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
What converts nitrogen in the nitrogen cycle?
okay heres the nitrogen cycle nitrogen from atmosphere it taken in by 1)lightning( its energy causes nitrogen to react with oxygen n rain to the soil) 2)nitrogen- fixing bacteria in nodules ( plant roots which take it directly form the atmosphere ) NITROGEN FROM SOIL to organisms 1)nitrogen fixing bacteria in soil - breakdown of dead plants n animals releases nitrogen to the soil 2)fertilizers - which contain nitrogen compounds eg NPK OR natural fertilizers i,e dead plants n animals release nitrogen , animal urine and faeces release nitrogen as well to the soil 3)nitrogen fixing bacteria in nodules get nitrogen from its compounds in the soil 4)nitrifying bacteria - converts compounds of ammonia into nitrates .. for the plant nodules NITROGEN TO ATMOSPHERE 1) denitrifying bacteria in soil - changes nitrates to nitrogen gas and its released back to the atmosphere
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.
Where does nitrogen in the soil come from?
Nitrogen compounds known as Nitrates found in the soil
Which bacteria live in soil and fix nitrogen as part of the nitrogen cycle?
Leguminous plants contain symbiotic bacteria called Rhizobia within nodules root systems, producing nitrogen compounds that help the plant to grow and compete with other plants. When the plant dies, the fixed nitrogen is released, making it available to other plants and this helps to fertilise the soil.
What is an example of adding nitrogen to soil?
An example of adding nitrogen to soil is by incorporating organic matter such as compost or manure. These materials contain nitrogen-rich compounds that can be broken down by soil organisms to release nitrogen for plant uptake. Another method is using nitrogen-based fertilizers, which directly supply nitrogen to the soil for plants to use.
How by growing pulses Increases the soil fertility?
Roots of the plant contain a bacteria called rhizobium, and they could convert the atmospheric nitrogen into compounds of nitrogen in the soil, thus improving the soil fertility.
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

How much nitrogen is in the soil?
Nitrogen content in soil can vary widely depending on factors like soil type, location, and management practices. On average, soils typically contain around 0.1-0.5% nitrogen by weight. Soil testing can provide more accurate information on nitrogen levels in a specific area.
Does rain water contain nitrogen?
Rain storms deposit inorganic atmospheric nitrogen directly into the soil Jason Tyrrell
What minerals do Maryland's soil contain?
Nitrogen, phosphorus and potassium in abundance and others as trace minerals.
Which element found in the soil is used by plants in the form of chemical compounds?
Plants use nitrogen in the form of chemical compounds such as nitrates, ammonium, and amino acids found in the soil. Nitrogen is essential for plant growth and is a key component of proteins, chlorophyll, and nucleic acids.
What are two substances that contain nitrogen?
Two substances that contain nitrogen are ammonia (NH3) and nitric acid (HNO3). Both of these substances are commonly used in various industrial and agricultural applications.
What does not increase the amount of nitrogen in the soil?
It doesn't. Harvesting removes soil nitrogen
Which biochemical cycle aids plants through bacterila nodules in soil?
The nitrogen cycle aids plants through bacterial nodules in soil. These nodules contain nitrogen-fixing bacteria, such as Rhizobium, that convert atmospheric nitrogen into a form that plants can use for growth and development. This symbiotic relationship between plants and nitrogen-fixing bacteria helps increase nitrogen availability in the soil, benefiting plant growth.
Does sand from a beach contain nitrogen?
Sand from a beach does not typically contain nitrogen. Nitrogen is an essential element for plant growth and is usually found in soil or organic matter. Beach sand is primarily composed of silica and other mineral particles that do not contain significant amounts of nitrogen.
