022. This study aimed to evaluate effect foliar application with nano-NPK nano-sulfur using different doses on growth chemical compounds Khaya senegalensis L. stress.

Egyptian Journal of Soil Science, Journal Year: 2024, Volume and Issue: 64(2), P. 673 - 698

Published: March 9, 2024

Using chitosan/jojoba oil and oil/ZnO nanocomposite capsules, this study looked at how to get rid of Fe2+ Ni2+ ions from soil in areas with high levels heavy metals like ions, which pose environmental risks the ecosystem. The created adsorbents were characterized using scanning electron microscopy (SEM), Fourier transform infrared (FTIR), particle size measurements transmission (TEM). A batch experiment was performed determine effects contact time, adsorbate concentration, temperature, solution pH. At pH 3.3 5.3, composite materials demonstrated adsorption efficiencies 90% for 69.8% aqueous solutions. According isotherm investigations, polymer nanocomposites satisfy Langmuir Freundlich models. But model more accurately experimental data. results suggested that capsules serve as practical removing These can be utilized fertilizers, especially soils contaminated Fe Ni, while providing Mallow plant (Corchorus olitorius) nutrients Zn.
