Question

1.
Can association between rhizobium and root nodules of leguminous plants be termed as a
symbiotic association? If yes, how? If not, why?
2. What are the different ways of replenishing soil nutrients do you suggest if you were to grow
some crops in your garden?
​

Answer 1

Answer:

1.Legumes use nitrogen fixing bacteria, specifically symbiotic rhizobia bacteria, within their root nodules to counter the limitation. ... The plant root cells convert sugar into organic acids which then supply to the rhizobia in exchange, hence a symbiotic relationship between rhizobia and the legumes.

2.Methods of "replenishing nutrients" in the soil are:

a. Composting: Addition of organic naturally decayed matter in the "form of compost" or aged manure are either tilled or sprayed. ...

b. Cover crops: Mulch or cover crops are grown in between "growing seasons". ...
