Small understory trees increase growth following sustained drought in the Amazon. [PDF]

New Phytol
Summary Droughts pose a major threat to the Amazon rainforest, yet the mechanisms enabling trees to maintain growth under prolonged drought remain poorly understood, particularly in the understory layer. We leveraged a 22‐yr Throughfall Exclusion (TFE) in a 1‐ha plot in eastern Amazonia, paired with a Control plot, to test whether small understory ...

Foliar absorption of nutrients: II [PDF]

Soil Science and Plant Nutrition, 1960
It has been hitherto indicated that the translocation of phosphorus has the biochemical response with carbohydrates in the plant. From that point of view, many workers have shown the variable effects of sucrose on the absorption and translocation of foliar applied phosphoric acid. Yatazawa et al.

Nocturnal Transpiration May Be Associated with Foliar Nutrient Uptake

Plants, 2023
Aerosols can contribute to plant nutrition via foliar uptake. The conditions for this are best at night because the humidity is high and hygroscopic, saline deposits can deliquesce as a result. Still, stomata tend to be closed at night to avoid unproductive water loss. However, if needed, nutrients are on the leaf surface, and plants could benefit from
