I present a meta‐analysis of plant responses to 48 nutrient addition experiments conducted
with native species in naturally growing tropical forests, exclusive of mangrove forests. The …

The productivity of rainforests growing on highly weathered tropical soils is expected to be
limited by phosphorus availability. Yet, controlled fertilization experiments have been unable …

Plants invest a considerable amount of leaf nitrogen in the photosynthetic enzyme ribulose-
1, 5-bisphosphate carboxylase-oxygenase (RuBisCO), forming a strong coupling of nitrogen …

Global terrestrial models currently predict that the Amazon rainforest will continue to act as a
carbon sink in the future, primarily owing to the rising atmospheric carbon dioxide (CO2) …

The soil nitrogen (N) and phosphorus (P) availability often constrains soil carbon (C) pool,
and elevated N deposition could further intensify soil P limitation, which may affect soil C …

Contemporary soil science and conservation methods of effective forestry Forests and the
soils that serve as their foundation cover almost a third of the world's land area. Soils …

Potassium (K+) is the most abundant inorganic cation in plant cells, playing a critical role in
various plant functions. However, the impacts of K on natural terrestrial ecosystems have …

Phosphorus (P) availability is a limiting factor for plant growth in tropical and subtropical
regions, but many tropical and subtropical forests maintain high levels of productivity and …

人类活动加剧了活性氮的生产和排放, 并导致氮沉降日益增加并全球化. 目前,
