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
What plant family helps return nitrogen to the soil?
Legumes fix nitrogen 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.
How is nitrogen essential?
Nitrogen is essential to growing plant and ammonia (NH4) is the main constituent of fertilisers. Most plants cannot make their own fertiliser but the legume family (peas,beans, clover) are very important because their roots contain nodules which contain Nitrogen fixing bacteria. In crop rotation systems these plants are ploughed back into the soil at the end of the growing season in order to improve soil fertility
What are two substances that contain nitrogen?
Air and soil.
Which element found in the soil is used by plants in the form of chemical compounds?
Nitrogen is needed by plants and they get it from the soil in compounds that contain the nitrogen.
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.

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

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.
How do plants use sulphur?
Plants cannot make protein from pure carbohydrate, because proteins contain nitrogen and sometimes sulphur. They get the nitrogen which they need from the nitrates in the soil. They get the sulphur from sulphates in the soil.
What the soil provides for plants?
As part of the nitrogen cycle, the soil provides nitrate ions (NO3-) for plants. Fertilizers also contain a lot of nitrate.

What role does decay play in the nitrogen cycle?
The decomposers , bacteria, and fungi, break down waste and dead organisms returning nitrogen they contain back into the soil.
How can someone increase the nitrogen in the soil?
Lightning increases nitrogen in the soil
