  Water treatment for horticulture

  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.

  Hydroponics

  `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

  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.

  Calibration:
  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

  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
