Why might farmers plant legumes such as peas to to improve the nitrogen levels in their soil?

legumes contain high level of nitrogen which are leeched into the soil. this allows the farmer to then plant crops such as corn that use that nitrogen

The sources of increased nitrogen levels on agricultural land?
There are several sources of increased nitrogen levels on agricultural land. These include the application of synthetic fertilizers, animal manure and urine, as well as nitrogen-fixing crops like legumes. Runoff from livestock operations and the use of nitrogen-based pesticides can also contribute to elevated nitrogen levels in agricultural soil. Additionally, atmospheric deposition from industrial activities and automobile emissions can deposit nitrogen onto farm fields.
Is nitrogen an asphyxiant?
Yes Nitrogen is a simple asphyxiant that is without other significant physiologic effects. Inhalation of nitrogen is dangerous only when it lowers the available oxygen in air to below life-sustaining levels
Do most organisms use nitrogen in the form of nitrogen gas?
No. They can not use nitrogen gas because the triple bonds of nitrogen can only be broken down for use in living things, plants, by the symbiotic bacteria in the root nodes. Then in other forms nitrogen is taken up into the plant and from there to other trophic levels.
What is the solubility of N in water?
The solubility of N in water is nil. N is the symbol for nitrogen and this gas does not dissolve in water. However nitrogen as a compound will have different solubility levels.
Explain why not planting a crop and then ploughing in the fall might help a farmer restore nitrogen and phosphorus levels in the soil?
When the plant stores the nitrogen in the roots, it produces a lump on the root called a nitrogen nodule. The roots can reserve the Nitrogen and Phosphate for a very long time.
Why might farmers plant legumes such as peas to improve the nitrogen levels in the soil?
legumes contain high level of nitrogen which are leeched into the soil. this allows the farmer to then plant crops such as corn that use that nitrogen
How might transferring specific genes from legumes into rice plants help reduce malnutrition?
Legumes improve the nitrogen levels in the soil, and in turn improves the growing conditions for the rice plants.
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.
Which crop is grown between two cereal crops to restore the fertility of soil?
A legume crop is typically grown to help restore the nitrogen levels.

How do farmers replace nitrogen in the soil?
There are two ways plants put nitrogen into the soil one is decomposition where a plant dies then decomposes putting the nitrogen back into the soil that it once took out. The other is from the air, Legumes are plants that take nitrogen from the air with their leaves and release it into the soil with its roots.
Explain why levels of nitrogen are why levels of nitrogen are the same in air breathed in as air breathed out?
Because the body does not use the nitrogen in any way.
How do you test your nitrogen levels?
kjehdahl method
Is precipitation linked to the nitrogen cycle?
precipitation is linked to the nitrogen cycle because air contains nitrogen and when the rail falls there's an average of about 12% nitrogen in the water that falls, which affects the nitrgen cycle by boosting nitrogen levels up to aproximetly 12g of nitrogen per 5m squared, which the added nitrogen levels may affect delicate ecosystems if not properly managed. The increase in nitrogen levels is often caused by gases containing nitrogen being released into the atmosphere.
How do famers change the nitrogen levels of farms?
There use fertilisers.
Which is true about American farmers in the 1880's?
American farmers faced economic challenges in the 1880s due to falling crop prices, high debt levels, and monopolistic practices by railroad and grain companies. Many farmers organized alliances and movements to advocate for their rights and push for reforms to improve their economic conditions. These challenges eventually contributed to the populist movement.
What are the sources of increased nitrogen levels on agricultural land?
Fertilizer application.
