The Pre-Lay Checklist: Soil Testing and Preparation Requirements for Commercial Turf Success in Victoria

We are more than just the suppliers of high quality, Victorian-grown grass at Instant Turf Melbourne. We collaborate with the industry players to be sure that all installations are founded on a strong background that will facilitate a long-term performance. Planned pre-lay approach is vital towards smooth, sustainable outcomes in any size of the site.

The Foundation: Foundation Soil Testing.

The soil conditions in Victoria are diverse. The sodic loams of the northern growth areas of Melbourne are heavy as compared to the well-drained sandy loams found in the southeast. The assumption of suitability may make a project risky. Thus, commercial turf installation begins with professional soil testing.

The soils must have a pH of between 6-7 in order to develop powerful root systems by turf. Tests in soil also show the presence of a clay content and deficiencies of nutrients that cannot be observed on the surface. Gypsum is necessary where there is a lot of clay- and this is prevalent across Victoria. In its absence, the ability to penetrate is hampered due to compaction of clay, which makes it difficult to drain, and the water on the surface is likely to stagnate and the result is the death of the turf in a few weeks.

Sub-Base Preparation and Soils Amending.

After the testing is completed, concentrate on the physical preparation of the site. In commercial works, the subsoil is normally compacted by the heavy machinery traffic. A shallow surface rake does not suffice. The plowing of a hoe or cultivator down 100-150 mm is better than aerating and allows new roots to incorporate with the sub-base.

We suggest that at least 100mm of high quality sandy loam be added to ensure maximum performance. This material is also good in Melbourne weather, as it has good drainage throughout the winter season and it is not too soft to sustain heavy foot traffic.

Finished and Accurate Grading.

Accurate grading is essential in and around the hardscape areas like paths, kerbs, and driveways and the edges of the garden. This is to prepare soil approximately 30mm underneath surrounding finished surfaces to suit the thickness of the turf slab. This gives a smooth surface that eliminates falls and the safety requirements of the people and business premises.

Fertiliser and Wetting Agents: Starter Fertiliser.

Treat the base with a good quality starter fertiliser before the turf delivery. In Instant Turf Melbourne, we suggest a slow releasing mix that has a high amount of phosphorus in order to accelerate the growth of roots. It can be most useful in warmer weather, particularly in a Victorian summer, to apply a wetting agent. It assists in maintaining turf moisture in root zone to promote the health of the turf in the first 14 days after it is installed.
