Fertilizer analysis refers to the process of determining the nutrient content of fertilizers. This analysis typically focuses on three primary nutrients: nitrogen (N), phosphorus (P), and potassium (K), often represented as a series of three numbers on the fertilizer package. For example, a fertilizer labeled as 10-20-10 contains 10% nitrogen, 20% phosphorus, and 10% potassium. The results of fertilizer analysis help gardeners and farmers choose the right product for their plants' needs. By understanding the nutrient composition, they can apply the appropriate amount of fertilizer to promote healthy growth and maximize crop yields.
