Nitrogen (N) and phosphorus (P) are essential nutrients for plant growth and development. However, too much N and P can be toxic to plants and hurt crops and animals. Analysis and assessment of N and P content in soil and crops will help build a balanced and effective fertilizer plan for agricultural production. This study introduces a new method to determine both TP and TN in one process, reducing the analytical cost and time. |
