Turf Industry Standard
Lindum has a standard for good quality turf for use in general landscaping which exceeds the industry minimum standard.
Properties of turf meeting the Lindum quality standard:
- Dimensions – Lindum turf is sold in 1 square metre rolls measuring 610mm x 1640mm or in big rolls of varying dimensions.
- General health – the turf will be a healthy colour and not visibly affected by disease or pests.
- Soil Classification – the turf is grown on a sandy loam soil.
- Grasses – all grass cultivars used in Lindum turf products are listed in the current edition of ‘Turfgrass seed’ produced by the Sports Turf Research Institute. The cultivars are declared and should occupy at least 98% of each turf. Species composition is carried out using an optical point quadrat.
- Cutting heights – the height of the sward will not exceed 25mm at time of harvest.
- Thatch – the thickness of uncompressed thatch will not exceed 10mm.
- Thickness of soil – the soil layer beneath the thatch will be a uniform thickness of between 5 and 15mm.
- Netting - netting is not used in Lindum Turf production.
- Strength – to demonstrate strength, 15 out of 20 rolls lifted off the ground by their shortest side will remain intact.
- Weight – rolls of 1 square metre in area will weigh less than 20kg unless it is very wet due to rain at time of harvest when the weight will be declared.
Lindum Higher Sports Turf Standard
The Lindum Higher Sports Turf Standard (HSTS) has been developed as a benchmark for use by specifiers/architects, consultants and contractors within the sports turf industry. The need for such a quality standard has arisen to complement the increasingly sophisticated design criteria for new sports turf surfaces.
The Lindum HSTS gives confidence to the user that the highest standards have been adhered to in the production process.
Buyers and specifiers of the Lindum HSTS can be reassured that the turf has been independently assessed shortly before delivery.
Cultivars of turfgrass use for sportsturf production are selected from the current edition of Turfgrass Seed according to suitability for purpose. Certificates of purity from the source seed houses can be supplied.
The Turf is to be composed of the sown turfgrasses, which should occupy at least 99% of each turf. Any other species present and their approximate % cover will be listed in the declaration. The botanical composition will be objectively assess with an optical point quadrat.
There will be no broad-leaved weeds in the sportsturf.
The sportsturf will be grown in an appropriate growing medium, according to end use. Where this is an imported rootzone the depth of rootzone will be sufficient to enable lifting of the turf without contamination from the indigenous soils below. The source of the imported rootzone will be identified, and a mechanical analysis will be supplied.
Where an imported rootzone is not specified, a suitable indigenous topsoil will be used as the growing medium. A particle size distribution analysis of the topsoil will be supplied.
The normal mowing height will be recorded on the declaration. The height of cut will be appropriate for the intended end use of the sportsturf.
The thickness of uncompressed thatch should not exceed 6mm unless specifically requested.
The sportsturf will be of sufficient maturity to remain intact when handled. However, where turf has been grown to order, the strength of the turf will be related to the amount of time from seeding to delivery.
General health of the turf
The sward will be of uniform appearance and will not be visibly affected by pests and disease.
If required, the turf will be independently assessed by a member of the Register of Independent Professional Turfgrass Agronomists (RIPTA) a maximum of two weeks before the first delivery of an order for sportsturf. The assessment will result in a declaration of Quality, with particular reference to botanical composition and general health.
The Declaration of Quality will describe the turf on the day of assessment. The client should be aware that, after delivery, the botanical composition and the health of the sward will depend on the subsequent management of the turf.
