arg clay
"Although clay soils cannot be made ideal, they can be improved by any treatment which will cause the particles to form small granules and crumbs. The best treatment for this purpose is to incorporate large amounts of organic matter into the soil to promote better soil structure. The improved condition may remain long after organic matter has disappeared."
