> All these buckwheat questions!  I had to see what my husband's old (1967) book Principles of Field Crop Production says.  I have also heard that buckwheat is good at bringing up phosphorus.  A few quotes:

>     Injurious effects of buckwheat on subsequent crops on unfertilized land are attributed to excessive removal of mineral plant foods by the rapidly growing, shallow-feeding buckwheat plants. (p. 744)

> My guess is that these injurious effects would happen only if the buckwheat crop were removed from the field, not if it were incorporated into the soil or left on the surface.
