Alongside warmth, light, air and water, plants also need nutrients in order to grow. They are often available to the plant in the soil in an unusable form or in small amounts. The use of fertiliser makes it possible to supply the plant with additional nutrients. In doing so, the amount should be adapted to the soil and the plants’ requirements.
In agricultural areas, due to intensive use of nitrogen fertilisers, the soil often becomes acidic and the groundwater contains too much nitrate. This groundwater can only be used with restrictions. Also, soil organisms are negatively affected. As a consequence, soil fertility decreases. To keep your garden healthy, it is important to reduce fertilisation to a minimum in your own garden, too. The exhibits present two different fertilisation methods.
