The active ingredient in fertilizer typically refers to the key nutrients that promote plant growth, primarily nitrogen (N), phosphorus (P), and potassium (K). These nutrients are often indicated in a fertilizer's N-P-K ratio on the packaging. Additionally, some fertilizers may contain secondary nutrients like calcium, magnesium, and sulfur, as well as micronutrients essential for plant health.
