They are caused by a symbiotic bacteria which benefits the plant by fixing atmospheric nitrogen (which the plant needs to make proteins).

The nodules contain bacteria which can convert atmospheric nitrogen into ammonia.

What are two advantage of legume crops?
They have nodules on the roots which has nitrogen fixing bacteria
What is the purpose of these nodules?
For extra grip in case you fall.
Is groundnut legume?
Ground nuts are legumes. Groundnut being a legume crop utilizes the nitrogen in the atmosphere by nitrogen fixation in association with a group of bacteria belonging to Rhizobium family. The Rhizobium bacteria penetrate the roots of legumes and form root nodules .
Why legiminous plants have root nodules?
It contains bacteria that fix nitrogen in the soil. This provides this vital element not only for the legume but also other plants in the vicinity
What puts nitrogen in soil?
Nitrogen fixing bacteria that live in root nodules of members of the legume family of plants. Some Nitrogen is also fixed during lightning strikes.
What is the signification of growing legume plants in crop production?
Legumes have root nodules which contain bacteria which are able to use nitrogen from the air to create nitrogenous compounds, which fertilize the plant.
How does nitrogen into the atmosphere move into the soil?
Some of it is fixed by legume plants - or more precisely by bacteria in plant nodules. Some gets there by when compounds created by lighting dissolve into the accompanying rain.
What converts nitrogen in the air to help form plants?
Plants called legumes. Actually it is the bacteria that reside in nodules contained in the legume's roots that perform the 'nitrogen fixation' biochemical process.
How do plants get nitrogen from the soil?
Nitrogen-fixing bacteria in nodules on plant roots (legume plants; beans, peas, alfalfa) convert nitrogen in the air (ammonia) to nitrites then nitrates which is then absorbed by plants through their roots.
Soil is deprived of nitrates what do you plant?
Virtually anything in the Legume(pea and bean) family will produce nitrogen as these form nodules with Rhizobacteria which convert N2 gas to nitrate. You can plant vetch, soybeans, dry bean plants, pea plants, and any other plant that is a Legume. You can also apply Nitrogen fertilizer as well and Nitrates will be made as it ozidizes.
How does nitrogen in the atmosphere move into soil?
Some of it is fixed by legume plants - or more precisely by bacteria in plant nodules. Some gets there by when compounds created by lighting dissolve into the accompanying rain.
What is the symbiotic relationship legume plants and rhizobium bacteria?
The bacteria live in the plant cells, located on the root, and form nodules. These nodules convert nitrogen gas in the soil to usable energy for the plant. In return, the bacteria have a safe place to live and reproduce.
