Supplementing plants with silicon (Si) often improves plant productivity and resilience to biotic abiotic stresses, but this is mostly reported in highly controlled experimental environments. The ecological consequences of Si supplementation, including environmental benefits potential risks, are therefore poorly understood require field-scale evaluation how supplementation affects the wider ecosystem, such as invertebrate communities soil physicochemical properties. We conducted first field assessment a legume (lucerne; Medicago sativa) agroecosystem its associated responded two levels (calcium silicate slag), over years. quantified seasonal changes abundance diversity aboveground arthropod communities, crop yield, elemental nutritional chemistry, pH well chemistry. highest rate increased bioavailable by 181% from 5.2 6.3, relative untreated plots, significant positive correlation between pH. led an increase yield up 52%; however, magnitude varied season.

Ameliorative Effects of Silica on Growth, Antioxidant Response, and Metal Uptake in Chromium-Exposed Wheat

Deleted Journal, Journal Year: 2025, Volume and Issue: 77(1)

Published: Jan. 13, 2025

Chromium (Cr) toxicity adversely affects crop productivity and poses significantly health risks. However, silicon (Si), an inorganic amendment, has potential to mitigate these effects in wheat crop. A pot study was conducted examine the ameliorative role of Si enhancing grain yield, reducing metal accumulation improving overall performance by influencing morphological, physiological biochemical parameters under Cr stress. The experiment followed a completely randomized design with four replications. pots were irrigated weekly contaminated water after germination, two levels (Si at 50 mg kg−1 100 kg−1) applied. stress reduced growth; however, application both silica stressed plants improved growth attributes. addition led significant increase plant height (up 11%), root shoot biomass, fresh biomass increased 60 70%, dry 47 162%, respectively. Root morphological up 100%, membrane stability 67%. Additionally, modulated antioxidant enzymatic activity, which provided protection against Silicon also concentration tissues 35%. Daily intake Health Risk Index lowered application. Overall, exogenous phytoaccumulation, thereby lowering risks promoting development.

Could large‐scale silicon supplementation of crop‐lands mitigate the impacts of climate change?

Plants People Planet, Journal Year: 2025, Volume and Issue: unknown

Published: April 21, 2025

Societal Impact Statement Intervention strategies that involve supplementing crop‐lands with silicon have significant scope for carbon capture and drought mitigation, offering wide‐ranging societal impacts. These include contributing to decarbonisation goals, enhancing food security, providing economic benefits reducing environmental damage associated intensive agronomic practices. This article highlights emerging evidence suggests elevated atmospheric CO 2 water limitation may impair accumulation in plants. While this does not negate the outlined benefits, we argue these limitations must be thoroughly quantified incorporated into large‐scale implementation plans ensure reliability effectiveness of intervention strategies. Summary Silicon plants is increasingly recognised as playing an important functional role alleviating stresses. Most research date has focussed on relieving stresses crops, including pest pathogen damage, soil salinity drought. Recently, attention turned application agricultural landscapes a potential anthropogenic climate change mitigation strategy. includes fertilisation enhance storage through advanced weathering silicates, or by incorporating phytoliths plant tissues. geoengineering approaches potential, they could also present challenges. explores opportunities silicon‐based interventions mitigating impacts rising dioxide levels increased incidences We despite promise supplementation stress under change, paradoxically shows very conditions can significantly impede propose framework guide development mitigate questions should addressed their future conditions.

Integrated physiological, transcriptomic, and metabolomic analyses of drought stress alleviation in Ehretia macrophylla Wall. seedlings by SiO2 NPs (silica nanoparticles)

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 15

Published: Feb. 2, 2024

With environmental problems such as climate global warming, drought has become one of the major stress factors, because it severely affects plant growth and development. Silicon dioxide nanoparticles (SiO 2 NPs) are crucial for mitigating abiotic stresses suffered by plants in unfavorable conditions further promoting growth, drought. This study aimed to investigate effect different concentrations SiO NPs on Ehretia macrophylla Wall. seedlings under severe (water content soil, 30–35%). The treatment was started starting spraying SiO2 macrophyla, which were consistently normal (soil moisture 30-35%), respectively, at seedling stage, followed physiological biochemical measurements, transcriptomics metabolomics analyses. (100 mg·L −1 ) reduced malondialdehyde hydrogen peroxide enhanced activity antioxidant enzymes stress. Transcriptomic analysis showed that 1451 differentially expressed genes (DEGs) leaves E . regulated stress, these mainly participate auxin signal transduction mitogen-activated protein kinase signaling pathways. also found metabolism fatty acids α-linolenic may play a key role enhancement tolerance NP-treated E. seedlings. Metabolomics studies indicated accumulation level secondary metabolites related higher after treatment. revealed insights into mechanisms induced enhancing plants.

Elevated leaf silicon (Si) concentrations improve drought resistance in cultivated plants, suggesting Si might also performance of wild species. Tropical tree species, for instance, take up substantial amounts Si, and varies markedly at local regional scales, consequences seedling resistance. Yet, whether elevated improves tropical forests is unknown. To manipulate concentrations, seedlings seven species were grown Si-rich -poor soil, before exposing them to the forest understorey. Survival, growth wilting monitored. did not survival any In one was reduced previously contrary our expectation.
