The Xtend CRF 15:2:20 fertiliser is a high-performance controlled release fertiliser designed to support strong, healthy turf growth. Using dual-technology formulation, it delivers a consistent supply of nutrient exactly when the plant needs it, helping turf maintain strength, density and colour throughout the season.
This unique blend combines temperature-primed release technology with inhibited nitrogen, creating a true controlled release pattern. The result is a quick initial response followed by an even release of nutrient over a three-month period. Its well-balanced analysis and high level of controlled release nitrogen mean that when it’s applied in autumn, the fertiliser slows right down over winter and then starts releasing again in spring. This helps support the turf through the colder months and gives it a boost as growth picks back up.
Engineered with environmental performance in mind, Xtend CRF 15:2:20 reduces the risk of nitrogen loss and improves overall nutrient efficiency. With its stable release profile and reliable granule behaviour in varying weather conditions, it offers a dependable choice for turf managers seeking consistent results with fewer applications.
Key benefits include:
Available in 20kg bags.

Characteristics
Xtend CRF 15:2:20 delivers a true controlled release of nutrient using a combination of temperature-responsive coated granules and inhibited nitrogen. This provides a fast initial turf response followed by a steady release of nutrient for up to three months. The coating slows right down in colder conditions and becomes active again as temperatures rise, helping support turf through winter and into spring.
Protect Technology
ProTect is a temperature-released coating technology developed within the Origin group. It responds to the plant’s natural need for nitrogen, offering a consistent release pattern even during prolonged wet weather. Its flexible structure protects the nutrient core, helping improve nitrogen efficiency and ensuring reliable performance across changing conditions.
Inhibited Nitrogen
The nitrogen inhibitors used in Xtend CRF slow down the availability of nitrogen, extending the longevity of each application. This reduces the risk of volatilisation and denitrification and complements the ProTect coating to deliver a controlled, phased release over three months with improved environmental efficiency.
The Xtend range uses NBPT to limit nitrogen loss to the atmosphere and DCD to slow the conversion of ammonium to nitrate in the soil. This allows ammonium nitrogen to bind more effectively to clay and organic matter, supporting better nutrient retention and a more efficient release to the plant.

Delivery
We are pleased to offer nationwide delivery, with the exception of Ireland, the Highlands, and the Islands. Our standard all-day delivery option is free for retail consumers. Should you prefer a morning delivery to provide more time, we offer an AM delivery slot for just £10. For trade pricing on products and delivery, please contact us directly.

To facilitate efficient unloading, a flat, level, concrete surface, or similar firm surface is necessary for the trucks to operate effectively. We cannot offload onto a gravel drive for example.
When you go through to the checkout we do have a notes section for you to request a specific date for delivery. Alternatively we will call you once we receive your order to discuss a suitable delivery date.
Seed products and TerraCottem are sent via DPD and we aim to send your order within 1 – 2 working days after receiving it.
For more detailed information on our delivery process, please visit our FAQ section. We also have a video on YouTube showing the delivery process so you can see what to expect on the day, take a look at the video below.

Our bulk products (turf, topsoil, bark) are delivered on square wooden pallets overnight and are offloaded using a hydraulic tail lift and manual pallet truck. These trucks require a flat, level, concrete or similar firm surface for operation. The pallet size is 1.2 metres X 1.2 metres.
Deliveries are scheduled Tuesday through Friday on an all-day delivery slot of 9am-5pm. The driver should give you a call when they are an hour away from the property.
Our pallet deliveries involve using a hydraulic tail-lift and pallet truck, which cannot lift over hedges or fences. Delivery is made to ground level only on a hard surface. If you do not have a hard standing surface for us to leave the pallet the delivery will be left kerbside.
Yes, we require advance notice to cancel or reschedule deliveries. Please contact us for specific details.

We do ask for a minimum of 24 hours’ notice if you want to collect turf from our office in Wilberfoss. If you do need the turf more urgently, we can arrange for you to collect the turf from the field, however please note this may not be in Wilberfoss. Full directions will be provided when you call to place the order as the location may vary depending on the filed we are working in.
The maximum amount of turf we can bring back each day is 120 square metres, this will obviously depend on the day if we have other orders in as to the amount we can allocate. If you do need more turf you can collect this direct from the field.

Inturf Classic is generally suitable for most applications. We do also have our RTF turf a durable and low maintenance turf and our Masters turf which is best suited for golf courses. We recommend discussing your specific needs with us for tailored advice.
For guidance on turf quantity, please provide us with the dimensions of the area you wish to turf, and we can assist in calculating your requirements.
Turf should ideally be laid as soon as possible after delivery, especially during the summer months (April to September), to ensure optimal freshness and health. If turf is left rolled up in the heat it can sustain turf heating.
Immediately after installation, turf should be watered thoroughly, both in the morning and evening, for approximately one hour each time, for a period of 28 days unless there is significant rainfall. Read our blog on ‘Watering newly laid turf’ for more information.
It is recommended to lay the turf as soon as it is delivered, particularly during warmer months, to prevent drying out and ensure successful establishment.
We supply Melcourt blended loam topsoil which is fully compliant with British Standard 3882:2015 ‘Multipurpose Grade’. It’s carefully manufactured, high-quality soil, consisting of sandy loam and organic matter.
We have two bark products available both supplied by Melcourt, a leading supplier of peat-free compost, mulches and soil improvers. Our Playbark is most suited for play areas where you need a safe, durable and natural bark option. The Ornamental Bark Mulch is more of a decorative bark for gardens, flower beds, pathways and car park borders to give a few examples.
