The routine addition of further sand to bowls greens has led to a method of reactive greenkeeping where we wait for negative symptoms to arise and then treat them. This has created a thankless job for many greenkeepers, where they are constantly having to be vigilant for a host of weeds, diseases and disorders before deciding which pesticide to use. The inert nature of the soils that this system creates means to to get any reaction form the turf in terms of growth, it is usually essential to continually apply chemically derived, strong fertilisers, which themselves help perpetuate the problems due to the high salt content of the minerals used in their manufacture.
The future, however, is bright for those who recognise the folly of this approach and accept that there is already too much sand in their green. They know that some semblance of life needs to be returned to the soil. If you’ve read Performance Bowling Greens, you will of course know that bringing a club around to this way of thinking can be difficult. Clubs are usually not very patient in waiting for results and 40 or 50 years of sand top dressing does things to the soil that are not easily reversed, but reversed they can be and that has been my goal since I started out in greenkeeping.
To that end, I have studied soil science and developed methods of helping greenkeepers to improve their soil to enable the development of fine perennial turf that becomes easier and more economical to maintain, but of course these methods take time. Over the time that I have been doing this, we have moved to a point where more of the industry that supplies the greenkeeping sector are realising that they need to listen to greenkeepers and develop products and materials that help with this transitional process.
To that end I’ve recently added some new materials to the Bowls Central Shop to help further the invigoration of inert soil. One of the latest of these is ProLong 12.0.15 Fertiliser.
ProloNg® nitrogen efficiency technology in a high quality, homogenous, mini granular fertiliser range, specifically formulated for high quality fine turf.
- Low salt formulations
- Especially formulated to encourage and maintain healthy root zones, looking after the biota
- 100% of nitrogen is treated with ProloNg® technology
- Safe to use throughout the year
75% of nitrogen (N) as ammonium with ProloNg® technology
25% of nitrogen (N) as urea with ProloNg® technology
100% of potash from potassium sulphate
Potential longevity in spring/summer application, 8-10 weeks; autumn; winter application, 4-5 months, based on recommended application rates. Longevities and are purely a guide, as plant variety and density, environmental conditions and timing of application will dictate nitrogen use and therefore the speed in which applied nitrogen is utilised.
Nutrients applied per m² @ 50g/m²
6g N – 7.5g K₂O + 1.5g MgO + 2g CaO + 3g SO₃ + 0.5g Fe
1-2.5mm granules
Application Guide: apply at 50g/m2 , 3 bags per application for an average sized bowling green
