The short version

  • Only OneSoil has a free tier, so it costs nothing to try first.
  • Each has a real cost: fieldmargin per-farm pricing inverts badly at the small end: a 30 hectare holding pays the same as a 3,000 hectare estate, so the effective cost per hectare on a smallholding is many times what a large farm pays.; OneSoil no price, tier or minimum is published; enterprise access requires scheduling a demo and the only self-serve entry point is a free demo app
  • They diverge on capability: fieldmargin covers Field mapping, OneSoil covers Satellite field monitoring.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

fieldmargin

  • Per-farm pricing inverts badly at the small end: a 30 hectare holding pays the same as a 3,000 hectare estate, so the effective cost per hectare on a smallholding is many times what a large farm pays.
  • It is not an agronomy platform, so there is no variable rate prescription engine and no nutrient planning to a standard a UK agronomist will certify, meaning most arable users still pay for Gatekeeper or an agronomist's own system alongside it.
  • There is no direct submission route into Basic Payment Scheme, Sustainable Farming Incentive or equivalent schemes, so the compliance paperwork that costs farms real money still has to be assembled elsewhere.
  • Machine integration is limited compared with Climate FieldView or Operations Center; as-applied data from the sprayer or drill generally is not flowing in automatically, so application records depend on someone typing them.
  • Satellite NDVI is confined to the top tier and is standard public imagery, so cloud cover in a British winter means long gaps and the imagery is not a substitute for the aircraft or drone capture that specialist providers sell.

OneSoil

  • No price, tier or minimum is published; enterprise access requires scheduling a demo and the only self-serve entry point is a free demo app
  • Field monitoring is satellite based, so the platform provides no in-field sensor or soil measurement of its own

Answered from the vendors’ own pages

fieldmargin: Does it charge per hectare?

No. Subscriptions are per farm with unlimited hectares and unlimited team members, which is why it is cheap on large acreages and proportionally expensive on small ones.

OneSoil: How much does OneSoil cost?

OneSoil does not publish pricing on its website. The platform offers a free trial at app.onesoil.ai or a demo can be scheduled through their contact form.

Source
fieldmargin: Can I submit my BPS or SFI claim from it?

No. It holds the records that support a claim but there is no direct submission integration, so the claim itself is prepared elsewhere.

OneSoil: What pricing model does OneSoil use?

OneSoil's pricing model is not disclosed on their public website. Contact [email protected] or schedule a demo to learn about pricing and subscription options.

Source
fieldmargin: Does it work without mobile signal?

Yes. The mobile apps capture records offline and sync when the phone regains a connection, which is the main reason it gets used in the far corners of a farm.

fieldmargin: Is there a free plan?

There is a 14 day trial rather than a permanently free tier. After that every farm is on a paid plan.
