Fertilization Meter for pot plants

The Fertometer measures the level of nutrients in the soil of your potted plants and uses a light to indicate feeding requirements. Insert the Fertometer’s probe into the soil and press the button. A yellow light indicates that your plant requires feeding. A green light indicates that your plant has sufficient nutrients in the soil. Do not add fertiliser if the red light shows. In short: the Fertometer makes it possible for you to provide the ideal conditions for your plant.

How does the fertometer work?

The Fertometer uses the process of electrolysis and is also referred to as an EC-meter(Electrical Conductivity) in technical terms. 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. It is, though, not possible to recognise from the measurement if a plant is lacking other elements such as potassium or magnesium. An EC-meter reads and interprets an electrical current. This interpretation could be visually represented by an analogue or a digital display. In the case of the Fertometer, a clear and simple indication of the result has been chosen using three lights.
