How are the terms ‘critical concentration’ and ‘deficient’ different from each other in terms of the concentration of an essential element in plants? How will you find the values of ‘critical concentration’ and ‘deficient’ for minerals – Fe & Zn?

Solution: The critical concentration of essential elements is the concentration of essential elements below which plant growth stops, whereas the critical concentration of essential elements is the concentration of essential elements below which deficiency of an element begins and visible signs of deficiency appear.

Hydropo is a tool that can be used to determine these values.
