There are 7 essential plant nutrient elements defined as micronutrients [boron (B), zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), molybdenum (Mo), chlorine (Cl)]. They constitute in total less than 1% of the dry weight of most plants
Micronutrients are crucial for plant growth and play an important role in balancing crop nutrition. Micronutrients, though needed in minute amounts play an important role in most enzymatic reactions as they act as co-factors for enzymes.
Micronutrients help the major elements to perform their functions. If they are not present, the major elements will not be able to perform their duties even if you supply them. Here is the list of micronutrients that are popularly known to be as best micronutrients for plants in India.
The common roles are overall plant growth, photosynthesis, chlorophyll formation, cell wall development resistance to plant disease, nitrogen fixation, colour of the fruits, sugar transport, fruit textures, the turgidity of the plant, and osmotic balances. Water Water-soluble micronutrients are meant to supply sufficient plant nutrients to aquatic plants, irrespective of their size.
