The project was approved in 2017 within the Operational Groups (GO) to promote innovation in the national agricultural sector. It aims for a sustainable operation of the slurry fraction, acording to the EU2020 priorities for sustainable and intelligent growth. This project will be developed over the next four years.
The main objective is to disclose and demonstrate an innovative model, alternative to the traditional one, to minimize the problems of excess effluent livestock in the Dairy Farms (EPL), promoting their valuation as a supplier of organic matter to soils and availability of nutrients for production of biomass and its contribution to improving the economic sustainability of Livestock Intensive Dairy Cattle, valuing the biomass produced in soil decontamination and as an energy source for internal use of the units of exploration.
Go-Biochorume proposes to value the liquid fraction of manure as a fertilizer in plantations of fast-growing forest species (EFRC), by assessing their ability to extract nutrients from manure and their potential in soil remediation cultivation techniques. The use of EFRC reduces environmental impacts and its an added value for biomass production, which can be incorporated into farms as an energy source, contributing to the reduction of operating costs and better economic performance of EPL. Plants inoculated with mycorrhizal fungi of the selected species will be used to improve the physiological activity of the trees, namely the extraction of nutrients by plants, the production of biomass and resistance to diseases and pests.
Aspen and Pawlonia, due to their rapid growth and high biomass production, their high transpiration rate, their easy adaptation to the soil and climate, have been widely used as species for soil phytoremediation, making them fundamental for the results of this research.
It is expected with the implementation of these biological systems of EFRC and mycorrhizal fungi:
1. A significant contribution to the environment through the high absorption of nutrients, in particular nitrogen, avoiding the application of chemical fertilisers;
2. Production of biomass with high calorific value that can be used for internal consumption of the farm, reducing energy costs of the company, or for external consumption (diversification of products with economic dividend);
3. The production of nutrient-rich food for the farm’s own livestock (or for sale for external consumption) by reducing the company’s expenditure on feed purchases;
4. Reduction of the costs with the management, manipulation and transport of the companies with this type of effluents;
5. Significant contribution to the environment by capturing carbon dioxide from the atmosphere, integrating it into the global current of combating climate change.
