A batsman and wicketkeeper on a grass cricket ground in London

The outfield is madeunderneath.

Most days lost at a cricket ground are lost to the outfield, not the square. Pitch & Course builds the soil under the outfield so rain goes in, the ground is fit to field on sooner, and a dry August does not leave it brown and cracked. One pass a year, at the end of season 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.

The square gets the attention. The outfield loses the days.

A square under covers can be dry and ready while the outfield is unplayable. Soft, slow outfields, wet ends, worn run-ups and boundary edges, and a clay outfield that cracks open in August. They are all soil problems, and the outfield is too big to fix by hand.

Days lost to a wet outfield

Compacted topsoil takes water slowly, so it sits, and the umpires call it unfit to field. Drainage only helps with the water that reaches it.

Worn ends and run-ups

Shallow roots give way where the bowlers run and the fielders turn. Deeper roots hold those areas together and grow back between matches.

August

Soil with little humus dries fast and holds little. Humus holds water where the roots are, so the outfield stays green and does not open up in cracks.

Outfield first. A square is rolled clay loam built for pace and bounce, a different construction from the outfield, so the plan starts on the outfield, where the days are lost. A practice strip is its own order, planned with you.
A ground is judged on its square. Its season is decided by its outfield.

What the biology changes under an outfield

  • The structure opens. Humus made from thatch, clippings and old root binds on to clay to form crumbs. Water goes in and the excess drains, so the outfield is fit to field on sooner after rain. On a split trial, 100 mm of water went into the treated half in 235 seconds against about 27 minutes on the other.
  • The roots go deeper. Around the roots, the biology frees up phosphate and potash already in the soil but locked away, and the roots go down to reach it. On heavy clay, three annual applications took rooting from 35 cm to 95 cm.
  • The soil holds water where the roots are. Humus holds moisture through a dry spell, so the outfield comes through August green and the clay does not crack open.
  • It compounds. The biology establishes and keeps working, so the second season starts from where the first finished. Keep the autumn aeration: the biology builds the structure that aeration opens, so the relief lasts longer.
What it is. Not a fertiliser, not a biostimulant and not a plant protection product: it is the living biology of a healthy soil, and it works on the soil of the outfield. The square is a separate conversation.

On the track in Ireland since 2019

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.

Fairyhouse Racecourse, Co Meath

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.

What comes off the bill

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.

The annual inputs billToday

Press With Pitch & Course to see what changes. Press a line to read why.

Sand

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.

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.

Kinder to the ground, to the people on it, and to what lives around it

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.

For the water and the land

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.

For the people and animals on it

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.

For wildlife

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.

Season by season

The change is biological, so it builds year on year, and each season starts from where the last finished.

First season

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.

Second season

Structure opens through the topsoil and a pit shows it. Wet and dry weeks move the outfield less. The ends and run-ups recover faster.

Third season and on

Humus is built through the profile and the outfield holds itself. The routine stays the same: one pass a year, at the autumn renovation.

Measure it on half the outfield

Treat one half of the outfield, square to boundary, and leave the other half. The GMA toolkit already tells clubs to inspect the soil profile and root growth in the poorly drained areas, so the comparison is the inspection you were told to do, done on both halves.

  • A few cores from each half, before you start and at twelve months.
  • Time a ring of water going in on each half, on the same day.
  • Days lost or delayed to a wet outfield, and hours mowing and repairing, through the season.
  • The county pitch adviser’s view, before and after.

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 end of season renovation in September or October, after the outfield has been aerated and scarified and before the new seed closes over. The soil is still warm (SOBAC advises above 12°C for turf) and the ground is out of use, so the fortnight either side with nothing synthetic costs you no fixtures. It is the best natural window of any sport.

  • A club outfield is one and a half to two hectares. One pallet of 20 bags of 25 kg covers one hectare at 500 kg per hectare, so a full outfield takes two.
  • £1,000 plus VAT a pallet, which is £1,000 a hectare a year. Spare bags go on the practice ground or the nets outfield.
