Kunstmest, or synthetic fertilizer, is a man-made substance used to enhance soil fertility and promote plant growth. It typically contains essential nutrients like nitrogen, phosphorus, and potassium, which are vital for healthy crop development. Farmers often apply kunstmest to increase agricultural productivity and ensure a reliable food supply. The use of kunstmest has revolutionized modern agriculture, allowing for higher yields and more efficient farming practices. However, its overuse can lead to environmental issues, such as soil degradation and water pollution. Sustainable practices, including crop rotation and organic fertilizers, are being explored to mitigate these negative effects.
