Ethylene-free biochar for plant nurseries

Greenhouse plant nurseries commonly use vermiculite and peat moss for potting plants, thus threatening natural resources of vermiculite and peat moss. They can be replaced by biochar, which is a cheap product of organic wastes. However fresh biochar emits ethylene, a gas that has adverse effects on plant at high levels because ethylene is a plant hormone. Fulton et al. found a simple solution to get rid of ethylene emission.
