Potato Growth Responses in Arcillite and Sand1

Abstract
Root and plant growth and tuber development of potato (Solanum tuberosum L.) were considerably better in arcillite than in white quartz sand. Arcillite has several advantages for root and tuber studies requiring minimal damage to the tissue and/or adherence of the media to the root System. Mineral element analysis indicated that various nutrients including boron in arcillite became slowly available for plant growth.
