South Korean scientists said Tuesday that they have developed an eco-friendly topsoil that enhances plant growth and drastically reduces harmful residues of pesticides.
A research team led by Chung Byung-yeoup at the Korea Atomic Energy Research Institute (KAERI) said the new soil is made by using small quantities of so-called rare earth elements. These are a group of compound materials made up of Lanthan, Scandium and Yterium.
"Test have shown that this new topsoil boosts plant growth by 30 per cent, strengthens roots, while lowering nitrate and pesticide levels by up to 60 per cent.
There\’s another name for Lanthanum, Yttrium and the like: heavy metals. Serioulsy, most surprised that anyone is recommending adding these to topsoil.
