The short version

  • 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.; Teralytic the company is reported at around six employees, so if it stops trading the buried probes become inert hardware, which is the single biggest risk in a multi-year soil sensing deployment.
  • They diverge on capability: fieldmargin covers Field mapping, Teralytic covers Wireless NPK sensing.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

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.

Teralytic

  • The company is reported at around six employees, so if it stops trading the buried probes become inert hardware, which is the single biggest risk in a multi-year soil sensing deployment.
  • No current pricing is published and reported figures have moved between roughly 300 and 500 US dollars per probe per year, so a buyer cannot model the cost of a hundred-probe deployment without a quote.
  • The subscription is mandatory for the probe to report at all, so the up-front hardware payment buys nothing durable and a lapsed account means a field full of dead instruments.
  • In-field NPK sensing is scientifically contested and readings need interpretation against soil type and calibration, so agronomists will not treat the numbers as interchangeable with a lab test and many will insist on both.
  • Spatial coverage is the unsolved problem: a probe measures one point, soil varies over metres, and covering a field properly multiplies both the hardware and the annual subscription by the number of zones you care about.

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.

Teralytic: Can I buy the probe without a subscription?

No. The probe reports through Teralytic’s network into its cloud, and without an active subscription it does not deliver data.

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.

Teralytic: Does it replace lab soil tests?

No. It gives continuous in-season trend data. Most agronomists will still want lab results for absolute nutrient values and for compliance records.

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.

Teralytic: How much does it cost?

Teralytic does not publish current pricing. Reported figures have ranged from roughly 300 to 500 US dollars per probe per year including hardware and connectivity.

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.

Teralytic: How many probes does a field need?

That depends on soil variability. One probe represents one point, so a field with several distinct soil zones needs one per zone to be meaningful.
