`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.

The controlled composting of organic waste with the Toptex protection fabric leaves odour emissions at bay and increases the quality output significantly. Composting is the conversion of organic wastes into high quality humus. Through systematic controls these materials can be returned to the earth, completing the cycles of nature and improving the soil to which it is applied.

Alfalfa is a crop of the legume family and its scientific name is Medicago sativa. Alfalfa is a perennial plant of erect growth and is one of the most extended forage crops within temperate climate countries.
The olive tree is one of the most traditional and old crop of the Mediterranean areas. The olive oil obtained has served for centuries as food and applications such as raw material to lighting and medical products. The actual situation is exceptional due to it high demand and profitability, thanks to the successful food campaign which stands out its therapeutic and nutritive properties. The crop surface is continuously growing. Spain and Italy are the main producers worldwide, followed by Greece, Turkey and Tunisia.
Subsurface drip Irrigation Systems (SDI) are a suitable agronomic option for all type of crops: woody crops (almond tree, vineyard, olive tree, pistachio tree, peach tree, etc.) and extensive crops (corn, vetch, barley, alfalfa, etc.). The SDI is an irrigation technique that allows the supply of water and nutrients in a localized way under the surface. This fact conditions and optimizes the growing of roots and the development of the plant. This practice makes possible a more efficient use of the water, energy and fertilizers, becoming the alternative with best results from an economic, agronomic and ecologic point of view.
Tomato is one of the most spreaded agricultural products all around the world and even of higher economic value. Its demand is continuously increasing and with it, the crop, production and trade. The world production is of 85 millions of tons (FAO 2007) and the countries with higher productions are China, Mexico, United States, Turkey, Spain, Italy and Egypt. Continentally, according to FAO data, Asia participates with no more than 50%, followed by America with a 20%, Europe 15% and the rest comes from Oceania and Africa.
At fish breeding humic acids are known for long as an integral part of natural waters for the bio-logical improvement of the water quality. For this purpose peat based products were often used to optimize the pH with the containing humic acids. Huminc acids based products on base of lignite like HuminFeed® in the field of aquacultures are an object for research for many years yet. Within the research acitivities regarding the use of HuminFeed in aquacultures and ornamental fish breeding the following positive effects amongst others could be observed by the Leibniz-Institute of Freshwater Ecology and Inland Fisheries in Berlin:

Humic acidscan be successfully used as an additive in animal feed. Various research trials conducted worldwide have all showed positive results concerning the use of humic acids as an organic feed ingredient. Increases in liveweight of animals, improved growth rates, increased feed intakes and food conversion ratios and a stronger resistance against diseases are the common results of these trials. By improving immune function of animals, especially of young animals, humic acids also reduce the incidence of enteric disease and diarrhoea.

TeraFlo® significantly reduces watering requirements per cycle of irrigation while maintaining adequate moisture for good plant health and growth. Due to its filtration properties, excessive moisture also flows through the soil thereby preventing environments for fungal growth. It draws moisture from the air and the surface and attaches itself to the plant roots from sources not previously available. It provides proper wetting and drainage in non-soil media as well as eliminating unusable water. TeraFlo® dramatically improves the ability of rainfall and water to easily penetrate the soil surface and gain access to the root zone. By encapsulating the soil particles, it significantly decreases friction allowing for easy and rapid water penetration and filtration into any soil condition; hardpan, compacted or otherwise. It improves the efficiency of all applied additives (pesticides, insecticides nutrients, etc) preventing rapid leaching of these products. This increases their effectiveness and reduces over all application quantities making additive usage far more cost effective. Holding organophosphates in the soil reduces the leaching of these toxins which significantly improves their performance. The product has a special affinity to nitrogen thereby reducing nitrate leaching protecting against groundwater contamination. TeraFlo® prevents the buildup of soluble sodium salts contained in fertilizers and water sources thereby reducing stress conditions. Continual use will keep the root zone free of sodium salts. TeraFlo® increases microbial activity which aids in root cell buildup resulting in faster uptake of nutrients. TeraFlo® reduces soil erosion from in-furrow irrigation and significantly reduces nitrogen loss in head ditch irrigation systems. TeraFlo® improves drip applied fumigant systems allowing for a more efficient and longer release system. Teraflo provides lubrication to pump parts, valves, and other parts of pressurized water systems preventing products in the irrigation piping from sticking to the walls, thus reducing drip and irrigation head clogging. This reduces downtime, repair costs, and maintenance.
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.

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
