Alongside heat, 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.
“Near-natural allotment garden” competition
With 7 allotment garden plots per 100 inhabitants, Leipzig is a leader in Germany. Allotment gardens complement the urban green structure and fulfil important social and environmental functions. The idea of the city of Leipzig is to raise ecological awareness in cooperation with allotment garden and environmental organisations. With this goal in mind, the City of Leipzig has been holding the “Near-natural allotment garden” competition every second year since 2014. Learn more here.
