“…Many plant metabolites require sulfate (S), including carbohydrates and proteins, sulfolipids, and micronutrients, which are all important for physiological functions [ 78 ]. Following the significant reductions in anthropogenic sulfur emissions, less S accessibility in top soil limits plant growth [ 79 ]. The most common sulfur form consumed and translocated into different tissues for absorption is inorganic S. Sulfate uptake from topsoil is primarily accomplished through two high-affinity S carriers, SULTR1;1 (sulfate transporter1;1) and SULTR1;2 (Sulfate transporter1;2).…”

To complete their life cycles, plants require several minerals that are found in soil. Plant growth and development can be affected by nutrient shortages or high nutrient availability. Several adaptations and evolutionary changes have enabled plants to cope with inappropriate growth conditions and low or high nutrient levels. MicroRNAs (miRNAs) have been recognized for transcript cleavage and translational reduction, and can be used for post-transcriptional regulation. Aside from regulating plant growth and development, miRNAs play a crucial role in regulating plant’s adaptations to adverse environmental conditions. Additionally, miRNAs are involved in plants’ sensory functions, nutrient uptake, long-distance root transport, and physiological functions related to nutrients. It may be possible to develop crops that can be cultivated in soils that are either deficient in nutrients or have extreme nutrient supplies by understanding how plant miRNAs are associated with nutrient stress. In this review, an overview is presented regarding recent advances in the understanding of plants’ responses to nitrogen, phosphorus, potassium, sulfur, copper, iron, boron, magnesium, manganese, zinc, and calcium deficiencies via miRNA regulation. We conclude with future research directions emphasizing the modification of crops for improving future food security.

“…Humate supplies potassium humate and micronutrients essential for plant growth and soil fertility enhancement [29]. Energen is made up of potassium humate salts and trace elements which enhances plant growth as well as other ranges of physiological functions [18,21]. Biostim increases plant's resistance to drought and increases crop yield by supplying a balanced composition of nitrogen, potassium, sulphate and amino acids [19].…”

Green leafy kale (Brassica oleracea var. sabellica) has huge scientific attention because of its health-promoting functionality. In the present study the impact of NPK, energen, biostim and humate on flavonoid, phenolic compounds, vitamin C, carotenoids, malondialdehyde (MDA), protein, proline and soluble sugar in kale was investigated. The mineral nutrients mostly increased but in some cases maintained the studied metabolites. The stimulatory effect of applied mineral nutrients on the phytochemicals analyzed varied with the different combinations of macro and microelements. Lipid peroxidation was minimized in leaves treated with mineral nutrients hence a reduction in MDA levels. Contrary to the correlation between nitrogen deficiency and increase in polyphenol and vitamin C content in plants, NPK and biostim did not reduce phenolic compound levels. The results of this study showed that NPK maximized the synthesis of vitamin C and proline; energen - phenolic compounds, carotenoids and sugar; biostim – phenolic compounds, proteins and sugar; humate – flavonoids and sugar in curly kale. Therefore, the type of macronutrient and micronutrients combination increases phytochemicals in differently. To enhance the synthesis of phenolic compounds and vitamins, the most promising additives are those containing humic acids (humate and energen), and biostim proved to be more effective for the synthesis of proteins. Background. The understanding of how diet affects the incidence or treatment of disease has led to a rise in consumer’s demand for functional foods as well as created the market for natural sources of health benefitting compounds rather than the synthetic sources. Curly kale has gained scientific attention as a functional food because it contains higher levels of phytochemicals than most vegetables. These phytochemicals have shown antioxidant, antimutagenic, cytotoxic, antifungal, and antiviral activities. However, the content levels of these metabolites are influenced by not only genetic but environmental factors. It was of interest to evaluate how various mineral nutrients can elicit the accumulation of these compounds that minimize the risk of chronic diseases or aid in their treatment. Purpose. Evaluate how the mineral nutrients, NPK, energen, biostim and humate affect the content of metabolites (proteins, sugars, flavonoids, phenolic compounds, vitamin C, carotenoids, MDA and proline) in curly kale (Brassica oleracea var. sabellica). Materials and methods. Sprouts from kale seed kept wet in a Petri dish for 7 days were transferred to the field. At 6 weeks old four mineral nutrients (NPK, energen, humate and biostim) were added to the soil. Control variants were treated with water. A week later, the leaves were harvested after which, the phenolic compound, flavonoid, protein, sugar, vitamin C, carotenoid, MDA and proline contents were determined using spectrophotometric methods. Results. It was shown that humate fertilizer elicited the highest accumulation of flavonoids. Kale plants fertilized with energen were observed to have the highest phenolic compound content. NPK, energen and humate caused a similarly positive effect on vitamin C content in leaves, unlike biostim whose effect did not significantly differ from control plants. Energen treated kale had the highest increment of carotenoids. A varied reduction of MDA levels in plants treated with all four mineral nutrients was observed in kale leaves. Plants fertilized with biostim accrued the highest protein content in leaves. Proline content increased under the influence of all fertilizers studied. Sugar levels for all kale plants treated with the studied mineral nutrients were enhanced equally Conclusion. Macro and microelements supplied by mineral nutrients differentially boost the biosynthesis of health-promoting metabolites in curly kale, thereby enhancing its quality.

“…The vacuole, ER, plastids, and mitochondria contain higher Ca levels than the cytoplasm (Mitra 2015). In plant tissue, calcium is present as Ca 2+ , or as calcium carbonate, calcium phosphate, and calcium oxalate (Pandey 2018). The osmoregulation of cells is controlled by the calcium oxalate, wherein Ca 2+ is used for neutralizing anions -phosphate, citrate, malate, and/or oxalate -that may accumulate in high concentrations in vacuoles (Marschner 2012).…”

Microbial Biofertilizers and Micronutrient Availability

Micronutrients like boron, iron, manganese, zinc, and copper, although required in small quantities, are essential for plant health and growth. Excessive use of chemical fertilizers to meet the food demand is resulting in nutrient imbalances in soil, plants, and humans leading to environmental and health problems. Use of biofertilizers is an effective, economical, and sustainable approach to tackle the problem of nutrient imbalance. Biofertilizers help in maintaining the micronutrients in soil and making them available to plants. Zinc malnutrition is one of the biggest problems, as its biological consequences are severe and some of the estimates by international organizations are alarming. According to the Food and Agriculture Organization (FAO) of United Nations, 50% of the world's cereal soils are deficient in zinc. The World Health Organization estimates that approximately 800,000 people, mainly children under the age of 5, die annually due to the health complications caused by zinc deficiency. Zinc deficiency affects about 2 billion people worldwide. Various approaches are being used to combat the zinc deficiency such as increasing bioavailability of Zn to plants resulting in Zn biofortification of crops, use of supplements, and food fortification. To increase the Zn content of the plants, various strategies are used such as application of chemical fertilizers (soil and foliar spray), use of biofertilizers, and use of genetic engineering and plant breeding approaches. This chapter discusses some of the strategies used for the Zn biofortification of cereal crops.
