Sustainable and all of the other buzzwords “WRAP-ped” up. Andy Law of Whitemoss Eco explains the workings and benefits of green compost


AS someone who has been involved with golf courses in excess of twenty years, I well remember “composts” being used in the maintenance practices of many greenkeepers and groundsmen.

One of my first ever customers, when I was a rep for Maxwell Hart in Yorkshire, had his staff producing over a 100 tonnes of their own greens dressings using their own compost. These were generally derived from cores, a little rotting grass, hay, tea leaves and various other organic matter. Compost was very much a DIY operation that produced “unstable” high nitrogen organic material that often still contained harmful pathogens likely to cause turf disease and future fungal attacks!

Unstable composts also tend to draw nutrients away from the surface they are applied to, as they are still in the feeding stage; therefore, rather than adding benefits, they had the opposite effect. The only benefit was that they were considered cheaper than buying a proprietary pre-blended topdressing.


The difference now is that, like most things in the 21st century, strict regulation has come to force and, in the case of green compost, it has enabled producers to move certain composts from a “waste” material to a fully certified top quality organic amendment. The certification process is in place to ensure that the raw stock produces a consistent finished product, batch after batch, week after week, year after year.


The secret to producing a first class green compost is to achieve, and maintain, a core temperature in the windrow of at least 150O


C for a minimum of


18-21 consecutive days. In the ‘good old days’, good green composts would take up to twelve months to produce. Now, with modern machinery and more refined techniques, a better product can be turned around in twelve to fourteen weeks.


Composting to pas100/2005 standard reduces bacterial and viral pathogens to non- detectable levels, and it has been demonstrated that viruses do not regrow after thermal de- activation.
