Re: Rice hulls as soil amendment
WARNING!
I discovered something about rice hulls that needs further investigation. Apparently, rice hulls contain something that is phytotoxic that is worsened after rice hulls are milled to finer particles. I milled rice hulls in a food blender. The milled rice hulls contained a substantial amount of fine powder along with coarse particles. If you try this, wear a mask to avoid breathing dust. I mixed it with 2/3 screened peat moss to germinate tomato seeds. The resulting tomato seedlings were stunted and leaves browned around the edges.
