How is nitrogen depleted from soil?
Nitrogen can be depleted from soil through plant uptake, leaching, and runoff. Plant roots absorb nitrogen from the soil to support growth, which can lead to a decrease in soil nitrogen levels over time. Additionally, excess water can cause nitrogen to leach out of the soil and into groundwater, or runoff can transport nitrogen into bodies of water, further depleting soil nitrogen.
Why does a pitcher plant feed on insects although it is green?
pitcher plants are grows in soil which does not have much nitrogen in soluble form. they trap insect because they have nitrogen in their bodies.
How atmospheric nitrogen enters the soil?
Typically, atmospheric nitrogen gets into the soil by nitrogen-fixing bacteria that are symbiotic with such plants as clover, soybeans and alfalfa. Bacteria in the plant extract nitrogen from the air, and when the plants die, the nitrogen remains in the soil as the plant decays.
What are green manure?
Green manure is the term given when a farmer or gardener plants a nitrogen or other mineral rich plant into a growing plot to enrich the soil. Then, once the plant has matured to a certain point, it is plowed back into the soil to build it up.
How nitrogen in soil is detected?
All soil contains nitrogen - it is a matter of how much. The relative amount of nitrogen in soil can be determined with as small soil sample and a reagent for nitrogen from a soil test kit (simple soil test kits are sold in every garden center). The results do not tell you the "amount" of nitrogen in the soil, only if there is enough for healthy plant growth, or if the amount of nitrogen is too poor for healthy plant growth
What plant family restores nitrogen to the soil?
Legumes are the plant family that restores nitrogen to the soil. Most of legumes have symbiotic nitrogen-fixing bacteria in structures called root nodules.
Which two elements are added to soil by fertilizers?
Nitrogen and phosphorus are commonly added to soil through fertilizers to promote plant growth. Nitrogen helps with leafy green growth and overall plant development, while phosphorus is important for root growth and flower/fruit development.

Which plant enriches the nitrogen content in soil?
sugarcane
The nitrogen cycle may be described as nitrogen moving from the air to the soil where plant roots use it as food. when plants die nitrogen is returned to the air true or false?
false, when the plant dies in this case, nitrogen is returned to the soil
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
