Our current understanding of silicon (Si) availability in agricultural soils is reviewed and
knowledge gaps are highlighted. Silicon is a beneficial rather than essential plant nutrient …

Adequate silicon fertilization greatly boosts rice yield and mitigates biotic and abiotic stress,
and improves grain quality through lowering the content of cadmium and inorganic arsenic …

Contamination of paddy soils with potentially toxic elements (PTEs) has become a severe
environmental issue. Application of functionalized biochar for rice cultivation has been …

Carbon sequestered in phytoliths, the silicified features of plants, may accumulate in soils
and sediments for several hundreds to thousands of years depending mainly on the …

Phytolith carbon (C) sequestration plays a key role in mitigating global climate change at a
centennial to millennial time scale. However, previous estimates of phytolith‐occluded …

Rice straw incorporation is labor-intensive and influences greenhouse gas emissions but
can increase soil organic carbon (C) and recycle nutrients. Rice straw contains about 80, 40 …

Abstract Background Silicon (Si) is increasingly recognized as a pivotal beneficial element
for plants in ecology and agricultural sciences, but soil-plant Si cycling has been considered …

Increasing plant-availability of Si through soil amendment of Si-rich rice residues can
decrease inorganic As without affecting Cd levels in grain under flooded soil conditions …

Phytoliths form in plant tissues as fine, silt-sized amorphous silica particles. Once deposited
in soils by plant debris, they can dissolve and feed silicon (Si) fluxes to the biosphere and …

Despite the global importance of As in rice, research has primarily focused on Bangladesh,
India, China, and the United States with limited attention given to other countries. Owing to …
