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… 
What is a plant nutrient? Changing definitions to advance science and innovation in plant nutrition
Current definitions of essential or beneficial elements for plant growth rely on narrowly defined criteria that do not fully represent a new vision for plant nutrition and compromise fertilizer
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 a

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 nutritional
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-inoculated
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.
Non-Essential Elements and Their Role in Sustainable Agriculture
Agricultural systems are constantly under environmental pressure, and the continuous rise of the global population requires an increasingly intensification of agronomical productivity. To meet the
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 osmotic

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.
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.
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.
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.
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.
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.

Sodium as an Essential Micronutrient Element for Atriplex vesicaria, Heward
TLDR
The object of this communication is to record sodium as an essential micro-nutrient element for the bladder saltbush to describe the visual deficiency symptoms when plants were grown in solutions carefully freed from sodium and the recovery of such deficient plants on addition of sodium salts.
