Long-Term In-Situ Soil Monitoring as a Bridge Between Agricultural Productivity and Biodiversity Conservation

Healthy soil underpins terrestrial biodiversity by supporting microbial food webs, regulating nutrient and water cycling, and enabling diverse plant communities that form the foundation of higher trophic levels. Both farmers and conservation organisations monitor soil properties but historically for different objectives. In agriculture, measuring soil moisture, temperature, electrical conductivity (EC), pH, and soil respiration (CO2) is used to optimise production outcomes, particularly irrigation scheduling and fertiliser efficiency, enabling producers to maximise yield while reducing water, nutrient inputs, and costs.

In contrast, conservation organisations monitor the same variables to assess restoration effectiveness and ecosystem recovery. Soil data evaluate interventions including landscape rehydration works, revegetation programs, and grazing management, and provide early warning indicators of ecosystem stress, such as declining soil moisture or increasing salinity prior to visible vegetation loss during drought.

Despite their value for decision-making, long-term in-situ soil monitoring has been constrained by high equipment and deployment costs. Expenses arise from ruggedised, low-power sensors and hardware, data transmission fees, installation and maintenance in remote environments, and logistical challenges in terrain lacking power and reliable communications. Consequently, most monitoring relies on short-term sampling incapable of capturing long-term trends, seasonal variability, or ecological tipping points at landscape scale.

Baseliner Soil is a real-time, in-situ system developed with ecologists and scientists for conservation and restoration. Using affordable, lab-verified sensors, it measures soil moisture at multiple depths, soil temperature, EC, pH, and CO2, transmitting data to the internet to generate long-term time-series datasets able to detect soil condition changes overlooked by short-duration monitoring.

The system is power-optimised for long-term deployment, ruggedised for harsh field conditions, offers multiple communications options for remote sites, and is cost-optimised for scalable monitoring networks.

By adopting conservation monitoring practices, farmers enhancing on-farm biodiversity can assess regenerative actions such as cover cropping, reduced tillage, rotational grazing, riparian restoration, tree belts, and organic amendments. Improvements in soil carbon, respiration (CO2), aggregate stability, moisture retention, and reduced salinity can provide early evidence of recovering soil food webs, increasing plant diversity, and expanding habitat quality, bridging agriculture and conservation toward sustainable, biodiversity-positive farming systems.
