    `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.

  • 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.

  • 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

  • Irrigation

    "maximizing water utilization" By reducing friction & surface tension, TDS, salts, Sodium Absorption Ratio, balancing pH & Calcium/Magnesium Ratios, bicarbonates thus maximizing bio-availibility of nutrients and oxygen to plants and improving soil penetration and soil moisture retention, "mellower soils" & healthier plants; and reducing operational costs by saving water/energy, scale build-up, pesticides, herbicides, fertilizers and maintenance. Magnation water treatment, like the Magnation Scale Reduction System, creates additional collisions of ions that precipitate CaCO3, and it changes the free gas content in water that leads to improved crop yields. These mechanisms create many applications for the use of MW, with the use of MW having the potential to become more commonly used in the irrigation of crops, as drinking water for livestock and to prevent and remove scale buildup in hydrologic infrastructure. With many studies showing increases in crop yields & animal/soil health.

  • 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
