“…The higher rates of GNM and

I_{{NH}_{4}}

in tropical forests suggest that

I_{{NH}_{4}}

was highly dependent on soil NH 4 + availability, signifying high competition for soil available N between plants and microorganisms. However, as the MAT and MAP were significantly lower in subtropical regions than in tropical regions (Figure S1), soil microorganisms are less active, reducing the decomposition rate of soil organic matter (Fang et al, 2022; Vanisree et al, 2022), and ultimately GNM and

I_{{NH}_{4}}

rates. This was confirmed by the lower specific

I_{{NH}_{4}}

rate in subtropical forests (Figure S3b) and by the positive relationship between GNM and MAT (Figure S6c and Table S6).…”

“…Furthermore, our analysis revealed that climatic changes may influence soil N cycling rates in tropical and subtropical forests. The MAT stimulates GNM and GAN (Table S6) as a result of increased soil microbial activity (Vanisree et al, 2022), indicating the potential for increased NO 3 − accumulation in tropical and subtropical forests under projected global warming. This is further supported by the negative effect of MAT on the soil C/N ratio (Table S6), resulting in higher GAN rates in these biomes (Figure 2c).…”

“…Instead, higher MAT and lower soil C/N ratio are the key factors stimulating GAN in these biomes (Figures S9 and S17). Higher temperatures significantly enhanced soil GAN as a result of increased soil microbial activity (Vanisree et al, 2022). The requirement of microorganisms for inorganic N increases during organic C decomposition in soils with a higher C/N ratio, thus decreasing the substrate NH 4 + for nitrifiers (Brust, 2019), resulting in a decrease in the abundances of AOB and AOA which use NH 4 + as a substrate (Xiao et al, 2021).…”

“…In addition, Li et al [159] investigated the impacts of increased CO 2 on the nutritious content of soybean seeds, while Dong et al [160] described the findings of a meta-analysis to quantify the effects of increased CO 2 on the nutrient content of other vegetables. Several reports have been published on the role of global climate change in the decline of crop productivity and soil fertility due to the exposure of these soils to many frequent features of climate change such as higher temperatures, droughts, floods, desertification, and salinization resulting from extreme weather events (e.g., [154,161,162]).…”

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.

Toxicity with heavy metals has proven to be a significant hazard with several health problems linked to it. Heavy metals bioaccumulate in living organisms, pollute the food chain, and possibly threaten the health of animals. Many industries, fertilizers, traffic, automobile, paint, groundwater, and animal feed are sources of contamination of heavy metals. Few metals, such as aluminum (Al), may be eliminated by the elimination processes, but other metals like lead (Pb), arsenic (As), and cadmium (Ca) accumulate in the body and food chain, leading to chronic toxicity in animals. Even if these metals have no biological purpose, their toxic effects are still present in some form that is damaging to the animal body and its appropriate functioning. Cadmium (Cd) and Pb have negative impacts on a number of physiological and biochemical processes when exposed to sub-lethal doses. The nephrotoxic effects of Pb, As, and Cd are well known, and high amounts of naturally occurring environmental metals as well as occupational populations with high exposures have an adverse relationship between kidney damage and toxic metal exposure. Metal toxicity is determined by the absorbed dosage, the route of exposure, and the duration of exposure, whether acute or chronic. This can lead to numerous disorders and can also result in excessive damage due to oxidative stress generated by free radical production. Heavy metals concentration can be decreased through various procedures including bioremediation, pyrolysis, phytoremediation, rhizofiltration, biochar, and thermal process. This review discusses few heavy metals, their toxicity mechanisms, and their health impacts on cattle with special emphasis on the kidneys.
