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:

Precision agriculture is no longer a new term in crop production. It is now a widely accepted practice. Aerial imagery is a key component in utilizing precision agriculture techniques for the management of farmland. The GeoVantage Imaging System provides high-resolution, orthorectified images that are used by Cooperatives, Ag Service Providers (ASPs), Crop Consultants, and Growers to:
- Create management zones
- Evaluate the effectiveness of fertilizer applications
- View the whole farm/field
- Perform in-season analysis to make crop management decisions
- Manage geo-referenced soil sampling
- Precisely schedule irrigation
- Scheduling of pesticide applications
- Find mechanical errors in application equipment

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

Nitrogen supply for agricultural applications and in particular:
- Nitrogen injection in cultivated soils;
Special Know-How & Services from NOXERIOR
We at NOXERIOR have developed a special and patent pending nitrogen supply system for micro-organism pest control in cultivated soils. This patent pending nitrogen soil injection and distribution system in combination with our NITROSWING® PSA nitrogen generator offer you a unique and environmental friendly alternative to combat fungi and parasites, like nematodes, to protect your crop. A reliable estimation of nitrogen requirements and a correct dimensioning of the nitrogen generation system from our NITROSWING® PSA nitrogen generator product range will be determining for the economical and environmental benefits you expect from our patent-pending on-site nitrogen generation and distribution system.
We will provide consultancy regarding the most efficient nitrogen distribution as well as patent-pending technology for nitrogen injection into the soil under consideration of all relevant parameters. Together with you will find a compromise between the use of energy and the efficiency of nitrogen transfer to optimise costs.
