nutrient solution Applications

  • 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.

  • Microbial Solutions for Plant Health and Growth

    Microbial Discovery Group excels in identifying antibacterial, antifungal and growth promotion properties to improve plant health and growth.

    Feeding the ever growing population will become increasingly difficult as resources continue to become constrained or diminished.  Microbial technologies will help to fill the gap through a variety of differing mechanisms including nutrient creation or release, pathogen and pest resistance, plant growth promotion and protection of the plant against environmental stresses.  MDG has library screening technologies to help you find the virtual needle in the haystack when seeking biological solutions.  We have the capabilities, capacity and commitment to provide the biological wonders that will help feed the world.

    `A technique of growing plants in nutrient solution”. Hydroponics literally means water-working or water-activation. It is a cultivation technique for growing plants in highly oxygenated, nutrient enriched water, rather than soil. The nutrient solution and its management are the cornerstone for a successful hydroponics system. The function of a hydroponics nutrient solution is to supply the plant roots with water, oxygen and essential mineral elements in soluble form. In soil, biological decomposition breaks down organic matter into basic nutrients that plants feed on. Water dissolves these nutrients which allows uptake by the roots. For a plant to receive a well balanced diet, everything in the soil must be in perfect balance.

    Odor control for the poultry feed production

    The animal feed industry has its roots in the way traditional millers grinded the grains centuries ago, using (wooden) windmills. Nowadays feed is produced for chickens and other poultry, as well as for cattle, pigs and horses. There is a wide variety of feed and grains produced, with different raw materials (nutrients) applied in several compositions.

    In this modern era electric driven pellet mills are applied and grains are cooled mainly in counterflow coolers. To remove dust from the used cooling air usually a baghouse filter is being used which can meet the current severe dust emission standards. After this the air eventually will be blown outside. Especially the cooling air of poultry feed and pig feed production should be deodorized to prevent complaints.

    A factory usually has multiple pellet lines in service with about 15,000 to 25,000 m3/h of cooling air per line. Aerox has developed specific solutions for this industry.

    On the one hand a compact Aerox®-Injector can be installed per pellet line. On the other hand, airflows of different production lines can be joined together and can be treated with one compact Aerox®-Injector. In practice, this can be added up to 4 lines with a total airflow of up to 90,000 m3/h.

    Since the Aerox®-Injector can run on different capacities unnecessary power consumption is prevented when not all pellet lines are in service. This benefits the environment and reduces operational costs.

  • Super Absorbent Water Management Agrotextiles

    Our Agrotas range of Super Absorbent Fibre (SAF) and converted products allow you to achieve optimum nurturing and growth conditions whilst effectively reducing overall water usage. Our unique fibrous technology creates new possibilities for the development of nonwoven fabrics that can be used as both temporary and long-term solutions, from hanging basket liners to commercial scale projects, even in areas of low water availability. Such fabrics are designed to achieve highly controlled delivery of water and nutrients to root systems, whilst significantly reducing evaporative loss and water seepage. SAF can also be dosed directly to the soil. Advantages: •Ease of handling and installation •Wide range of formats •Suitable for short-and long-term use •Reduced re-watering periods •Enhanced establishment times •Accurate, consistent nutrient distribution

  • 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.

    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
