Describe briefly how nutrients are replenished in the soil? how is the growing of a leguminous crop in the field beneficial to the farmer?

give me the big and explaination answer​

Answer 1

Answer:

Nutrients are replenished by certain different microorganism that are found in thesoil or also by the death of certain plants such as the rhizobium bacteria. The decaying plants tend to slowly break down into the basic soil nutrients over a period of time

Explanation:

rhizobium bacteria live in the root nodules of legumes, it helps in converting nitrogen into a soluble form and remove the deficiency of nitrogen in soil

Answer 2

We can replenish cropes by following methods

• By crop rotation
• By using manure
• By using fertilizer (but we should use fertilizer in small amount)
• By using leguminous cropes

By using manure made up of Vermicomposting ( because it contains more Neutrients)

Now, leguminous cropes can be beneficial for farmers because

• It contains Risobium bacteria in their roots which help in nitrogen fixation.
• Due to this it reduses the use of fertilizer in farms.
• If the use of fertilizer in farms reduce then the watter and soil pollution also reduce.
