In the HUMAX project, various measures for humus build-up in different combinations on arable land will be investigated. A unique feature of the HUMAX project is that these measures are to be applied in combination with agri-photovoltaic systems and agroforestry systems. The aim is to identify possible synergies of the measures and to show combined application options. The innovative potential of the HUMAX project lies in the fact that established measures of humus build-up (catch crops, winter greening, undersowing, compost application, etc.) are to be combined and tested with promising measures such as plant charcoal, amongst others. The combination with agroforestry systems opens up further potentials as a carbon sink, in addition to the humus build-up, since the trees and shrubs store carbon in above- and below-ground biomass and also bring with them a large substitution potential through the wood products and the material accumulating during the management of the woody plants. This will be precisely quantified in order to be able to make statements not only about the total carbon storage in the soil and the biomass, but also to be able to quantify the substitution effects and biomass potentials for plant carbon production through pyrolysis. By combining the various humus-building measures, ways will be found to maximize humus build-up and thus carbon sequestration, i.e., the soil's function as a carbon sink. Based on this, a modular system will be developed that allows farmers to put together the best possible combination of measures for targeted carbon and humus management and for energy generation by means of agri-photovoltaics on their farms.
