There are two ways plants put nitrogen into the soil one is decomposition where a plant dies then decomposes putting the nitrogen back into the soil that it once took out. The other is from the air, Legumes are plants that take nitrogen from the air with their leaves and release it into the soil with its roots.
Farmers replace nitrogen in the soil by using fertilizers that contain nitrogen such as ammonium nitrate or urea. They can also rotate crops with legumes like clover or beans that fix nitrogen from the air into the soil. Additionally, some farmers use organic matter like compost or manure to add nitrogen to the soil.
You can add natural components such as compost or horse manure and dig it into the soil.
You can plant 'nitrogen fixing' plants which encourage a bacteria known as Rhizobium to take nitrogen from the air and store it in the plant's roots. Peas and beans are common plants for this purpose.
You can also purchase fertilising chemicals with high Nitrogen content to treat your soil before and during planting .
one example: when animals die there bodies decompose. This decomposition returns nitrogen to the soil.
Nitrogen is put into the soil by the air having nitrogen naturally in it, animals waste, and the plants put nitrogen in the soil
Farmers apply fertilizers to the soil which replaces the nitrogen with its nutrients

Why do farmers put nitrates in soil?
Farmers add nitrates to soil in the form of fertilizers to provide essential nitrogen for plant growth. Nitrogen is a crucial nutrient for plants to thrive and produce healthy crops. Nitrogen helps in the formation of proteins, chlorophyll, and other vital components necessary for plant growth and development.
What is applied to replace soil nitrogen crop fields?
Fertilizers containing nitrogen, such as ammonium nitrate or urea, are commonly applied to crop fields to replace soil nitrogen levels. These fertilizers provide plants with the necessary nutrients for growth and development. Additionally, crop rotation and planting legumes, which can fix atmospheric nitrogen into the soil, are other strategies used to replenish soil nitrogen.
How can a farmer protect the nitrogen content or soil?
Farmers can protect the nitrogen content in soil by practicing crop rotation, using cover crops, and reducing the amount of synthetic fertilizers applied. These practices help to maintain a healthy nitrogen balance in the soil, which is essential for plant growth and soil fertility.
What are the different ways by nitrogen in the air reaches the soil?
Nitrogen in the air reaches the soil primarily through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen into a form that plants can use. Nitrogen can also reach the soil through precipitation, as nitrogen compounds are washed out of the atmosphere and deposited onto the soil surface. Additionally, nitrogen can enter the soil through the decomposition of organic matter, releasing nitrogen back into the soil as plant nutrients.
How is deposition helpful to farmers?
Deposition helps farmers by providing essential nutrients, such as nitrogen and sulfur, to the soil. These nutrients are necessary for plant growth and crop productivity. Deposition can also improve soil structure, water retention, and overall fertility, benefiting agricultural activities.
What do farmers apply to land or soil to increase nitrogen?
They can either a) spread a nitrogen based fertilizer, or b) rotate to a crop that replaces the nitrogen in the soil.
Why farmers prefer to grow bean and peas in nitrogen deficent soil?
They are capable of converting atmospheric nitrogen into nitrogen that can be used by plants. They make the soil better.
Are Decomposing bacteria and nitrogen-converting bacteria important to farmers?
Decomposing bacteria and nitrogen-converting bacteria important to farmers because they help to send nutrients through the soil. These types of bacteria regulate nitrogen n the soil.
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 must farmers add nitrogen to the soil?
Farmers add nitrogen to the soil because it is an essential nutrient for plant growth. Nitrogen is a key component of chlorophyll, which is necessary for photosynthesis and overall plant development. Adding nitrogen helps improve crop yields and promote healthy plant growth.
How does crop rotation help restore nitrogen in soil?
well, by rotating the fields, the farmers give the soil a chance to naturally restore nitrogen and other nutrients.
Why must farmers continually add nitrogen when the element recycles naturally?
Farmers need to add nitrogen because crops remove it from the soil faster than it can be replenished through natural processes. While nitrogen does recycle naturally through processes like decomposition and plant uptake, the rate at which crops deplete the soil of nitrogen often exceeds the rate of natural recycling. This is why farmers supplement the soil with nitrogen through fertilizers to maintain optimal growing conditions for their crops.
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

Why must farmers constantly and nitrogen when this element recycles naturally?
Farmers need to constantly add nitrogen to their fields because crops remove nitrogen from the soil as they grow. While nitrogen does cycle naturally through processes like nitrogen fixation and decomposition, the rate at which crops deplete nitrogen often outpaces natural recycling, leading to nutrient depletion in the soil. By adding nitrogen through fertilizers, farmers ensure that their crops have an adequate supply for optimal growth.
