“…Average daily dietary intake of Si is 20–50 mg for European population, the RDA has not been stablished; however, safe upper levels for humans have been recommended with a maximum range of 700–1750 mg day −1 [ 135 ]. Silicon is considered not essential for plant nutrition, but its inclusion in fertilization programs has proved to increase the crop tolerance to biotic and abiotic stressors [ 136 ], crop yield [ 137 ], or improve the absorption of macro- and microelements [ 138 ]. Silicon concentration in soil can vary depending on the type of soil.…”

Vegetables represent pillars of good nutrition since they provide important phytochemicals such as fiber, vitamins, antioxidants, as well as minerals. Biofortification proposes a promising strategy to increase the content of specific compounds. As minerals have important functionalities in the human metabolism, the possibility of enriching fresh consumed products, such as many vegetables, adopting specific agronomic approaches, has been considered. This review discusses the most recent findings on agronomic biofortification of vegetables, aimed at increasing in the edible portions the content of important minerals, such as calcium (Ca), magnesium (Mg), iodine (I), zinc (Zn), selenium (Se), iron (Fe), copper (Cu), and silicon (Si). The focus was on selenium and iodine biofortification thus far, while for the other mineral elements, aspects related to vegetable typology, genotypes, chemical form, and application protocols are far from being well defined. Even if agronomic fortification is considered an easy to apply technique, the approach is complex considering several interactions occurring at crop level, as well as the bioavailability of different minerals for the consumer. Considering the latter, only few studies examined in a broad approach both the definition of biofortification protocols and the quantification of bioavailable fraction of the element.

“…Application of Si facilitated mobility plus xylem translocation of Fe towards shoot, along with cells buildup of Fe mobilizing elements as citrate (xylem sap, root and shoot tissues) and perhaps catechins (in roots). Reliant on these findings, Si’s treating outcome appears to be a lot more indirect, by negatively affective activation of Fe deficiency associated genes accountable for improved root acquisition and Fe’s cell mobilization (Kaushik and Saini, 2019). Despite, the most plentiful element in the Earth’s crust, metallic (Fe) deficiency is one of the main limiting factors for crop generation in calcareous soils all around the globe (Vose 1982; Romera et al ., 2019).…”

Eucalyptus is a commonly planted tree in North India and its cultivation area is increasing. Leaves of Eucalyptus are used for tea which has healing properties and many other economic uses. Silicon is the second most abundant element in the earth’s crust next to oxygen. Silicon (Si) can improve photosynthesis, decrease transpiration, increase water use efficiency and provide resistance against biotic and abiotic stress. The clear information was not available regarding Silicon nourishment in tree species like Eucalyptus. Although a positive in plant development and overall dry matter production was noticed in Eucalyptus with Si application. The amount of nitrogen (N), phosphorus (P), and potassium (K) were inclined leaf whereas Calcium (Ca) and magnesium (Mg) content was not affected by Si application potassium silicate (K2SiO3). Finally results revealed that upon Si application significant increase in the leaf mineral content in almost all genotypes was recorded. Correlation studies revealed that leaf N and P were highly and significantly correlated with leaf copper (Cu) and iron (Fe) content, leaf Mg and leaf Cu were positively and significantly correlated with leaf N, manganese (Mn) and Fe content, leaf Mn and Fe content were highly and significantly correlated with leaf N, Mg and Cu content. To our detailed knowledge this is the first ever study conducted in Eucalyptus. Here the influence of potassium silicate on popular North Indian cultivars’ leaf mineral content Nevertheless, more studies are required to analyze the effect of Si application in tree species like Eucalyptus.

“…Soil fertility is usually determined based on the presence or absence of nutrients, i.e. macro and micronutrients 1,2 . Out of 17 critical plant nutrients Nitrogen (N), Phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sulphur (S) are macronutrients.…”

Soil fertility determines the successful development of a plant, and therefore it is important to achieve food security. Imbalanced and inadequate use of chemical fertilizers, irregular irrigation and harmful cultural practices deplete the soil profile nutrient profile, which is critical for the successful crop production. This study presents the results of the classification of the states across India based on their soil macronutrient profile. The entanglement coefficient of Unweighted Pair Group Method with Arithmetic Mean (UPGMA) and the neighbour-joining method was 0.81. Absolute correlation values were determined among the different classes of the soil nitrogen content and the corresponding classes of the soil phosphorus content. The K-mean clustering method divided the states and union territories into the three clusters. Overall, this works represents the grouping of Indian soils based on their soil macronutrient and organic carbon content.
