ODOS Tech — Clover-Based Swards (Preview)

Forage & Pasture Management

Clover-Based Swards

Clover-based swards use nitrogen-fixing clover to supply some or all of a sward's nitrogen requirement, cutting how much synthetic fertiliser is needed.

01 · Context

How It Works

Clover draws nitrogen from the air and makes it available to the sward naturally, so the farm relies less on synthetic nitrogen.

Red clover is typically used in silage swards, where it can supply the full nitrogen requirement for silage production. White clover suits grazing swards, where it caps nitrogen need at a lower, but still meaningful, level.

Either clover can be established through a normal reseeding cycle.

02 · Emissions

Impact On Emissions

Clover-based swards cut direct and indirect nitrous oxide emissions from soil by reducing synthetic nitrogen on the reseeded area. They also cut the upstream emissions created when that fertiliser was manufactured.

Red clover in silage ground can remove synthetic nitrogen on that area entirely. White clover in grazing ground caps nitrogen use at a lower ceiling.

Your specific reduction, based on which clover type you use and how much of your platform is converted, is modelled precisely for your farm in the ODOS Tech platform.

03 · Production

Impact On Production

Clover-based swards can maintain or improve yields through biological nitrogen fixation. Where feed quality rises alongside it, animal performance may improve too.

Establishment does take time. A full season is typically needed after reseeding before the nitrogen benefit shows fully.

The fertiliser saving and the yield effect come from the same nitrogen the clover supplies.

04 · Costs

Cost & Economics

A one-time reseeding cost, with fertiliser savings over time.

The main cost is reseeding the ground with a clover-inclusive mix, a one-time cost per area converted. Against that, the farm saves on bagged nitrogen fertiliser going forward, since synthetic nitrogen use drops or is eliminated on the converted area.

How much you save depends on how much of your platform you convert and how much nitrogen that ground receives today. This is exactly the kind of comparison ODOS Tech runs against your own fertiliser costs.

05 · Fit

Where This Works Best

Strong fit

  • Silage ground due for reseeding, suited to red clover
  • Grazing platforms due for reseeding, suited to white clover
  • Farms able to fit clover into a normal reseeding cycle

Less suited

  • Ground not yet due for reseeding
  • Farms needing the full nitrogen benefit straight away, since clover takes a season to establish
  • Grazing ground already applying little synthetic nitrogen, leaving less to reduce

06 · Model

How We Model This

The share of the farm allocated to silage (for red clover) or grazing (for white clover) is set per farm. The model calculates current nitrogen use on that area and reduces it to the strategy's target, applying the corresponding fertiliser and emissions reduction.

Land share set per farmSilage ground for red clover and grazing ground for white clover are each set from the farm's own layout.
Current nitrogen use calculatedNitrogen applied to that area is worked out from the farm's existing fertiliser data.
Fertiliser and emissions recalculatedNitrogen is reduced to the strategy's target, and fertiliser use and emissions are recalculated.

FAQ

Frequently Asked Questions

What's the difference between red and white clover for this strategy? +

Red clover is used on silage ground and can eliminate synthetic nitrogen there entirely. White clover suits grazing ground and caps nitrogen use at a lower level rather than removing it completely.

Does this affect silage or grass yield? +

No negative impact is expected. Yields are typically maintained or improved through clover's natural nitrogen contribution.

How long before the nitrogen benefit shows? +

A full season is typically needed for the clover to establish and for the nitrogen benefit to show fully.

Is this the same as a multispecies sward? +

No, though they're related. Multispecies swards mix grasses, legumes, and herbs together. This strategy uses clover specifically, targeted at either silage or grazing ground.

Can red and white clover be used on the same farm? +

Yes. Red clover on silage ground and white clover on grazing ground can be modelled as separate parts of the same farm's fertiliser programme.
