inbruma: Living Compost from Fire-Resilient Landscapes

INBRUMA: inside the morning fog

'Bruma' is the landscape manifestation of its health: a low fog, emanating directly from the forest and pastures, signaling thriving ecosystems from the soil up.

    research and methodology

    Scientific basis, field tests, and constraints that shaped the INBRUMA formulations

    Our research focuses on how to process local biomass without harming the landscape and with minimal energy use. Space on the farm, machinery footprint, and the overall impact on soil and surrounding ecosystems were central considerations. We are planning a solar power system to reduce fossil fuel dependence and evaluating a small bio-gas solution for future cycles.


    The formulation of INBRUMA draws from several sources:


    • studies on the biostimulant and allelopathic properties of Inula viscosa 
    • research on fungal activity and pH normalization in Cistus species 
    • ancient and modern composting practices 
    • scientific literature on the safe reuse of olive and vine prunings 
    • methods for creating acidic and microbially active substrates 
    • work on mycorrhizal inoculation for Mediterranean soils
       

    Biomass for landscape healing

    INBRUMA helps reverse erosion, replaces open-air burning, and lowers wildfire risk. In our area, between 70 and 85 percent of fires originate from agricultural burning or rural land management. By converting prunings into living substrate, we keep biomass in the ecosystem, strengthen soil carbon sinks, and improve water retention at a landscape scale. 

    Nature alliance

    This work is connected to broader collaborations and value/monitoring systems:


    1. European project ECHO Soil project for baseline soil analysis;
    2. Open Forest Protocol for carbon storage monitoring through time;
    3. ATA Trasubbie e Trasubbino protecting the surrounding valleys;
    4. Rights of Nature principles.


    All of these elements contribute to a land management model based on ecological function, transparency, and responsibility toward the landscapes we depend on.

    INBRUMA at a glance

    1. Material Origin

    3. Fungal Inoculation

    1. Material Origin

    The base is made of Inula viscosa, Cistus, olive and vine prunings. These are common in fire-prone landscapes, often burned or abandoned. Instead of fire, we use composting to return their value into the soil.

    2. Composition

    3. Fungal Inoculation

    1. Material Origin

    INBRUMA is made from 80 percent Inula and 20 percent Cistus. INBRUMA DeVigna is 50 percent INBRUMA and 50 percent olive and vine compost. Each is tested for balance of texture, pH, and compatibility with acidic or clayey soils. 

    3. Fungal Inoculation

    3. Fungal Inoculation

    4. Fire Risk and Soil Exposure

    Trichoderma strains are introduced during curing. Mycorrhizal fungi like Funneliformis mosseae are added just before application. The goal is to support early root colonisation and maintain microbial activity in degraded soils.

    4. Fire Risk and Soil Exposure

    4. Fire Risk and Soil Exposure

    4. Fire Risk and Soil Exposure

    Agricultural fires are the leading cause of wildfires in this area. By diverting prunings from burning and stabilising them in compost, we reduce fuel load and increase soil cover. This slows erosion and water loss.

    5. Replicability

    4. Fire Risk and Soil Exposure

    6. Expected Response

    The method is low input. Shredding, layering, passive aeration, and moisture control. It can be repeated with similar materials across other Mediterranean areas with minimal adjustment. 

    6. Expected Response

    4. Fire Risk and Soil Exposure

    6. Expected Response

    We apply the compost on soils with poor structure and low organic matter. First responses are improved infiltration, slower drying, and mycelial spread. Tested on: vegetables, herbs, fruit trees, salads, sawn herbs.
