Essential Mineral Elements Minerals, Functions

The mineral concentration that reduces the dry weight of plant tissue by 10% is considered toxic. The critical concentration varies for each micronutrient and the toxicity level for any element also varies for different plants. Therefore, toxicity symptoms are difficult to identify. Moreover, the excess of one element may inhibit the uptake of
