A golf course is played twelve months of the year on soil that never gets a rest. Pitch & Course builds the soil under the fairways, tees and surrounds so rain goes in instead of lying on top, the walk-offs and tee tops root back, and a dry summer does not leave the fairways brown. One pass a year, at the autumn renovation, with the spreader you already have.
20 bags of 25 kg, spread once a year at 500 kg per hectare with a standard spreader. Delivery quoted at order.
Fairways that lie wet from November to March, trolley bans and course closed days, tee tops and walk-offs worn to bare ground, and fairways that brown off in the first dry fortnight of summer. They look like grass problems. They are soil problems, and a course is too big to fix by hand.
Compacted topsoil takes water slowly, so it lies on the surface, the course closes or goes to trolley bans, and members notice. Drainage only helps with the water that reaches it.
Shallow, thin roots give way where every player stands and walks. Deeper roots hold those areas together and grow back between competitions.
Soil with little humus dries fast and holds little. Humus holds water where the roots are, so the fairways stay green through a dry spell and the irrigation you have goes further.
Two Irish racecourses have had Bacteriosol under the racing surface and the parade ring since 2019, and both have extended the area every year. Their managers have put on the record what they saw: deeper roots, a sod that recovers faster after racing, and ground that drains.
Started on the parade ring and a small piece of track that was proving difficult for sod depth and water retention, monitored with the course's track advisor, and extended every year since. By 2023 it covered about a quarter of the racing surface.
We have found that the roots system has increased year on year and has led to improved sod strength, quality and density. The biggest return we have made for our investment is seeing the sod under foot recovering quicker than before after each race meeting, and ultimately leading to a safer racing surface.
The walk in to the parade ring lay wet and soggy after any overnight rain and had to be cordoned off on race days. Three years after the first application it was filmed the morning after a stormy night with 10 to 15 mm of rain, and the manager said it was “making our job so much easier to bring areas literally back to life”.
After a very, very wet night we have practically dry soil, meaning that the drainage in the area is just fantastic.
Their words, on the record, from two courses that started small and now treat more ground every year. Every order comes with the record sheet, so your ground joins the record.
Sand, synthetic phosphate and potash, and a good part of the nitrogen are bought to do what a living soil does on its own. Water comes down with them.

Half the sand on established turf. Sand is bought to open a tight surface and dilute thatch. The biology turns thatch into humus and builds the crumb structure that sand was standing in for, so the dressing halves. Keep what you use for levelling.
No synthetic phosphate or potash. Most turf soils hold years of both, locked up where roots cannot use it. The biology unlocks it around the roots, so the synthetic bag comes off. That is the SOBAC plan, and it is the plan that runs on more than 300,000 hectares.
40 per cent less bought nitrogen. Organisms at the surface take nitrogen from the air and the humus releases what it holds, so the sward is fed from the soil instead of the bag.
Less water to keep it green, and here is what was measured. On a split trial, 100 mm of water went into treated ground in 235 seconds against about 27 minutes untreated, so rain and irrigation reach the roots instead of running off. Roots went from 35 cm to 95 cm on heavy clay, so the sward draws on water it could not reach before. Humus holds water where the roots are.
The sand, phosphate and potash and nitrogen figures are the SOBAC plan for established turf, the plan that runs on more than 300,000 hectares. The water figures were measured in soil pits on Warwickshire clay and in a split trial in Brittany. The record sheet that comes with every order adds your ground to that record.
A living soil needs less put on it. That is better for the water that leaves the ground, for the players and horses on the surface, and for the wildlife at the edges.
What you do not spread cannot wash off. Less bought nitrogen, no synthetic phosphate or potash and half the sand hauled in means less leaving the ground in drainage water and fewer lorries on the drive. The humus it builds is carbon held in the soil.
Bacteriosol is naturally occurring soil biology on a plant and mineral base, non-toxic and non-pathogenic. The surface can be used as soon as the granules have gone in, and the players, horses and grounds staff are on ground that gets fewer synthetic inputs each season.
A soil that is alive underneath feeds everything above it, the insects and the birds that work a pitch or a course at first light. Less synthetic input reaches the margins, the hedges and the water's edge.
The change is biological, so it builds year on year, and each season starts from where the last finished.
The biology establishes and the first gains are below the surface, where a core shows them: root depth and density, and how fast a ring of water goes in.
Structure opens through the topsoil and a pit shows it. Wet and dry weeks move the fairways less. Tee tops and walk-offs recover faster.
Humus is built through the profile and the fairways hold themselves. The routine stays the same: one pass a year, at the autumn renovation.
Treat the fairways and tees on one loop of holes and leave a matching loop on the same soil untreated. Nine against nine, or three against three. That is the whole comparison, and it is one a greens committee or a course manager can read in a minute.
A one page record sheet comes with the order. A baseline soil profile, dug and read before the first application, is a priced extra: ask when you order.
When it goes on. The autumn renovation in September or October, after the fairways and tees have been aerated and before growth slows. The soil is still warm (SOBAC advises above 12°C for turf) and the fortnight either side with nothing synthetic falls when fairways get little anyway. Spring, once the soil has warmed, is the second window.
