    Sampling and drilling equipments for the agriculture industry

    Farmers and researchers in the agricultural industry have used AMS sampling equipment for over 50 years. The AMS Step Probe, Soil Recovery Probes, and a variety of one and two-piece augers are used in the agricultural sampling market to obtaining disturbed samples at or near the surface and for boring to depths where more precise samples can be obtained. AMS now offers a variety of nematode sampling equipment, ATV-mounted PowerProbe rigs, and one and two-piece open-faced augers.

  • Measuring Ion Concentrations in Hydroponics Samples

    Required Apparatus:

    • Aptisens Digital or Mobile Multiple Ion Kit

    Required chemicals:

    • Aptisens multiple ion conditioning solution
    • Aptisens multiple ion HORTICULTURE calibration solutions
    • Deionised water

    Sample Preparation:
    Typically, it is not a requirement to filter a hydroponics sample.

    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 aqueous extract and ‘Take a Sample’ reading. The concentrations for each ion will be displayed in ppm or mmol / L.

    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.

  • 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.

  • 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

    Improved Reproducibility and Reduced Sample Preparation Time for the HPLC Analysis of Aflatoxins in Raw Peanut Paste

    The US FDA and international regulatory agencies have set contamination levels for aflatoxins in animal feedstuffs. Since Aspergillus may infect commodities pre-harvest, during storage or during processing, monitoring for aflatoxins in associated agricultural commodities at all stages of production is requisite. Field screening methods exist that are adequate to estimate contamination levels for aflatoxins. When additional confirmation or quantification is desired, chromatographic laboratory analysis is often necessary. Preparation of matrix samples prior to chromatographic analysis typically requires extraction and purification. Commonly, immunoaffinity columns (IAC), which employ a multi-step bind and elute mechanism to concentrate and purify aflatoxins, are used to purify matrix samples for subsequent analysis. Solid phase extraction (SPE), an alternate method which may use interference removal, can also be employed.
