Why drop spreaders aren’t suitable for CRFs

Drop spreaders are known for their precision in applying granular products.

However, they pose significant challenges when used with controlled release fertilisers due to one primary issue: coating damage.

Coating damage

The effectiveness of controlled release fertilisers relies on the integrity of their specialised coatings.

Drop spreaders can damage these coatings through the agitation and pressure exerted during the spreading process. This mechanical damage to the fertiliser coating can lead to a premature and uneven release of nutrients, negating the benefits of controlled release technology.

Uneven nutrient distribution

Damaged coatings result in uneven nutrient release, causing patchy turf growth.

This creates areas of both over-fertilised and under-fertilised turf, compromising the uniformity and overall health of the turf.

Conclusion

In summary, using drop spreaders for controlled release fertilisers can compromise their effectiveness, increase maintenance costs, and pose environmental risks due to coating damage.
