What type of soil amendment is primarily used to provide essential nutrients?

Fertilizer is primarily used as a soil amendment to provide essential nutrients necessary for plant growth. It typically contains a mix of macronutrients like nitrogen, phosphorus, and potassium, which are crucial for various plant functions, including growth and development. The application of fertilizers helps enhance soil fertility, ensuring that plants receive the right balance of nutrients, which can improve crop yields and overall plant health.

While organic matter is beneficial for overall soil structure, water retention, and microbial activity, it may not always supply the concentrated nutrients that fertilizers can provide. Sand and clay, on the other hand, primarily influence soil texture and drainage properties rather than acting as nutrient sources.
