Ground Maintenance FSM
Nitrate nitrogen is a useful tool in spring as it will offer early spring growth and surface recovery even when soil temperatures are low. Granular Cold Start technologies, such as OAS Cold Start 10-2-20 and OAS Cold Start Boost 11-5-5, are specially formulated to kickstart turf even in the coldest of springs. Alongside granular fertiliser, there are also Cold Start liquids, such as OAS Rapid Response12-0-0. These will improve colour, sward density and turf quality, improving the overall aesthetics of your surfaces.
In addition to nitrogen, turfgrass requires other macro and micronutrients, such as phosphorus and potassium. As the plant grows, it will take nutrients from the soil through the root system to grow healthy. Before applying fertiliser, it is important to test the soil for its nutrient availability levels. This will allow you to build a fertiliser programme to maximise plant health and minimise over-application of nutrients that could pollute the environment.
When recovering high-wear areas during the winter months, consider using tetraploid ryegrass, such as R140 and 4Tetra, from the OAS R-Range grass seed. Tetraploids germinate and establish faster than diploid ryegrass, even in cold soil temperatures from just 4o
c. Additionally, pre-
germinating seed speeds up the germination process, as the seed will have already begun to chit before you apply it to the ground.
To summarise, Nitrate and ammonium-based fertiliser are available to the plant in cold conditions. Using controlled-release
resin-coated technologies that
incorporate nitrates will control the release of nitrogen to the plant as well as reduce the risk of pollution. Using tetraploid ryegrass, fertilisers, and germination sheets will enhance recovery and sward density.

When applying fertilisers and seed in winter the use of germination sheets will improve recovery of the existing sward and support the establishment of the new seed. The germination sheets themselves are also a deterrent to people wanting to play in that area. You need to be aware that restricting light to growing plants in spring can slow recovery if the sheets are left in place for too long. They can also create a microclimate that can encourage diseases such as Microdochium Patch.
