UDaily: New UD study looks at adding rice residue to lower arsenic, improve crop yields

A new study by University of Delaware researchers considers how adding silica-rich rice residue -- such as husks, straw and the ash of those materials -- to improve crop yields and decrease arsenic uptake may affect the soils in which rice plants are grown. 

The results of the study were recently published in Plant and Soil, an international journal on plant-soil relationships. 

The study was carried out by Evanise Penido, a visiting student from the Federal University of Lavras (UFLA) in Brazil.
