What’s a Seed ball?

Seeds balls are an ancient technique for propagating plants from seeds without opening up soil with cultivation tools such as a plow.

The rediscovery and popularization of seedballs (or “Clay Dumplings” as he called them) in modern times is typically ascribed to Japanese natural farmer and philosopher Masanobu Fukuoka.

As with many natural farmers, Fukuoka believed that tillage over large areas is laborious, destructive to soil health, and ultimately not needed and thus a waste of time and energy. Thus, seedballs have become an important aspect of many natural farming and conservation enterprises around the world.
