We test substrate components that appear to be suitable peat substitutes for the horticulture industry. In order to implement these new products, production systems have to be adapted to the new components of the growing media.
Soil blocks for seedlings: In order to form soil blocks, a sufficient amount of peat is necessary. By how much can this be reduced without compromising the quality of the blocks or the seedlings?
Organic cultivation: Organic fertilisers are used in organic farming. Our farming trials and analyses help to optimise fertilisation using peat-reduced substrates.
Peat substitutes: Switzerland imports about half a million cubic meters of peat every year. It is hoped that this will be reduced by finding less problematic substitutes, and ecological studies are underway to determine the viability of these substitutes. In cultivation trials, we test the suitability of these substitutes for use in plant production.

In cooperation with the company Insolight, the two research groups Renewable Energies and Horticulture have set up an agrovoltaic trial. Over the next few months, lamb’s lettuce will be grown both under the modules with dynamically adjustable light transmission and on a control plot. Its growth will be investigated and compared between the two cultivation methods.
