We have always heard and believed that Nitrogen is the most important nutrient!! The fact is Nitrogen is just one of the important nutrients required by plants. However the producers of chemical fertilizers have somehow succeeded in convincing us that Nitrogen is the most important nutrient. To judge how important any element is; let us first understand the macro and micro nutrients required by plants. The following is a simplified version of the study of nutrients!



GROUP I : Carbon, Oxygen and Hydrogen : These are the most important nutrients without which the plants cannot survive for a long time.

GROUP II : Nitrogen, Phosphorous and Potassium : These are again very important ย nutrients required for flowering and fruiting of plants.

GROUP III : Calcium, Magnesium and Sulphur : These are required in little quantities however are important.

MICRO NUTRIENTS : All other elements fall into the micro nutrient category like iron, zinc, sodium, chlorine, copper, etc. They are required by plants in a very minuscule quantity.

  1. Thanks for sharing this information and aware readers how other elements play vital role for plant development. I would like to add something in it.
    Nitrogen fixing bacterial culture like clostridium, ribozium & azatobactor are also available in agro research center which is totally natural and biological agent which fix atmospheric nitrogen and make them available to plant as we all know atmosphere cantain 72%nitrogen, 23%oxygen &5%other gases. So for nitrogen requirement one can use this culture which is chemical free and totally natural.

    1. Thank you sarang for your feedback !! ๐Ÿ™‚ I really appreciate your feedback!! yes we do get these cultures. Rhizobium is found in legumes and it is in symbiotic relationship with the legumes; which means that the bacteria cannot survive by itself. The bacteria is dependent on the plant. Hence to fix nitrogen using rhizobium one has to plant legumes in rotation with other crops. Azotobacter is an excellent option suggested by you !!
