While elevated atmospheric carbon dioxide levels promote plant growth, they also lower the nutritional value of plants, which could have a more significant effect on global nutrition and food safety.
Researchers have uncovered a novel method by which plants are adjusting to the changing environment; this knowledge can be used to support plant growth while preserving its nutritional content.

The global supply of phosphorus, which is used as fertilizer and is crucial for plant growth, is constrained.
According to Hatem Rouached, an assistant professor in the College of Agriculture and Natural Resources, they cannot synthesize phosphorus the same way we can nitrogen.
To survive, humanity must improve our knowledge of how plants control phosphorus, as per ScienceDaily.
They were curious as to why the plants weren't utilizing more phosphorus, according to Rouached. And to determine whether the decline in phosphorus levels is indeed a flaw or an adaptive reaction, and to determine whether there is a method to change it so that the plants flourish and provide food that is nourishing as well.
At the subcellular level, Rouached and his team discovered that plants were avoiding overstuffing their chloroplasts by using phosphorus as a defense mechanism against rising carbon dioxide levels.
The process of photosynthesis, in which chlorophyll creates food for a plant to develop in the presence of sunshine, occurs in chloroplasts.
The production of energy for cells and photosynthesis both require phosphorus.
What was crucial to their discovery, according to Rouached, is that plants don't grow when they are forced to place a lot of phosphorus in their chloroplasts.
Scientists found that for plants to develop under elevated carbon dioxide, the rise in phytic acid levels needed to be strictly managed.
Furthermore, scientists discovered that the plants stop growing once the phytic acid levels reach a particular point.
According to Rouached, this work is the first to demonstrate the urgent need for a conversation about how to prevent plant malnutrition from the global rise in carbon dioxide.
Crops require nutrients for adequate growth and high-quality output.
Isotopes assist in identifying crops that are very effective at utilizing nutrients or that are well-adapted to poor soil fertility and help improve crop nutrition, as per IAEA.
The bioavailability of macro- and micronutrients in crops and grains could be enhanced through improved agricultural nutrient management, which is a requirement for satisfactory crop growth and ideal quantity and quality yields.
Vital nutrients are essential for maximizing crop output and enhancing the plants' resilience to climate change, in addition to water, sunshine, and favorable soil conditions.
The quantity of alternate source inorganic nitrogen fixed and provided to the soil by legumes, as well as the level of carbon fixed by plants and stored in soils, can be estimated using isotopes of carbon, nitrogen, and phosphorus.
In addition, they aid in tracing the path taken by applied organic and inorganic fertilizers from the soil to the plants and the environment, evaluating and identifying crop genotypes tolerant to salinity and drought, and assessing phosphorus dynamics in the plant-soil continuum to enhance phosphorous management in agro-ecosystems.
Micronutrient dynamics in soil and crops are measured using isotopes of zinc, iron, and other micronutrients.
