Incitec Pivot CK 88 Fertiliser 25kg

Product Description

What is CK 88?

CK 88 is a balanced NPKS fertiliser from Incitec Pivot — one of Australia’s most trusted fertiliser manufacturers. With a high nitrogen base plus phosphorus, potassium and sulfur, it’s a reliable all-round feed for summer-active lawns and turf, and equally at home on vegetable, forage and row crops.

Who it’s for

Lawns & turf: couch, kikuyu and other warm-season grasses that do their growing through the warmer months.
Sports grounds & playing fields: keeps high-traffic turf green and recovering.
Growers: veg, forage and row crops on alluvial soils with a high phosphorus status.

Why it works

The nitrogen drives leaf growth and colour, potassium builds stress and wear tolerance, sulfur supports protein and chlorophyll production, and the measured phosphorus suits soils that already hold good P reserves. The result is steady, even growth rather than a quick flush that fades.

Broadacre / crops: approx. 300kg per hectare.

Frequency: apply 3× a year — March, September and December. Reduce frequency through winter when warm-season growth slows. For over-sown winter fields, a winter application can help.

Always water in thoroughly straight after spreading so nutrients move into the soil.

Tips for use

Best suited to summer-active grasses like couch and kikuyu.
Spread evenly — a broadcast/drop spreader gives the most consistent result and avoids streaking.
Water in immediately after application.
Do not apply as a liquid through irrigation, and do not use as a stockfeed supplement.
Apply to dry foliage and avoid spreading right before heavy rain to reduce run-off.
