\n\t\t\t\tThe Ov Active Principle : at the heart of a differentiated agronomic offering<\/strong><\/strong>\t\t\t<\/p>\n\t\t\t<\/div>\n<\/div>\n\n\n

\n\t\n\n

A unique biofermentation for living soils and nourished crops
<\/h2>\n\n\n\n

OvinAlp Haute Fertilisation revolutionises soil health and plant nutrition thanks to the Ov active principle. This active ingredient comes from a unique process of slow solid biofermentation lasting 12 months. This process combines sheep manure and almost exclusively local plant materials. It notably includes grape pomace and olive pulp. A true concentrate of microbial biodiversity, the Ov active principle brings together more than 600 beneficial micro-organisms. These bacteria and fungi have been characterised by the French National Museum of Natural History.<\/p>\n\n\n\n

Benefits of the Ov active principle :<\/p>\n\n\n\n

\n\t\n\n
  • \n\t
    \n\t<\/div>\n\t\n\t\t\t
    \n\t\t\tStimulates soil life through the introduction of a wide diversity of beneficial micro-organisms\t\t<\/div>\n\t<\/li>\n\n\n
  • \n\t
    \n\t<\/div>\n\t\n\t\t\t
    \n\t\t\tSupplies humus to soils thanks to its high humic restitution rate\t\t<\/div>\n\t<\/li>\n<\/div>\n\n\n
    \n\t\n\n
  • \n\t
    \n\t<\/div>\n\t\n\t\t\t
    \n\t\t\tImproves soil structure, making soils more aerated and better able to retain water (humus can retain up to 20 times its weight in water)\t\t<\/div>\n\t<\/li>\n\n\n
  • \n\t
    \n\t<\/div>\n\t\n\t\t\t
    \n\t\t\tIncreases resistance and resilience of soils that have undergone disturbances (weather events, droughts, diseases, pollution)\t\t<\/div>\n\t<\/li>\n<\/div>\n\t<\/div>\n\t

    Optimisation<\/strong><\/strong><\/h2>\n\n\n\n

    The supply of fertilising units is essential to ensure crop productivity. However, the introduction of a large number of living micro-organisms is crucial to improve soil functioning and limit nutrient leaching.<\/p>\n\n\n\n

    Applying the Ov active principle to the soil means optimising the assimilation of primary (N, P, K) and secondary (Mg, Ca, Fe\u2026) mineral elements, as micro-organisms work to make them more available to plants.<\/p>\n<\/div>\n\n\n\n

    \n

    Resistance<\/strong><\/h2>\n\n\n\n

    A living soil is a soil whose vital functions are ensured by a large number of organisms. In the event of disturbance, even with a population decrease, the soil will continue to function.<\/p>\n<\/div>\n\n\n\n

    \n

    Resilience<\/strong><\/h2>\n\n\n\n

    After a disturbance, the remaining micro-organisms will survive better and repopulate the soil more rapidly.<\/p>\n<\/div>\n<\/div>\n\n\n\n

      The process complies with European regulations R(EC) 1069\/2009 and (EU) 142\/2011, guaranteeing optimal sanitary safety, with no weed seeds or pathogens.<\/p>\n\n\n\n

      A lever for agroecological and climate transition<\/strong><\/h2>\n\n\n\n

      With 300 kg of carbon equivalent sequestered per tonne applied, the Ov active principle actively contributes to the \u201c4 per 1000\u201d initiative, which promotes increasing carbon stocks in agricultural soils.<\/p>\n\n\n\n

      It is also one of the richest soil amendments in stable organic matter, ahead of horse manure composts, green waste composts, household waste composts and slurries.<\/p>\n\n\n\n

      According to a study conducted between 2021 and 2024 by the OvinAlp R&I Department (GHG balance):<\/p>\n\n\n\n

        \n
      • 6<\/strong>00 kg CO\u2082e stored\/ha for 1 tonne of product<\/li>\n\n\n\n
      • 196 kg CO\u2082e emitted (production, transport, application) \u2192 Net gain: +404 kg CO\u2082e\/ha<\/li>\n<\/ul>\n\n\n\n

        The Ov Active Principle therefore acts as a measurable and effective climate resilience tool.<\/p>\n\n\n\n

        Improved water retention for living soils<\/strong><\/h2>\n\n\n\n

        By restoring the three essential forms of soil organic matter, the Ov active principle significantly improves soil structure and porosity. The result is better water infiltration, increased retention capacity and a marked reduction in water stress. Users observe longer moisture retention after rainfall and reduced irrigation needs.
