About fertilizing potted plants and plants in vegetable gardens

During growth season both potted plants and plants in your vegetable garden need enough nutrients to grow, to flower and to crop well. There is a limited amount of nutrients in the soil, therefore it’s important to measure the level of nutrients and to fertilise in time if necessary.

Measure the level of nutrients in the soil of potted plants and/or vegetable gardens

The fertometer measures the level of nutrients in the soil of your potted plants and your vegetable garden and uses a light to indicate feeding requirements.

EC (Electrical Conductivity): the fertometer is an EC-meter and provides fertilizing advice

The fertometer uses the process of electrolysis and is also referred to as an EC-meter (Electrical Conductivity) in technical terms. It 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 in the soil, it can be determined whether there are sufficient nutrients left. The colour of the light will show you directly the feeding condition of the soil and will enable you to act directly if necessary.

 

How to measure the level of fertilisation in the soil with the fertometer

Use of the fertometer in potted plants like house plants or container plants

Insert the fertometer’s probe into the soil and press the button. A yellow light indicates that your plant requires feeding immediately. A green light indicates that your plant has sufficient nutrients in the soil. Do not add fertiliser if the red light shows. for you to provide the ideal conditions for your plant. Please read also the general instructions below.

Use of the fertometer in the vegetable garden to check if you need fertilising

Take a pot and fill it up with the soil of your vegetable garden. Press the soil in the pot to make it more dense and water the soil well until it’s uniformly wet. Now you have to wait for about 30 minutes before you can start measuring. Now drive the pin of the fertometer all the way into the soil and push the button. If the soil of your garden has a dense structure (e.g. it contains clay) you can use the fertometer directly in the soil of your garden under the condition the soil is wet. If the yellow light shows the activity in the soil is low. In this case we recommend to fertilise. Don’t add too much fertiliser, this might lead to over-fertilisation. When the green light aluminates your soil contains enough fertiliser . In this case no action is needed. If the red light shows the soil contains too much fertiliser and you will need a soil analysis.

General instructions for using the fertometer

To get a reliable test result it is important that the soil is uniformly wet. If this is not the case, then water your plants first and wait at least 30 minutes before you start measuring. We recommend to water your plants in the morning and to measure in the afternoon. If the soil is (too) dry, the measuring results might be unreliable.

In order to get a reliable test result the soil need to be a bit « loose », ideally the soil of your vegetable garden has about the same structure as potting soil. If the structure of your soil contains a lot of clay or a lot of sand , the test results of the fertometer won’t be accurate enough. It makes only sense to do measurements during the growing season starting end of April/beginning of May.

Recommendations for using the fertometer

The fertometer is not recommended for orchids and plants which thrive on poor soil such as heather, nor for seedlings and cuttings.

Take care that the pin is clean before measuring.

The best results are obtained at temperatures between 18 and 23º C.

It is important to clean the pin after use and to store your fertometer in a dry place to prevent it from oxidation. If the metal of the pin starts to get dull you can clean it carefully with a slightly wet sponge or a soft scouring pad and dry it with a soft cloth.

Never leave the fertometer standing in the soil.

We recommend to measure at different spots in your vegetable garden or if your plants grow in a big container, this will increase the reliability and will enable you to compare the results.

The fertometer uses a flat 9V battery type 6LR61 (not supplied). To test the battery push the button. The yellow light will show. If the light does not come on or flickers the battery is flat.

The fertometer is not suitable for liquids and only water resistant (not waterproof).

FAQ – how to fertilise plants? What does the fertometer measure?

No light shows when I press the button

Change the battery

The yellow light flickers or switches off when I press the button

Change the battery

Several measurements in different spots in a big container or the vegetable garden lead to different results

The soil has to be moist everywhere and you need to measure in plain soil, so avoid obstacles like roots. Try to do a lot of measurements and follow the colour of the light which shows the most.

Which EC values are being used by the fertometer?

The EC values of the fertometer are: yelow/green = 0,35 mS/cm ; green/red = 1,00 mS/cm. These values are comparable with 0,2 g/l and 0,65 g/l salinity at 20°C.

How do I add fertiliser?

We recommend organic fertiliser if available. You can buy any type of fertiliser in special garden stores or supermarkets. Follow the instructions for use on the cover, but never exceed the recommended dose. Keep checking your plants regularly with the fertometer.
