Description
Carbamide (urea): nitrogen fertilizer. Characteristics and use
Carbamide (urea) is used in agriculture as fertilizer. Nitrogen is an essential nutrient for plants and plays a key role in their growth, development and protein production processes.
Carbamide contains a high percentage of nitrogen (about 46% by weight), making it an effective source for plants. Urea fertilization promotes sustainable plant growth over a long period of time.
The advantages of using urea include its good solubility in water and the absence of problems with the presence of other nutrients. It is widely used for feeding various crops, such as grains, vegetables, fruits and other plants.
Operating principle of carbamide (urea)
The principle of action of carbamide (urea) as a fertilizer is as follows:
- Dissolution in soil: Carbamide is easily soluble in water. When fertilizer is applied to the soil, it quickly dissolves to form a nutrient solution.
- Ammonia Formation: In soil, urea is decomposed by enzymes and microorganisms to form ammonia (NH3) and carbon dioxide (CO2).
- Conversion of ammonia to nitrates: Ammonia formed from urea undergoes a process of nitrification, in which it is oxidized by bacteria into nitrites (NO2-) and then into nitrates (NO3-). Nitrates are a form of nitrogen that plants can easily absorb.
- Uptake by Plants: Plants absorb nitrates from the soil through their roots and synthesize protein and other important organic compounds. It is a key element for growth, leaf formation, flowering and fruit formation.
- Gradual release of nitrogen: One of the advantages of carbamide is its ability to provide a gradual release of the substance over an extended period of time. This allows plants to receive essential nutrients as needed, promoting sustainable growth and development.
Carbamide or urea is used to feed all types of plants: both ornamental and vegetable. The use of carbamide is relevant for all types of soils. Urea is especially effective for irrigation and watering.
When and how to use carbamide (urea)
The use of carbamide (urea) as a fertilizer depends on the specific soil conditions, the type of crops grown, climatic conditions and other factors. Here are general recommendations:
- When to use:
- Spring: Carbamide is often applied to the soil in the spring before sowing or planting crops. This ensures nitrogen availability for plants during the initial stages of their growth.
- Autumn: In some cases, urea fertilizer can be applied in the fall to prepare the soil for the next season.
- Methods of application:
- Soil Application: Carbamide can be spread over the soil surface and incorporated into the soil using a plow or other mechanical means.
- Spraying: In some cases, urea can be applied as a solution when sprayed on plants. This method ensures rapid absorption.
- Dosage:
- The dosage of carbamide depends on the type of soil, the requirements of specific crops, climate and other factors. Dosage recommendations are usually listed on the fertilizer packaging or provided by local agricultural experts.
- Dosage division:
- It is recommended to divide the total dosage into several doses during the season. This promotes a more even supply of nutrients and prevents overuse.
- Taking into account soil characteristics:
- Consider the nitrogen level in the soil and the specific requirements of the crops being grown. Agricultural research and soil testing can help determine optimal doses.
- Cautions:
- Follow the fertilizer manufacturer’s recommendations.
- When using urea, it is important to avoid excessive doses. This can lead to negative consequences for the environment and plants.
- Carbamide cannot be used simultaneously with lime, chalk, or ash.
Before using carbamide, it is recommended to consult with local agronomists or soil specialists to determine optimal dosages and application methods based on the specific conditions of your region.
