What plant family helps return nitrogen to the soil?
Legumes fix nitrogen in the soil.
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.
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.
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.
Which part of the plant uses nitrogen and what for?
The roots extract nitrogen from the soil.
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.
Nitrogen fixation is a process that changes plant and soil into nitrogen compounds?
True
How nitrogen enters the atmosphere?
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.
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 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
