Micro-nutrients are essential substances that are required for healthy plant growth. There are certain biochemical functions performed by micro-nutrients that are directly associated with plant growth and their metabolism. Earlier, the focus of farmers and agriculturists was mainly based on nutrients such as nitrogen, potash, and phosphate. However, with the change in time, and the rising prevalence of crop diseases, the adoption of micro-nutrients for crop production and growth has increased
Micro-nutrients are essential for plant growth and play an important role in balanced crop nutrition.
There are 16 elements essential to growth of crop plants:
Supplied by air and water: carbon, hydrogen, oxygen
Macronutrients: nitrogen, phosphorous, potassium
Secondary Nutrients: calcium, magnesium, sulfur
Micronutrients: boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), and zinc (Zn).
