Rapitech - Fertométre

The Fertometer works on the same principles as a plant. Like the roots of a plant, it absorbs nutrients from the soil. By measuring the quantity of the absorbed substances, it can be determined whether there are sufficient nutrients left in the soil. These absorbable nutrients are called ions and consist mainly of nitrogen, the principal nutrient for plants during the growing season. All ions are involved in the measurement, so as to get a good indication of the amount of fertiliser in the pot.
