Plant scientists usually classify plant mineral nutrients based on the concept of “essentiality” defined by Arnon and Stout as those elements necessary to complete the life cycle of a plant. Certain other elements such as Na have a ubiquitous presence in soils and waters and are widely taken up and utilized by plants, but are not considered as plant nutrients because they do not meet the strict definition of “essentiality.” Sodium has a very specific function in the concentration of carbon… Expand
Comparison of nutrient concentrations in leaves of five plants
TLDR
Investigation on bioaccumulation of mineral elements and identification of plants based on the concentrations of the elements in the plant leaves found that for all plants high concentrations of potassium, sodium, phosphorus and magnesium were typical, while concentrations of zinc and copper were the lowest.

Potassium Substitution by Sodium in Plants
TLDR
The question of K+ substitution by Na+ in plant physiology is not only of academic interest but has considerable practical implications in relation to fertilizer management and plant growth in salt-affected environments. Expand
Sodium replacement of potassium in physiological processes of olive trees (var. Barnea) as affected by drought.
Potassium (K) is a macro-nutrient understood to play a role in the physiological performance of plants under drought. In some plant species, sodium (Na) can partially substitute K. Although aExpand
Compositional nutrient diagnosis in sugar beet with sodium supplementation
ABSTRACT A plant stress is related both to deficiency of a particular nutrient and to inadequate relationships between nutrients. The objective of the study was to assess the sugar beet nutritionalExpand
Regulatory Role of Mineral Elements in the Metabolism of Medicinal Plants
Minerals have a diversified role in medicinal plant metabolism. Severity or scarcity of these causes multifarious effects in plant metabolism. Each and every aspect of plant biochemistry, physiology,Expand
Plant Growth Promoting Bacteria Play a Major Role in Nutrient Uptake of Cowpea Plants
Plant growth promoting bacteria including Agrobacterium spp., Azotobacter spp., Pseudomonas sp. and Paenibacillus sp., which are known to promote the growth of plants were coinoculated co-inoculatedExpand
Sodium-potassium synergism in Theobroma cacao: stimulation of photosynthesis, water-use efficiency and mineral nutrition.
TLDR
It is shown that Na(+) can partially replace K(+) in the nutrition of clonal cacao, with significant beneficial effects on photosynthesis, WUE and mineral nutrition in this major perennial C3 crop. Expand
Effects of Salinity Stress on Chloroplast Structure and Function
Salinity is a growing problem affecting soils and agriculture in many parts of the world. The presence of salt in plant cells disrupts many basic metabolic processes, contributing to severe negativeExpand
Potassium–sodium interactions in soil and plant under saline-sodic conditions†
About 7% of the total land around the globe is salt-affected causing a great loss to agriculture. Salt stress refers to the excessive amount of soluble salts in the root zone which induce osmoticExpand
The ideal percentage of K substitution by Na in Eucalyptus seedlings: Evidences from leaf carbon isotopic composition, leaf gas exchanges and plant growth.
TLDR
Substitution of 25% of K by Na provided significant gains in nutritional status and positive plant physiological responses by increasing WUE, stomatal diffusion, and by augmenting CO2 uptake efficiency in Eucalyptus seedlings. Expand

Sodium and Silicon as Nutrients for the Tomato Plant.
TLDR
The increasing availability of polyethylene ware, coupled with the increasing purity of the salts available from the chemical supply houses, has provided means by which the study of the possible essentiality of these three elements has been made practical. Expand
Role of Mineral Elements with Emphasis on the Univalent Cations
TLDR
The status of the knowledge of the roles of the essential mineral elements other than univalent cations is surveyed, referring for the most part to the pertinent recent reviews, and the importance of these cations in this capacity is questionable. Expand
Feasibility of substituting sodium for potassium in crop plants for advanced life support systems.
TLDR
Results to date suggest that Na concentrations up to 100 g kg-1 dry weight may be achievable in the edible portions of Na-tolerant crops, and a flow path for nutrient solution high in Na wastes has been suggested for optimizing Na and nitrogen incorporation and utilization from such solutions. Expand
Recycling of Na in advanced life support: strategies based on crop production systems.
TLDR
Various strategies are outlined that include both genetic and environmental management aspects to optimize the Na recovery from waste streams and their resupply through the human diet in ALS. Expand
THE ESSENTIALITY OF CERTAIN ELEMENTS IN MINUTE QUANTITY FOR PLANTS WITH SPECIAL REFERENCE TO COPPER.
TLDR
Conclusive proof of the indispensability of the so-called microelements, that is, elements required in minute amounts by plants, can be obtained by the use of artificial culture media (the water culture technique was used in this investigation), provided special procedures are employed to remove incidental impurities. Expand
Sodium and rubidium as possible nutrients for sugar beet plants.
TLDR
Essentiality of either Na and/or Rb per se for growth of sugar beets may be inferred, but other criteria should be fulfilled also for conclusive proof. Expand
The Effect of Sodium on Potassium Nutrition and Ionic Relations in Rhodes Grass
TLDR
It is concluded that interactions between the levels of major elements preclude the use of a 'critical potassium level' for diagnosing potassium deficiency in Rhodes grass and an alternative diagnostic scheme which takes account of interactions between some of the major elements is suggested.

A HYPOTHESIS RELATING CRITICAL POTASSIUM CONCENTRATIONS FOR GROWTH TO THE DISTRIBUTION AND FUNCTIONS OF THIS ION IN THE PLANT CELL
TLDR
A model is proposed in which, as the concentration of K in the tissue declines, the concentration in the cytoplasm is initially maintained constant, while that in the vacuole decreases, and the hypothesis explains the observed relationships between growth and concentrations of K. Expand
