Once root growth slows down, the supply of water and minerals to the tree is diminished. Lack of root growth and consequent decreases in water uptake lead to water stress in the shoots, thereby reducing photosynthesis but increasing respiration. Decreased nitrification and eventual loss of nitrogen to the tree reduce vigor and growth and may eventually kill it.
