Frequently Asked Questions

Why is high potassium important for turf?

Potassium strengthens turf cell walls, improving resistance to disease, drought, heat stress, and wear. It's the key nutrient for hardening turf heading into stressful conditions.

When is the best time to apply ProTurf Hi K?

Apply before periods of stress — late spring before summer heat, or late summer/autumn before winter. It's also ideal for high-traffic areas like sports fields year-round.

Is ProTurf Hi K suitable for golf courses and sports fields?

Absolutely — it's a professional-grade product used widely on golf courses, sports fields, and commercial turf applications across Australia.

Can I use ProTurf Hi K alongside other fertilisers?

Yes, but avoid overlapping with other controlled release products to prevent over-application. Always calculate total nutrient load across all products being used.

What's the difference between ProTurf Hi K and ProTurf NPK?

Hi K has significantly more potassium (16.6% vs 12.4%) and less nitrogen (12% vs 15%), making it better suited for stress hardening rather than general growth promotion.
