Knochenzemente für die EndoprothetikNitrogen is quite often a growth-limiting factor in both temperate and boreal forests, as is shown by the usually rapid response of trees to nitrogen fertilization. The total amount of nitrogen in most forest soils, however, is quite high. The limiting factor usually is not the amount of nitrogen but its availability to the trees.
