Plants which aid in replenishing nitrogen in agricultural lands are called "nitrogen fixing" plants. Most of these actually host a bacteria in the roots of the plant that actually converts nitrogen to a formulation that can be used by plants. This is then stored in the roots as nodules.
Most legumes are considered Nitrogen fixing although the most commonly used for this purpose is Clover.

How do plants obtain the nitrogen they need?
Some plants are leguminous and have root nodules by which they are able to directly absorb the nitrogen from the atmosphere. If the are not leguminous, they get the nitrogen from the soils via their roots. For the same purpose of supplying nitrogen to the plants, farmers also add nitrogenous fertilizers to the soil which provides sufficient amount of nitrogen to the plants
What effect do plants have on human respiration?
Oxygen is a gas that does not naturally replenish itself in the atmosphere and requires the work of photosynthesizing plants to replenish it. Humans breath oxygen that plants produce and the plants breathe the carbon dioxide that humans produce.
How leguminous plan important for us?
Legumes are important for two reasons. One, the bacteria on their roots convert atmospheric nitrogen into ammonia, which is a form of nitrogen that plants can utilize. Two, many types of legumes are important food crops. As a result, legumes are the most commonly used plants in crop rotation. Legumes can be grown on nitrogen depleted soil and will replenish the soil's nitrogen levels for future crops, and at the same time they provide useful food for humans.
When there is not enough nitrogen in the atmosphere for plants how do the plants get it?
Plants do not actually get their nitrogen from the atmosphere. They get it in compounds in the soil through their roots. Some plants form symbiotic relationships with bacteria in the soil. The bacteria draw nitrogen from the air and form nitrogen compounds. The plants can then use the nitrogen.
Why do farmers grow leguminous crops between 2 other plants?
They have nodules on their roots which contain nitrogen fixing bacteria. These take the nitrogen from the air and convert it to nitrogen compounds in the soil which plants use as nutrients. In short, using leguminous plants increases the fertility of the soil.
Why do farmers put nitrogen on their plants?
What organic molecules is nitrogen found in

Why farmers prefer to grow bean and peas in nitrogen deficent soil?
They are capable of converting atmospheric nitrogen into nitrogen that can be used by plants. They make the soil better.
Why farmers use fertilizers containing nitrogen?
Nitrogen is an essential plant nutrient, especially for growth. Some plants require more nitrogen than others.
How do plants and animals get nitrogen if not the atmosphere?
if not from the atmosphere , they must depend on a process called nitrogen fixation. They get it from the soil. That's why farmers add fertilizer to the soil to increase nitrogen content

Why is it important for nitrogen to be recycled in an ecosystem?
Nitrogen is one of the elements present in nitrates which is a mineral that plants need for growth. Nitrogen fixing soil bacteria take the nitrogen from the air and change it into ammonium, and then further changed by nitrifying bacteria into nitrates. these nitrates are then taken up by the plants.
Why do some farmers put ammonium nitrate on there farmland?
because plants need nitrogen to make proteins
Why did medieval farmers grow peas or beans on their land for one out of three years?
Peas and beans belong to a very special group of plants known as legumes. Legumes are plants which have a bacteria living symbiotically in their roots which "fix" nitrogen for use by the plants themselves and thos that eat the plants. By planting legumes every 3 years, the farmers were using a natural form of nitrogen fertilizer!
Is nitrate reduction beneficial to farmers?
Nitrate reduction is not good for farmers. Nitrate reduction is the substitution of nitrates for oxygen as a terminal electron acceptor for bacteria. This means the nitrate (NO3-) then becomes nitrite (NO2-), and if the process stays anaerobic and continues, then the nitrite is reduced to nitrogen gas (N2) which then escapes from the soil. Many plants thrive on nitrates, however if they are reduced to nitrogen gas, then the available nitrogen is reduced and the plants don't do as well. This is why a good deal of fertilizers that farmers put on their fields are chock-full of nitrates.
What has the author Ya Tang written?
Ya. Tang has written: 'Nature's bounty, nitrogen-fixing plants for mountain farmers' 'Performance and selection of nitrogen-fixing Hedgerow species'
Why do farmer gardener turn the soil up regularly?
Farmers turn their soil to replenish valuable nutrients such as nitrogen and oxygen to the soil. If a farmer was to continually use the soil over and over again the nutrient level would be depleted and be deamed useless. Soil need nutrients to survive and allow other plants to grow.
