Measuring Ion Concentrations in Plant Tissue
- Aptisens Digital or Mobile Multiple Ion Kit
- Weighing scales
- Liquid measurement device e.g. graduated cylinder
- Bowl for stirring
- Spoon for stirring

- Conical flask / vessel
- Aptisens multiple ion conditioning solution
- Aptisens Plant Tissue multiple ion calibration solutions
- Deionised water
This preparation can be applied to any plant tissue. Take a sample of lettuce and remove any soil but do not wash the plant tissue as doing so may reduce the number of ions in sample. Weigh this sample and record (say 100 g). Macerate the plant tissue in a blender and add a known amount of hot deionised water to the sample to extract the nutrients. For example, dilute the sample two-fold (200 mL), three-fold (300 mL) or five-fold (500 mL). Ensure all the plant tissue is covered with water and leave to sit for approximately 30 min with some stirring. The sample then needs to be filtered.
Set up a funnel with folded filter paper in a conical flask or any vessel that can hold a funnel. Pour the plant tissue and water into the funnel and allow the mixture to filter. Collect the filtrate.
Before use the multiple ion probe must be conditioned in Aptisens multiple ion conditioning solution. Ensure the correct calibration solutions for a three-point calibration are set up on the Mobile meter or MeterLink. Follow the instructions for calibration and proceed to take a sample reading when the calibration data is ‘very good’ or ‘good’ for all ions.
Place the probe in the plant tissue filtrate and ‘Take a Sample’ reading. The concentrations for each ion will be displayed in ppm or mmol / L.
Remember to multiply these concentrations by the dilution factor.
After taking your reading be sure to remove the sensors from the solution as quickly as possible, rinse with deionised water and replace the cap of the probe

Agriculture provides essential societal benefits: supply of food and commodities, economic development and employment. In turn, rural communities are under increasing pressure arising from increased productivity requirements, soil erosion and sealing, water scarcity, natural hazards and climate change.

Measuring Oil and Water in Seeds using the MQC Benchtop NMR Analyser. The breeding, cultivation and processing of seeds to obtain vegetable oil is a major global industry. The amount of oil in seeds and water in seeds are critical parameters which need to be understood at all stages of the industry from plant breeding through commercial agriculture to milling and processing. Oils derived in this manner are used in foodstuffs, the manufacture of biofuels and as a chemical feedstock for many products.

Soil moisture content is the amount of water within a certain volume or mass of soil. Together with soil temperature is a fundamental indicator of the eco-hydrological state of a field. A precise measurement of how water and temperature are spatially distributed in soil, and their evolution in time, is crucial to the forecast and/or quantification of many key processes like plants growth, infiltration, runoff, plant and evaporation.
