What is the purpose of a deflector shield in fertilizer application?

The purpose of a deflector shield in fertilizer application is to direct fertilizer to one side of the rotary spreader. By using a deflector shield, applicators can control the spread pattern and ensure that the fertilizer reaches specific areas, which is particularly useful when applying along edges, fences, or near sensitive areas like water bodies. This targeted application minimizes the likelihood of fertilizer being spread where it is not needed and helps in achieving precise coverage.

The design and placement of the deflector shield allow for a more controlled application, which can lead to better nutrient management, reduced environmental impact, and more efficient use of fertilizers. This is crucial for promoting plant health and optimizing crop yields while ensuring that excess fertilizer does not contribute to runoff or other environmental issues.
