Soil moisture sensors and field telemetry for commercial farms
Soil moisture, tension and salinity sensors and the wireless networks that report them.
Requests go through SeedMatch Group. Our team reviews each request and coordinates supplier contact; buyers and suppliers are not put in direct contact. The buyer service is free, and projects are qualified from USD 250,000.
How should a buyer specify precision soil sensors and telemetry?
Soil sensors measure water content, soil water tension or salinity at a point, and telemetry carries the readings to an irrigation controller or data platform. Readings are only useful when the sensor type suits the soil and crop and is installed and calibrated for that soil.

| Type | Maturity | Best for | Key limitation |
|---|---|---|---|
| Capacitance (FDR) soil moisture probes | Mature | Irrigation scheduling in orchards, vegetables and substrates. | Point measurement, not whole-field |
| Time-domain reflectometry (TDR) soil moisture systems | Mature | Irrigation research, high-value orchards, trials. | More complex and costly system |
| Tensiometers | Mature | Irrigation scheduling, greenhouse substrates, research. | Needs refilling and servicing |
| Soil EC and salinity sensors | Established | Salinity and leaching management, fertigated crops. | Bulk EC differs from pore-water and saturation-extract EC |
| Wireless and LoRaWAN field telemetry | Established | Remote soil, weather and water monitoring. | Coverage needs a site survey |

How to specify this category
What to put in your request
- Fields, crops and soil types, with area and number of monitoring sites
- What to measure — water content, soil water tension or salinity (EC) — and at which depths
- Telemetry: distance to the gateway, power source and reporting interval
- The irrigation controller or data platform the readings must reach
- Installation, soil calibration, training and maintenance scope
Questions to ask suppliers
- Which calibration applies to this soil, and how will it be checked against soil samples?
- Which radio band and type approvals apply in the destination country?
- How many gateways are needed to cover the site, and who maintains them?
- Which platform or controller stores the data, and can it be exported?
Strengths and limitations buyers weigh
| Option | Strengths | Limitations |
|---|---|---|
| Water-content probes (capacitance/FDR, TDR) | Log volumetric water content continuously, at several depths if needed. | Point readings that need soil-specific calibration, especially in clay or saline soils. |
| Tensiometers | Read soil water tension directly; mechanical versions need no power or soil calibration. | Need refilling and servicing, and have a limited range in dry soil. |
General trade-offs; a specific variety's traits come only from its supplier documentation.

It depends on soil, crop and how the readings will be used. Capacitance (FDR) probes and TDR systems measure volumetric water content, tensiometers measure soil water tension and EC sensors indicate salinity. Each needs correct installation and calibration for the soil; the product types table compares uses and limitations.
Number of sensors and sites, field size and distance to the gateway, power source, the data platform or irrigation controller to connect to, reporting interval and who will maintain the network.
Suppliers, producers and exporters are responsible for their products meeting product, labelling, certification, phytosanitary and export requirements of the origin and destination countries. A listing does not confirm compliance, availability or suitability.
Availability and the ability to trade depend on the law of each origin, destination and transit country and on the relevant permits and approvals. SeedMatch Group is not a manufacturer, importer, exporter, seller or regulatory approver; requests are reviewed by our team before any commercial introduction. Each participant is responsible for the requirements of its own role under applicable law: suppliers for their products in the origin and destination countries, buyers for their own import permissions and due diligence.
