When the blood supply to the bone is blocked, the area without blood supply can die. This may lead to collapse of the bone requiring replacement with an artificial hip joint.
Nitrogen Fixing Trees for Permaculture Flowers of the leguminous tree, Kowhai, the national flower of New Zealand Nitrogen fixation is a pattern of nutrient cycling which has successfully been used in perennial agriculture for millennia. This article focuses on legumes, which are nitrogen fixers [â¦]
To transform nitrogen into a better food for plants, bacteria fix it.
