BIO FERTILIZERS

living microorganisms which, when applied to seed, plant surfaces, or

soil promotes growth by increasing the supply or availability of primary nutrients to the host plant.

fixation, solubalizing phosphorus, and stimulating plant growth through the synthesis

of growth promoting substances.

Biological Fixation of N2

improve the nitrogen supply available to the plants. 
 

which plants can absorb easily. 1) Proteins - Amino Acids 2) Carbohydrates

& Fibers - Sugars 3) Fats - Fatty Acids
Role of Soil Bacteria
Soil-bacteria release biochemical which accelerate the plant growth.
They scavenge phosphate from soil layers.
They increase the availability of nutrients.
