Nutrient Monitoring Applications

  • Nutrient testing for the agriculture industry

    Different sorts of food and agricultural products may contain various concentrations of nutrients, ranging from trace amounts to percentage levels. While most of these nutrient concentrations are healthy, some can be toxic to humans or animals. Bruker offers simple and effective nutrient testing solutions for the determination of nutritional elements in food and agricultural samples with routine and reliable nutrient analysis. All of our solutions enable fast, accurate and precise measurement of nutritional contents and concentrations from sub parts-per-trillion to high percentage ranges.

  • Fertigation Monitoring /Nutrient Concentration Monitoring

    We have optimized six and four ion probes for horticultural applications. For growers, these products offer a “lab-in-hand” solution — a quick and affordable way to maintain the proper nutrient balance required for better yield, improved flavor and color, greater disease resistance and longer shelf life. Controlling the concentration of nutrients in liquids is a vital step in the fertigation process. Today, nutrient levels are tested daily, most commonly by measuring pH and EC, and dispatching samples to offsite labs for analysis. This traditional testing protocol is time-consuming and costly, and delays access to information on potential yield-threatening nutrient levels.

  • Data analysis and visualization tools for agriculture

    Given the large areas and relatively shallow soil depths associated with agriculture, the industry standard has long been two-dimensional analysis. However, over the past decades many of C Tech’s customers have discovered the advantages of analyzing and understanding soil properties on a true 3D volumetric basis. Nutrient concentrations, plant available water and stratigraphy are examples of data which are best addressed on a volumetric basis.

  • Measuring Ion Concentrations in Plant Tissue

    Measuring Ion Concentrations in Plant Tissue

    Required Apparatus:

    • Aptisens Digital or Mobile Multiple Ion Kit
    • Weighing scales
    • Liquid measurement device e.g. graduated cylinder
    • Bowl for stirring
    • Spoon for stirring
    • Funnel
    • Filter paper / muslin
    • Conical flask / vessel

    Required chemicals:

    • Aptisens multiple ion conditioning solution
    • Aptisens Plant Tissue multiple ion calibration solutions
    • Deionised water

    Sample Preparation:
    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.

    Calibration:
    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.

    Sample Reading:
    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.

    Probe Care:
    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
