What else can I help you with?
The nitrogen content of some agricultural soils may be improved by?
water ferns with symbiotic cyanobacteria, or other plants with nitrogen-fixing bacteria
What kind of nitrogen do plants need?
Bacteria and plant roots perform nitrogen fixation, which allows plants to use the nitrogen. Nitrogen is used in cells to build proteins and DNA. However, plants get their nitrogen as "nutrients" in the soil.
Plants which assist in nitrogen fixation are?
Legumes
Which organisms transform nitrogen to a form that is useful to plants?
bactieria
What is an example of nitrogen fixing a process essential for life on Earth?
The answer choices are:Plants take in nitrogen gas from the atmosphere.Bacteria convert nitrogen gas into a form that plants can use.Water absorbs nitrogen.Animals take in nitrogen gas from the atmosphere.
How do plants and animals get nitrogen if not the atmosphere?
if not from the atmosphere , they must depend on a process called nitrogen fixation. They get it from the soil. That's why farmers add fertilizer to the soil to increase nitrogen content
Why do many fertilizers have a high nitrogen content?
Nitrogen is an essential nutrient for plant growth as it helps in producing chlorophyll and proteins. Fertilizers with a high nitrogen content help boost plant growth, improve leaf development, and increase overall plant health. This is why many fertilizers have a high nitrogen content to ensure that plants receive an adequate supply of this important nutrient.

How do legumes contribute to the nitrogen content in soil?
Legumes have a special ability to form a symbiotic relationship with certain bacteria in their roots. These bacteria, called rhizobia, can take nitrogen from the air and convert it into a form that plants can use. This process, known as nitrogen fixation, allows legumes to increase the nitrogen content in the soil, benefiting not only themselves but also other plants growing nearby.
What does not increase the amount of nitrogen in the soil?
It doesn't. Harvesting removes soil nitrogen
What 2 things an increase the amount of nitrogen in the nitrogen cycle?
Two factors that can increase the amount of nitrogen in the nitrogen cycle are the use of nitrogen-based fertilizers and the process of nitrogen fixation. Nitrogen-based fertilizers, when applied to crops, enhance soil nitrogen levels, promoting plant growth. Additionally, nitrogen-fixing bacteria in the soil or in the root nodules of legumes convert atmospheric nitrogen into a form that plants can use, naturally enriching the nitrogen content in the ecosystem.
How do legumes increase soil fertility?
Legumes have a symbiotic relationship with nitrogen-fixing bacteria in their root nodules. These bacteria convert nitrogen in the air into a form that plants can use, making it available in the soil for other plants to utilize. This increases the nitrogen content in the soil, which is essential for plant growth and contributes to soil fertility.
What do plants use nitrogen to do?
Mainly to construct proteins, plants with high protein content are those which require the most.
What has the author R J Haynes written?
R. J. Haynes has written: 'Mineral nitrogen in the plant-soil system' -- subject(s): Effect of nitrogen on Plants, Effects of nitrogen on Plants, Nitrification, Nitrogen content, Nitrogen cycle, Plant-soil relationships, Soils
Why do plants need ammonia?
For its nitrogen content. Plants don't necessarily need to have nitrogen provided in the form of anhydrous ammonia, but it's a fairly common method in the Midwest part of the US.
The nitrogen content of some agricultural soils may be improved by?
water ferns with symbiotic cyanobacteria, or other plants with nitrogen-fixing bacteria
How can I increase the nitrogen level in soil?
You can increase the nitrogen level in soil by adding nitrogen-rich fertilizers, planting nitrogen-fixing plants like legumes, rotating crops, and incorporating organic matter like compost or manure into the soil.
