Fertilizers for plants are special products that are used to improve soil fertility and provide plants with the necessary nutrients. They contain various macro- and microelements, such as nitrogen, phosphorus, potassium, iron and others, which are key to healthy plant growth and development. Fertilizers can be organic, obtained from animal or plant sources, or mineral, produced artificially. They can be used both in agriculture to increase yields, and in horticulture to improve flowering and plant growth. Proper application of fertilizers can help create optimal conditions for plants and increase their resistance to diseases and pests.
