Question

What are the different ways of replenishing soil nutrients .Can association between rhizobium and
root nodules of leguminous plant be termed as a symbiotic association? If yes, how? If not, why?

Answer 1

Answer:

Explanation:The different ways of replinishing soil nutrients are:

Multiple cropping- growing more than one crop in the same field

Crop rotation- changing varieties of crops every season

Field fallow- leaving the field for a season and letting them replenish nutrients by itself

Yes, the association of rhizobium bacteria and the root nodules of a leguminous plant can be said to be a symbiotic relationship as the bacteria provides nutrients to the plant in return the plant gives shelter to the bacteria. This is how they mutually work together.
