Abstract:

A system for collecting and chemically analyzing water samples extracted from the soil to measure one or more analytes of interest such as soil nutrient levels of agricultural interest for increasing crop yield and quality in one use of the system. The system includes a sample collection probe () comprising a filter media () arranged to contact the soil when embedded therein and capture a water sample from the soil, and operably coupled to a sample processing sub-system () thereby collectively forming a sampling station (). The sub-system () is configured to receive and analyze the water sample. A programmable probe controller () directs operation of the sample collection, processing, and chemical analysis in situ. A networked array () of sampling probes dispersed throughout the field may communicate wirelessly with at least one remote electronic device such as via the cloud computing (). A modular version of a sampling probe () permits customized sampling at various soil depths.
