SOIL, WATER AND PLANT SAP ANALYTICS


REMOTE PLANT SENSING

The new FarmView services integrate Sentinel-2 Earth observations. This helps to determine homogeneous and inhomogeneous zones inside the fields. From this data, we can retrieve a useful soil sampling pattern.


SAMPLING AND MEASUREMENT

The iMETOS MobiLab Sampler records the position of the sample and the sampling time. It assigns a unique identifier (UI) to each soil and plant sap sample. After saving the UI, sampling time and position are stored in FieldClimate and an optimized workflow is suggested. Data can be synced with the LOAC Software (Windows 7 or newer). The MobiLab LabOnAChip® measures soil samples via capillary electrophoresis (CE) on small microfluidic chip in an automated manner. An internal standard (ISTD) needs to be added to the sample before measuring.


PLANT SAP AND WATER

The iMETOS MobiLab Lab-on-a-Chip SAP contains everything needed for measuring plant sap. With a simple garlic press and some plastic gear one can easily take samples from leaves. The iMETOS MobiLab Lab-on-a-Chip WATER can be used to monitor irrigation water.

SOIL

The MobiLab Soil Extraction set contains the hardware to take a soil sample and prepare an extract for further measurement. The set contains a sieve and a bowl to homogenize the solid soil sample. A tube inside a tailor-made balance takes the sieved sample up. Distilled water is then added. The balance records the actual share of the sample and the water; thus error tolerant working becomes possible. Afterwards, the tube is placed on a shaker and left there for 30 minutes to extract the nitrogen compounds. Balance and shaker communicate with the MobiLab software via a USB-hub.

The iMETOS Mobilab Lab-on-a-Chip SOIL supplies the Lab-on-a-Chip and the necessary plastic ware to undertake the subsequent soil measurements.

iMETOS MobiLab Lab-on-a-Chip®

(soil, water or plant sap)

Sample volume 50 -100 μl
Measurement range 3-1000 ppm; 0.01-0.5 g/kg
Resolution 0.5 ppm; 1 mg/kg
Accuracy For measurements of liquid concentrations (ppm): ±3 %
For measurements of soil concentrations (mg/kg): ±15 %
Chip lifetime Approximately 300-500 tests
Battery life 2 hours of measuring time

CONSUMABLES

Chemical solutions, plastic ware, filters and microfluidic chips will need to be replaced after every 300 measurements. iMETOS MobiLab SOIL Consumables, iMETOS MobiLab WATER Consumables and iMETOS MobiLab SAP Consumables deliver everything needed for the next 300 measurements. If one wants to change from soil measurement to plant sap and vice versa it will be enough to equip your system with the necessary tools and consumables.

iMETOS MobiLab SOIL EXTRACTION®

Power supply 12 V adaptor for wall outlet
Battery 2 hours of working time

SINGLE NUTRIENT MEASUREMENT

The iMETOS NO3 Electrode is an ion selective electrode (ISE) capable of measuring nitrate. After a two point calibration the Electrode is immersed in the soil extract and returns the concentration of nitrate immediately. This value can be entered into the iMETOS MobiLab Software.
