Journal of Ecology, Volume 112, Issue 4, Page 690-700, April 2024.The maintenance of highly productive lowland tropical forests on infertile soils is often attributed to nutrient cycling via litterfall. Almost 40 years after this theory was first proposed, our large‐scale field experiment demonstrates that tree growth and litter production decline in response to long‐term litter removal, providing the first empirical
