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

Problem: Drinking water plants that use chlorine for disinfection must ensure organic matter is removed before chlorination to limit the formation of harmful disinfection by-products (DBPs), most commonly Trihalomethanes (THMs) and Haloacetic acids (HAA5).

The MAGNATION Next Generation water systems make water more productive by increasing its bioavailability to plant cells. It delivers more oxygen and nutrients to the plant while reducing scaling, harmful salts, and total dissolved solids (TDS). The increase in nutrient solubility creates healthier plants and greater yields. The MAGNATION Next Generation water systems produce more plant for less water—a powerful boost for more profitable farming through the power of natural, magnetic science. MAGNATION Next Generation water systems pay for themselves within one harvest year, usually with a profit, quickly returning your cost of investment. Then, year after year, they deliver increased returns by improving production and yield.
Horticultural and greenhouse operations are facing increasing challenges in dealing with sanitation issues related to water treatment. Over the course of growing a crop, pathogenic microorganisms accumulate and algae flourish on moist surfaces posing a constant threat to plants and produce. The main challenges lie the areas of irrigation water, elimination of biofilm and algae control. Existing biocidal products, while effective in killing algae, are not effective in removing biofilm from the water lines. The ultimate solution would be to employ a biocide that is capable to control algae on greenhouse surfaces and strip the biofilm in irrigation lines. Chlorine dioxide has demonstrated to possess both properties.

MAGNATION water and energy-saving systems makes dollars and sense. It reduces water needs by 10 to 30%, a cost saving that feeds directly into the city’s budget. It adds further savings by reducing scaling, a major source of costly maintenance. Providing water to parks, ball fields, shrubbery, grass, flowers, and trees represents only a fraction of the load put on a city’s water budget. Add to that the recurring cost of pipe replacement from scaling. These dollars that could have been supporting city services and programs are lost to watering and maintenance demands. MAGNATION water and energy-saving systems pays itself back virtually overnight, reversing the flow of money back into the city budget through substantial savings. It employs magnetic science to create healthier, hydrating water that carries benefits for plants and humans alike. It fits the spirit of this planet’s future: doing more with less. When magnetized by the The Magnation Industrial NEXT GENERATION and BIG BLUE Pump & Irrigation systems take less water to get the job done better, providing solid fiduciary results.
`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.

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.

Soil moisture content is the amount of water within a certain volume or mass of soil. Together with soil temperature is a fundamental indicator of the eco-hydrological state of a field. A precise measurement of how water and temperature are spatially distributed in soil, and their evolution in time, is crucial to the forecast and/or quantification of many key processes like plants growth, infiltration, runoff, plant and evaporation.

Greater crop quality and yield
Forms a physical barrier between the plant and the environment, protecting it from plagues, insects, infections and dust.
Allows the seepage of the water, air and light needed for the growth of the plant.
Generates a micro-climate that promotes better yields and quality of the crops.
Minimizes or even eliminates the use of agro-chemicals in the crops. Ideal for organic or bio-rational producers.
Adds value to the crops in export markets.
Main crops: Melon, Pumpkin, Watermelon, Pepper, Tomato, Cucumber, Hot Peppers, Flowers, among others.

Surface preparation: Your pond surface needs to be clean, dry and structurally sound. We suggest not using any detergents in your Pond. A medium bristle brush and water is all that is needed. You want the surface to be clean of any dirt that will be picked up with the nap of the roller or in the paintbrush used during the application process. Avoid cleaners and detergents since any remaining residue may harm your fish or plants. Only if your pond does not have plants or fish should you consider using cleaning solutions. On an epdm liner that has not been coated with other coatings it is simply a one coat application of PondPro2000.
