The  ENOCHAR Project evaluates the effects of the application to the soil of biochar or its mixtures with compost, in field conditions in the medium to long term (5-7 years).

The goal of ENOCHAR is to acquire knowledge to be transferred to farmers and operators in the vine and wine chain regarding:
• long-standing evidence about the effectiveness of the application of biochar in viticulture, with particular attention to Carbon Sink and Nutrients Recovery, to demonstrate the ability to close cycles in the vineyard;
• evidence, for the new soil improvers, of the reduction of nutrient leaching, to the mitigation of dry periods thanks to the greater water retention capacity, to the better workability of clayey soils thanks to the reduction of the bulk density of the soils;
• certifications, with internationally recognized tools such as LCA, Carbon Footprint and PEF, of the sustainability of the new matrices and of the agricultural practices tested in the field;
• specialized know-how about biochar production techniques, methods and doses of administration in the field, as well as methods and machinery for distribution;
• dissemination of the knowledge on biochar and the systematic analysis of quality production of biochar starting from the residues of vine cultivation and then, once treated, return them to the soil, as a soil improver enriched with the nutrients recovered in the industrial processes of the supply chain;
To achieve these objectives, ENOCHAR prepares the following activities:
• application of the matrices to a new vineyard (about 1 hectare) planted at the experimental station of the CRPV located in Tebano (Ra); the experimental design foresees the comparison between 5 treatments: non-amended control, biochar, 2 biochar and compost blends and 1 compost only treatments;
• evaluate the effect of conditioning on soil properties (eg water retention capacity, structure, workability, etc.) as well as on the response of plants (nutritional status, productivity and quality of wines);
• monitoring of biochar and compost transformation in the soil, decomposition and aging also by means of modeling software;
• laboratory experiments by means of column tests to verify the absorbent and nutrient retention capacities of soils amended with the different matrices;
• laboratory experiments to evaluate the processes that are triggered by the co-maturation phase of compost and biochar;
• development and organization of communication activities and dissemination of results (eg visits to the experimental field, scientific and popular publications).
