  • 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

  • Greenhouse Irrigation Management

    Why efficient irrigation is important. Water and fertilizers are essential to the growth of your crop. However, these resources are becoming increasingly scarce worldwide. Modern horticulture has various possibilities for saving water and fertilizers. For example, recirculation of drain water reduces consumption by at least 30%. Exact alignment of the plant’s needs and the irrigation also provides an important contribution to savings. An associated advantage is that an optimal irrigation strategy will increase your crop performance and your profit. Water solutions for your horticultural company With sustainable automation solutions from Hoogendoorn, you can regulate the irrigation in your greenhouse and in your open field in a targeted manner. The innovative iSii process computer precisely coordinates the dosage of various water sources such as rainwater, well water and drain water with the demands of the crop. Wherever possible, iSii also regulates the complete recirculation and disinfection of drain water. The advanced software anticipates changing conditions pro-actively. For example, the frequency and duration of irrigation sessions are adjusted prior to times of more or less sunshine. Based on the measured water intake of the plants and the water content of the soil or substrate, the irrigation can be tailored even more precisely to the growth process

  • 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
