Question

1.Manure fertilizer, biofertilizer, mycorrhiza, diazotrophs, root nodule, Frankia, nitrogen fixation

2. .......... is an Inorganic, or organic compounds rich in plant nutrients.

Answer 1

Manure - It is the natural material which is obtained by decaying plant and animal waste.

Biofertilizer- These are living microorganisms which fix nitrogen bacteria in roots of the plants.

Mycorrhiza- It is a symbiotic association between a fungus and vascular plants.

Diazotrophs- These as bacteria that fix atmospheric nitrogen gas into a more usable form.

Root nodule- These are associated with symbiotic nitrogen fixation which occurs at roots.

Frankia-It is the genus of nitrogen-fixing bacteria which lives in symbiotic form.

Nitrogen-fixation- It is a process in which the atmospheric nitrogen is converted into ammonia.

"Fertilizer is inorganic, or organic compounds rich in plant nutrients'.
