Fertilizer soil refers to soil that has been enriched with nutrients to promote plant growth. This enrichment is typically achieved by adding various types of fertilizers, which can be organic, like compost or manure, or synthetic, like ammonium nitrate. The added nutrients, such as nitrogen, phosphorus, and potassium, help improve soil fertility and support healthy plant development. Using fertilizer soil can enhance crop yields and improve the quality of fruits and vegetables. However, it is essential to apply fertilizers correctly to avoid over-fertilization, which can lead to nutrient runoff and environmental issues, such as water pollution in nearby rivers and lakes.
