Fertilizer is primarily made of a combination of nutrients essential for plant growth, most notably nitrogen, phosphorus, and potassium.
Fertilizers are designed to supplement the natural nutrients found in the soil, promoting healthier and more productive plant life. The composition of fertilizer varies depending on the specific needs of the plants it is intended for.
Key Components of Fertilizer
The main components are often represented by three numbers on fertilizer packaging, such as 4-7-6, indicating the percentage (by weight) of each nutrient. These nutrients play crucial roles:
- Nitrogen (N): Essential for leaf and stem growth and gives plants their green color.
- Phosphorus (P): Supports root development, flowering, and fruit production.
- Potassium (K): Enhances overall plant health, disease resistance, and tolerance to environmental stressors.
Here's a table summarizing the main nutrients in fertilizer:
| Nutrient | Symbol | Role in Plant Growth |
|---|---|---|
| Nitrogen | N | Promotes leaf and stem growth; responsible for the green color of plants. |
| Phosphorus | P | Supports root development, flowering, and fruit production. |
| Potassium | K | Enhances overall plant health, disease resistance, and tolerance to environmental stressors (e.g., drought, cold). |
