Background

Plants require 13 mineral nutrient elements for growth. The elements that are required or necessary for plants to complete their life cycle are called essential plant nutrients. Each of these nutrients has a critical function in plants and are required in varying amounts in plant tissue.

Macronutrients like Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg) and Sulfur (S) are plant nutrients required in the largest amount in plants. Micronutrients like Zinc (Zn), Boron (B), Iron (Fe), Copper (Cu), Manganese (Mn) molybdenum (Mo) and Chlorine (Cl) etc are required in relatively smaller amounts.

Boron - An Essential Plant Micronutrient

Boron is an essential nutrient required for all plant growth and must remain available for plant uptake during the growth period.

Boron plays an important role in Sugar transport Cell wall synthesis Lignification Cell wall structure Carbohydrate metabolism RNA metabolism Respiration Membranes Root growth Pollination

Boron Deficiency

Boron deficiency & positive response to B application has been reported in over 80 countries and on 132 crops over the last 60 years.

Earliest effect of boron deficiency in plants and trees is observed in outer membrane of cytoplasm of root cells, which are, altered in such a way that absorption of phosphorus, chlorides and potassium from the soil is reduced. Poor or weak root system affects the absorption of nutrients from soil and it also affects absorption of sugar cell in membrane.

Boron deficiency is particularly observed in root crops, leafy vegetables, fruit trees, tea, coffee, tobacco, olive tree, oil palm etc. In olive trees suffering from boron deficiency the yield drops drastically.

Main consequences of boron deficiency in plants and trees, which can be easily seen, are as below

• Leaves become misshapen, small, thick and brittle,
• Growing points start dying
• Watery patches develop in storage tissues
• Fruit development is irregular and misshapen
• Root growth is impaired

The best way to detect the boron deficiency is soil tests without causing any adverse effect on growth and yield.

Correcting Boron Deficiency

Boron deficiency can be remedied by correct & timely application of Chemiebor and / or Agricol range of straight B-fertilizers manufactured by Raj Borax. Chemiebor is a complete range of B-Fertilizers containing varied amounts of Boron (as B) ranging from 11% upto 20% in all physical forms (Crystal, Crystalline, Granules & Powder) & customized packings to suit the needs of the farmers & bulk fertilizer industry.Application of Boronated / Boron blended bulk fertilizers like Boronated SSP, Boronated NPK, Boronated DAP etc. is another effective way of correcting boron deficiency.
