Subsequently, the shards could perform several functions in the soil, including providing structure to slow erosion and compaction as well as possibly containing inoculations of mychorrizal fungi. lou Bladye,

This sort of pottery is usually impregnated with carbon and very porous. This could have been used to maintain proper moisture. If the soil were subject to too much moisture the shards could have been used like lateral tiles to drain water off between the soil and the substrate, which I am guessing has a high clay content. What do they know about the shards? I would like to know more about the pot shards. This sort of pottery is usually impregnated with carbon and very porous.
