The project will seamlessly follow long-term experiments and monitoring at monitoring points. As part of the experiments, the effect of growing species-rich intercrops, soil treatment technology, intercropping, application of biochar, compost and composted biochar in combination with different doses of nitrogen fertilization will be evaluated. As part of these experiments, the accumulation of total organic carbon (Cox) in the soil will be monitored together with the evaluation of the stable fraction of carbon bound to mineral parts and light, easily decomposable carbon. During the vegetation period, soil respiration (CO2 emissions) and nitrous oxide and methane emissions will be measured regularly.
Documents will be compiled for the evaluation of the spatial variability of the potential for long-term carbon storage in soils within the Czech Republic. Furthermore, the MEMS model will be implemented into growth models that enable the modeling of organic carbon content, and their validation and selection of the most suitable model for MEMS implementation (HERMES, MONICA models) will take place. It will also be followed by the collection of literary sources focused on nitrous oxide and methane emissions, which will be supplemented with data obtained from experiments, especially from the point of view of the influence of nitrogen fertilization, soil compaction and the influence of weather conditions (rainfall and temperature), and based on these sources, an expert will be developed a tool enabling farmers to optimize the farming system so that emissions of these gases are reduced. The expert system will also include a methodology for optimizing nitrogen nutrition with an evaluation of the nitrogen nutrition index based on satellite images of spectral reflectance. The collection of data for the evaluation of the economic efficiency of the procedures included in the carbon management system will be ongoing, in particular the evaluation of the increased costs of seeds for the cultivation of species-rich intercrops and for the calculation of the costs of no-till establishment of stands, production and transport costs for the production of biochar, composted biochar and compost, costs for the production of compost extracts, etc. Verification of new procedures for composting and production of compost extracts will take place, and experiments with the products of new composting methods will be established in laboratory and field experiments. Indirect methods of evaluating the quantity and stability of stored carbon in the soil will be developed, using samples from experiments as well as from enterprises in which certain carbon farming practices are used.
