Plant nutrition - Wikipedia
Plants take up essential elements from the soil through their roots and from the air through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H ) into the soil through proton pumps. These hydrogen ions displace cations attached to negatively charged soil particles so that the cations are available for uptake by the root. In the leaves, stomata open to take in carbon dioxide and expel oxygen. The carbon dioxid

Role of Nutrients in Plant Growth and Development SpringerLink
2020.4.26 Depending on the basic requirement of plants, nutrients are divided into two categories: micronutrients and macronutrients. Soil and plant tissue analysis reveals certain facts about the presence of each element in plant and their permissible limit in soil. Optimum limit of each element is beneficial for plant growth as well as soil fertility.

Concentration of Nutrients in Leaves, Flowers, and Fruits of
In leaves, there is a decreased concentration of macronutrients considered mobile in the plant during the reproductive phase. This decrease results from the migration of photoassimilates and mineral elements to drains, such as flowers and fruits, after the degradation of cellular compounds [ 16 ].
