Diverse tropical forests grow fast despite widespread phosphorus limitation

Diverse tropical forests grow fast despite widespread phosphorus limitation Ecological theory says that poor soils limit the productivity of tropical forests, but adding nutrients as fertilizer rarely increases tree growth, suggesting that productivity is not limited by nutrients after all. Researchers resolved this apparent contradiction, showing that phosphorus limits the growth of individual tree species but not entire forest communities. Their results have sweeping implications for understanding forest growth and change. http://ift.tt/eA8V8J
