Shaver and Chapin (1986) pointed out that though the tundra ecosystems they studied consistently increased primary production in response to fertilization, individual species and growth forms showed m...
See AnswerQ: Field experiments demonstrate that variation in soil fertility influences terrestrial primary production
Field experiments demonstrate that variation in soil fertility influences terrestrial primary production. However, we cannot say that nutrients exert primary control. That role is still attributed to...
