After reading this article you will learn about the passive and active transport of ions from the epidermis to xylem in plants. Passive Transport of Ions: Transport of ions from the epidermis to the xylem without any consumption of metabolic energy merely in consequence of the spontaneous disappearance of non-equilibria driven by a decrease in free enthalpy is known as [...]
In this article, some of the important interactions between nutrient elements as well as between nutrients and other factors are being described briefly. Nitrogen and Micro-Nutrients: Applied N has been reported as a possible cause of Zn deficiency in citrus plants. The application of N fertilizer accentuated the uptake of P and Zn by potatoes.

After reading this article you will learn about nitrogen in relation to physiology, growth and response of crops. Nitrogen in Relation to Physiology of Plants Nitrate (NO3—N) and ammonium (NH4—N) are two major forms of inorganic nitrogen taken up by the plants. Most of the ammonium has to be incorporated into organic compounds in the plant roots, whereas nitrate is [...]
