Buckwheat is an unusually fast-growing crop with a variety of uses. Its flexibility and wide adaptation led Buckwheat Extract to be grown on more than a million acres in China in the late 1800s. Most buckwheat is ground into flour and used for a variety of foods.
Buckwheat has also been used widely as a cover crop to smother weeds and improve the soil. The crop seems to improve soil tilth and is reported to make phosphorous more available as a soil nutrient, possible through root-associated mycorrhizae. Buckwheat flowers profusely, making Buckwheat Extract popular with beekeepers and an attractive crop in the landscape.
