The uptake of Arsenic species by commonly grown Australian rice varieties cultivated utilising two widely used agronomic practices (straw incorporation and nitrogen fertilisation) and the role dimethyl arsenic plays in inducing straighthead disease

Abstract

Rice is inherently efficient at accumulating arsenic (As) due to it being grown under anaerobic conditions. Arsenic in rice plants can pose a significant risk to human health. In this study we aim to determine if two agronomic practices, i.e. straw and nitrogen addition to rice paddies, influence the bioavailability of different As species within the soil and their incorporation in the various components of the rice plant and whether these practices lead to straighthead disease.
