Nutrient Use Efficiency of Micro Nutrients is

Nutrient use efficiency (NUE) shows the ability of crops to take up and utilize nutrients for maximum yields. It involves three major processes in plants: uptake, assimilation, and utilization of nutrients. Nutrient Use Efficiency of Micronutrients is 2% - 5%.
The seven micronutrient elements are boron, zinc, iron, copper, molybdenum, manganese and chlorine.
