“…However, they are in dimensions similar to or smaller than a number of anaotomous structures of plant tissues, e.g., plasmodesmata, cell wall pore sizes, or stomates [ 233 ]. Therefore, the presence of nanoparticles in foliar fertilizers improves the bioavailability of nutrients due to the nano-size, large specific surface area and greater reactivity of the compounds [ 234 ]. Fertilizers applied to the soil create the possibility that particles in the “nano” size may not be easily fixed between sheets of secondary minerals, and so not easily leached away from the soil [ 235 ].…”

Fertilizer Use Efficiency (FUE) is a measure of the potential of an applied fertilizer to increase its impact on the uptake and utilization of nitrogen (N) present in the soil/plant system. The productivity of N depends on the supply of those nutrients in a well-defined stage of yield formation that are decisive for its uptake and utilization. Traditionally, plant nutritional status is evaluated by using chemical methods. However, nowadays, to correct fertilizer doses, the absorption and reflection of solar radiation is used. Fertilization efficiency can be increased not only by adjusting the fertilizer dose to the plant’s requirements, but also by removing all of the soil factors that constrain nutrient uptake and their transport from soil to root surface. Among them, soil compaction and pH are relatively easy to correct. The goal of new the formulas of N fertilizers is to increase the availability of N by synchronization of its release with the plant demand. The aim of non-nitrogenous fertilizers is to increase the availability of nutrients that control the effectiveness of N present in the soil/plant system. A wide range of actions is required to reduce the amount of N which can pollute ecosystems adjacent to fields.

“…Research in plant nutrition removes these restrictions and, as a result, provides important knowledge that is extremely beneficial in ensuring sustainable food security and well-being for humans without harming the environment [5]. To achieve the desired crop yield, chemical fertilizers are overused [30]; however, chemical fertilizers have been used for centuries and have greatly enhanced agricultural yields [31]. The overuse of chemical fertilizers has resulted in soil, environmental, and aquatic pollution, particularly soil mineral imbalances, degraded soil structure and soil fertility, soil quality deterioration, eutrophication, and ground water and air pollution, all of which are severe long-term barriers.…”

“…Furthermore, the uncontrolled use of chemical fertilizers boosts production costs while decreasing farmer profit. To keep intensive agriculture productive while decreasing negative environmental consequences, systematic measures to restore natural resources are essential [30,31]. It has also been observed that traditional agricultural techniques are related to excessive usage of agrochemicals.…”

“…Damage to agricultural soil constitute a serious problem in developing countries, which lead to a decrease in arable lands due to urbanization and human activities, especially industrialization (Figure 6). At this point, the usage of nanohybrid constructs such as nanofertilizers (NFs) has gained prominence [30]. Nanofertilizers are nano-enabled bulk materials that are applied to increase plant nutrition.…”

“…However, the usage efficiency of supplied nutrients via fertilizers remains relatively low (N: 30-40%, P: 15-20%, K: 50-55%, and micronutrients: 2-5%). This results in excessive soil nutrients mining, resulting in a net negative soil nutrient balance of about 10 million tons and hence deteriorating soil health [30].…”

Plant Nutrition for Human Health: A Pictorial Review on Plant Bioactive Compounds for Sustainable Agriculture

et al. 2022

Is there any relationship between plant nutrition and human health? The overall response to this question is very positive, and a strong relationship between the nutrition of plants and humans has been reported in the literature. The nutritional status of edible plants consumed by humans can have a negative or positive impact on human health. This review was designed to assess the importance of plant bioactive compounds for human health under the umbrella of sustainable agriculture. With respect to the first research question, it was found that plant bioactives (e.g., alkaloids, carotenoids, flavonoids, phenolics, and terpenoids) have a crucial role in human health due to their therapeutic benefits, and their potentiality depends on several factors, including botanical, environmental, and clinical attributes. Plant bioactives could be produced using plant tissue culture tools (as a kind of agro-biotechnological method), especially in cases of underexploited or endangered plants. Bioactive production of plants depends on many factors, especially climate change (heat stress, drought, UV radiation, ozone, and elevated CO2), environmental pollution, and problematic soils (degraded, saline/alkaline, waterlogged, etc.). Under the previously mentioned stresses, in reviewing the literature, a positive or negative association was found depending on the kinds of stress or bioactives and their attributes. The observed correlation between plant bioactives and stress (or growth factors) might explain the importance of these bioactives for human health. Their accumulation in stressed plants can increase their tolerance to stress and their therapeutic roles. The results of this study are in keeping with previous observational studies, which confirmed that the human nutrition might start from edible plants and their bioactive contents, which are consumed by humans. This review is the first report that analyzes this previously observed relationship using pictorial presentation.
