Nicolon Ground Cover Fabrics control weeds found in land maintained by professional growers and landscapers. These highly useful fabrics feature woven polypropylene that allows water and nutrients to pass through while preventing roots from implanting into the soil. Available in widths from 3 to 15 feet (0.90 x 4.5m), Nicolon ground cover fabrics can also be utilized in soil separation and barrier fencing applications.

`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.

Measuring Ion Concentrations in Plant Tissue
- Aptisens Digital or Mobile Multiple Ion Kit
- Weighing scales
- Liquid measurement device e.g. graduated cylinder
- Bowl for stirring
- Spoon for stirring
- Filter paper / muslin
- Conical flask / vessel
- Aptisens multiple ion conditioning solution
- Aptisens Plant Tissue multiple ion calibration solutions
- Deionised water
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.
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.
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

The agriculture industry is a water intensive industry that needs a constant contaminant free water supply to ensure high harvest yields and healthy farm livestock. This requires agriculture water treatment solutions and specific soil additives that are sustainable and environmentally friendly. Agriculture water treatment and waste water treatment is essential to prevent bacteria, fungus, while reducing pesticide and nutrient pollution degradation of farmland used in commercial agriculture and horticulture operations. Genesis Water Technologies can engineer, build and provide sustainable agriculture water treatment and wastewater reuse systems as well as specific soil mediums for both greenhouse nurseries and commercial farming operations.
