Describe in brief about the Boron - Micronutrients

Boron is required in extremely small amounts in the range of 0.01 to 1.0 ppm. The actual amount may vary from crop to crop but seldom exceeds 33-56 kg of borax per hectare when broadcast (spread in the form of a shower from above) or 4.5 kg when applied in the rows.

It influences cell development by affecting the polysaccharide formation and regulates Trans location of sugars across membranes.
It affects the intake of calcium and its efficient utilisation by the plant.
It acts as a regulator of the K⁺/Ca²⁺ ratio.
It is intimately related to the absorption of nitrogen and is necessary in cell division.
It appears to be fixed in plant tissues so that it cannot move to parts where it is most needed. As a result continuous supply is needed to meet plant requirement.
If plant contains a large supply of potassium there is a boron deficiency.
