Exploring the role of endogenous and exogenous silicon in reducing arsenic accumulation in rice: A multi-scale hydroponic to field study.

ABSTRACT:

Introduction

Traditionally, Silicon (Si) fertilizers are applied externally to the soil or sprayed on the leaves to reduce rice's arsenic (As) accumulation. However, in practical agricultural production, the economic benefits of lowering As in rice grains often fail to outweigh the production costs.

Objectives

This study investigated an innovative technology-Si-rich seedlings (endogenous Si)-that is simple to implement, cost-effective, and highly effective in reducing As accumulation in rice grains.

Methods

The effects of exogenous and endogenous Si supplementation on As dynamics in rice were investigated in hydroponics in field experiments.

Results

Both methods significantly reduced As accumulation in the rice grains (22.23 % and 17.70 %, respectively). There
