1. Urea (Chemical Compound)

Urea is an organic compound with the chemical formula CO(NH₂)₂. It is a key nitrogen-containing substance that is produced naturally in the liver of mammals as part of the urea cycle. Here are some details about it:

Chemical Formula: CO(NH₂)₂
Common Uses:

• Urea is widely used as a fertilizer in agriculture because it is rich in nitrogen, which is essential for plant growth.
• It is also used in the production of plastics (like urea-formaldehyde), and in some pharmaceuticals, cosmetics, and glues.
• In the body, urea helps to remove excess nitrogen and is excreted in urine.

2. UREA in Agriculture

In agriculture, "urea" is often referred to as a type of nitrogen fertilizer. It is the most commonly used nitrogen fertilizer worldwide because of its high nitrogen content (about 46%). It plays a vital role in plant nutrition and soil fertility.
It is typically spread onto fields or dissolved in water and sprayed onto crops. Once in the soil, it reacts with water and is converted into ammonium and nitrate, forms that plants can easily absorb.

3. Urea Cycle (Biology)

The urea cycle is a series of biochemical reactions in the liver where ammonia, a toxic byproduct of amino acid breakdown, is converted into urea. Urea is then excreted in urine by the kidneys. This cycle is crucial for detoxifying ammonia in the body.
