The action plan aims at a sustainable operationalisation of the net slurry fraction compatible with the EU2020 priorities for sustainable and smart growth. The integration of new technologies in the use of effluent from cattle farms will not only reduce their impact on the environment, but will also improve their competitive capacity.
This is expected with the implementation of these biological systems of EFRC and mycorrhizal fungi:
1. A significant contribution to the environment due to the high absorption of nutrients, namely nitrogen, avoiding the application of chemical fertilizers;
2. Production of biomass with high calorific value that can be used for internal consumption of the farm, reducing the energy costs of the company, or for external consumption (diversification of products with economic dividend);
3. The production of nutrient-rich feed for the farm’s own livestock (or for sale for external consumption) by reducing the company’s expenditure on feed purchases;
4. Reducing the costs of managing, handling and transporting companies with this type of effluent;
5. Significant contribution to the environment through the capture of carbon dioxide from the atmosphere, integrating them into the global current to combat climate change;
However, the potential beneficiaries of this action will be bovine companies that intend to value and optimize the use of a by-product of their activity that presents a high polluting potential. Companies from other livestock activities that have this type of effluent may integrate these biological systems adapted to the characteristics of their waste in their farms. The entities that manage livestock effluents (companies and municipalities) may diversify the forms of recovery and final destination of the slurry.
Forestry production companies may use this business niche to diversify their products and, in association, bioinocular companies may arise in order to meet the need to produce mycorrhizal fungi for application in these systems. Biomass plants may benefit from the increase in local biomass production, with the offer of a product with a very interesting calorific value, integrated in a sustainable system.
Agricultural companies, with an interest in intercropping annual cultures with EFRC, in order to exploit and take advantage of the advantages that this duality offers, both in terms of soil structure and composition, and in terms of creating a more favourable microclimate when the land is in slightly adverse conditions.
In dry seasons, Paulownia sp. can absorb water from the deeper underground layers, absorbing the leached nutrients, and humidify the air through perspiration, benefiting the microclimate. It is an exceptional tree for intercropping with other cultures, improving the microclimate of cultures and increasing yields considerably. Populus sp., due to its characteristics of rapid growth and high biomass production, its high rate of transpiration, its easy adaptation to soil and climate, has been a widely used species for soil phytoremediation, becoming essential for the results of this research.

The National Institute for Agrarian and Veterinarian Research I. P. (INIAV) is the State Laboratory of the Ministry of Agriculture, Forests and Rural Development, that develops research activities in the agricultural and veterinary fields. It has the task of carrying out scientific and policy research to support public policies, while defending the national interests and the deepening of Europe’s common policies. [more]
