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 ...

Analysis of Nutrients in Foliar Fertilizers

, 2021
The use of fertilizers is necessary to increase productivity, food quality and environmental and economic sustainability. Foliar fertilization is an extremely important tool, it is friendlier to the environment, with a more immediate and targeted response to the plant's nutrition objective when compared to soil fertilization.

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

FOLIAR NUTRIENT UPTAKE IN CRANBERRY [PDF]

HortScience, 1990
Foliar feeding of crop plants is an increasingly popular practice. The use of foliar nutrients relies on the ability of the plant to sorb nutrients through the leaves. Cranberries (Vaccinium macrocarpon Ait.) are known to have a waxy cuticle on the leaf surface which may impede nutrient uptake, leaving only the lower leaf surface for effective uptake ...
