Nitrogen (N), phosphorus (P) and potassium (K) are the main macronutrients that play a key role in plant growth. They form the basis of fertilizers known as NPK fertilizers. However, in addition to these elements, there are many other fertilizers:

1. Nitrogen fertilizers
Nitrogen is one of the most important macronutrients for plants, as it promotes the growth and development of green mass (leaves, stems). Nitrogen stimulates the formation of chlorophyll, which is involved in the process of photosynthesis. Lack of nitrogen leads to slower growth, yellowing of leaves.

2. Phosphorus fertilizers
Phosphorus plays an important role in the process of root formation, the development of flowers and fruits. This fertilizer helps plants at all stages of their growth, especially during flowering and fruit ovaries. The lack of phosphorus slows down the growth of the root system and worsens flowering.

3. Potash fertilizers
Potassium is necessary for plants to synthesize carbohydrates, proteins and fiber, as well as to strengthen cell walls. This is an important element for increasing plant resistance to diseases, drought and frost. A lack of potassium can lead to weak growth, reduced fruit quality and yield.

4. Trace elements
In addition to the basic macronutrients, plants need trace elements that play an important role in their metabolism and growth. They are required in very small quantities, but their deficiency can significantly affect plant health.

5. Organic fertilizers
Organic fertilizers are natural sources of nutrients for plants and affect the improvement of soil structure, its moisture retention capacity and microorganisms in the soil.

6. Mixed fertilizers (complex fertilizers)
Complex fertilizers contain several nutrients at once, which makes them convenient for use at various stages of plant growth. They can include both macro- and microelements.

7. Special fertilizers for individual crops
Some fertilizers are specifically designed to meet the needs of certain plants, such as vegetables, fruits, berries, or even lawns and ornamental plants.

8. Growth stimulants
Some substances help to improve the metabolism of plants and accelerate their growth. These substances can be synthetic or natural.
