FirsTurf Liquid Slow Release Fertiliser Range
N-Sure 28-0-0 Trisert KS 15-0-12

Headland’s range of liquid slow release fertilisers contain a slow release nitrogen source – Triazone – that is well proven in the UK climate.

The idea of a slow release nitrogen source may, at first, seem a contradiction in terms, but Triazone, with its unique ring structure, binds to soil particles and organic matter and is then slowly broken down, releasing its nitrogen over a 4 – 8 week period, depending on the properties of the rootzone.

Less flush = lower clipping yield



Headland N-Sure 28-0-0 and Trisert KS 15-0-12 both contain significant levels of Triazone and therefore display the unique benefits illustrated in our graphs. Headland Liquid Fertilisers containing Triazone have an inherently lower scorch risk compared to other liquid and soluble fertilisers.

This means that watering-in of Triazone based products is not necessary from a safety angle – unlike many other liquid fertilisers which may require supplementary irrigation. The slow release properties of Triazone provide gradual nitrogen availability to the plant, reducing the amount of clippings produced and providing even growth characteristics – even when comparatively large amounts of nutrients are applied.

Where to use FirsTurf

FirsTurf Liquid Fertilisers are suitable for use on all turfed areas including golf and bowling greens, tees, approaches, surrounds, fairways, winter season pitches, cricket outfields and domestic lawns.

Tank mixing FirsTurf liquid Fertilisers

Tank mixing is an ideal method of saving labour and fine tuning fertiliser applications. Headland has developed a number of tank mix recommendations to further enhance performance. These include combining with water soluble fertilisers to initiate a faster response at low soil temperatures or utilising a tank mix with Headland ProTurf – liquid iron for enhanced colour on the run-up to a tournament. Details of tank mix combinations are available on request from Headland.
