Question

Define and explain:

manure fertilizer, biofertilizer, mycorrhiza diazotrophs, root nodule, Frankia, nitrogen fixation

.......... Organisms which can bring about soil nutrient enrichment.

Answer 1

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

Fertilizer - It is an organic or inorganic compound rich in plant nutrients

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

Mycorrhiza - It is a symbiotic relationship between fungal hyphae and roots of higher plants.

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.
