The objective of this study was to evaluate the rate of foliar absorption of magnesium (Mg) salts with different deliquescence and efflorescence relative humidity values (DRH and ERH, also known as point of deliquescence (POD) and point of efflorescence (POE), respectively) when supplied to leaves of model plants with different wettability properties. For this purpose, a greenhouse pot experiment was conducted with lettuce (very wettable), broccoli (highly unwettable) and leek (highly unwettable). Foliar sprays contained 0.1% surfactant plus 100 mM Mg supplied as MgCl·6HO, Mg(NO)·6HO or MgSO·7HO. Leaf Mg concentrations were determined 1 and 7 days after foliar application. Anion concentrations were also measured in lettuce where a significant foliar Mg absorption was detected. Leaf wettability, leaf surface free energy and fertilizer drop deposit appearance onto the foliage were assessed. It is concluded that despite including a surfactant in the spray formulation, leaf wettability plays a major role in foliar Mg absorption.

Background And Aims: Nolana mollis is a dominant plant species in the hyperarid Atacama Desert. A previous hypothesis states that N. mollis owes its success to the condensation of atmospheric water from undersaturated air onto its leaf surfaces by exuded salts, and absorption of this water by its leaves, or by shallow roots following drip onto the soil surface; living roots of N.

The rising interest in foliar nutrient spraying as a strategy to boost crop yields has led to investigations of how such application influences nutrient uptake and accumulation, especially in edible plant parts. Despite its importance, the effects of single versus simultaneous nutrient application on plant absorption, transport, and accumulation have been underexplored. This study addresses this knowledge gap by examining the physiological and molecular responses of rice to foliar application of nitrogen (N) and zinc (Zn) individually and in combination at different growth stages.

Rice may absorb Cadmium (Cd) from the air through its leaves. The process of Cd foliar absorption, accumulation, and redistribution is yet unknown, nevertheless. In this study, the process of Cd absorption from rice leaves and its accumulation and redistribution during all stages of the rice plant's growth were examined.

Alkalinity is a significant environmental factor affecting crop production, which is exacerbated by the current climate change scenario. In alkaline soils, iron availability is severely reduced due to its low solubility at high pH levels and bicarbonate concentrations, which hinders plant iron absorption by rendering it inactive. In modern agriculture, green-synthesized nanoparticles have attracted considerable attention due to their environmental compatibility, cost-effectiveness, and enhanced potential for foliar uptake.
