What is one important reason to keep records of fertilizer application?

Keeping records of fertilizer application is crucial for preventing runoff and groundwater contamination. When fertilizers are applied, there is always a risk that excess nutrients can be washed away into water bodies during rainfall or irrigation. By maintaining accurate records of when, where, and how much fertilizer is applied, farmers and agronomists can better manage the timing and quantity of their applications to align with crop needs and minimize environmental impact. This practice not only supports sustainable farming but also helps in adhering to best management practices aimed at protecting water resources.

While there are other valid reasons for keeping records, such as meeting legal requirements, comparing costs, or managing storage inventory, the primary focus of record-keeping in this context is to ensure environmental protection and sustainable agricultural practices.
