To evaluate the effects of nanoparticle-based soil amendments on plant growth and phytostabilization.
Investigated effects of nano-sized stilbite-zeolite and nanoblack-carbon on durum-wheat.
Evaluated NSZ particle sizes (0.2 mm, 0.1 mm, <0.05 mm) and application rates (0%, 4%, 8% w/w).
Assessed NBC application rates (0%, 4%, 8% w/w).
Determined soil health improvements and metal uptake reductions in grains.
Optimal treatment of NSZ (<0.05 mm) and NBC at 8% increased grain yield by 140.5%.
Soil CEC improved by 20.04%, and available phosphorus increased by over 300%.
Grain yields rose from 1,057 kg ha-1 to 2,544 kg ha-1.
Cd and Hg concentrations in grains were reduced by 69.7% and 69.1%, respectively.
As and Pb levels decreased by 55.8% and 42.1% with NBC treatment.

Resumen

Nanoparticle-based soil amendments represent a promising strategy to improve plant growth and phytostabilization in contaminated soils. This study investigated the efficacy of nano-sized stilbite-zeolite (NSZ) and nanoblack-carbon (NBC) on durum-wheat (Triticum turgidum L.). This study was conducted to evaluate the effects of NSZ particle size (0.2 mm, 0.1 mm, -1 in the control to 2,544 kg ha-1, representing a 140.5% improvement. The number of grains per spike increased from 22.33 to 34.3, while the amendments effectively reduced heavy metal uptake. Specific treatments, such as NSZ at 4% (w/w) (NSZ2), significantly reduced Cd and Hg concentrations in grain by 69.7% and 69.1%, respectively, compared to the control. The NBC treatment at 8% (w/w) (NBC2) reduced As and Pb levels by 55.8% and 42.1%. These reductions confirm successful immobilization of metals in the soil and restricted translocation to edible grains.
