  • Beneficial Properties of Biochar

    Habitat for soil microorganisms (e.g.,Arbuscular Mycorrhizal fungi)

    Increased soil carbon

    Increased CEC (cation exchange capacity) Increased CEC (cation exchange capacity)

    Increased AEC (anion exchange capacity)

    Mimicking terra preta soil regeneration

  • Terra Preta soils, Amazonian Black Earth

    Transformed terra preta Nutrient-poor Oxisol in tropics

  • Soil Biology Principle

    The Number and Diversity of soil micro-organisms is both an indicator & a driverof soil fertiliy, biocontrol, and other soilfunctions.

    Soil Fertility, Disease Suppression,Soil Structure, Humus, Soil Moisture

  • Lower Bacterial Diversity Higher Bacterial Diversity

  • Biological Control Concept

    General Suppression

    Abundance & Diversity of soil micro-organisms promotes soil fertility andbiological control; e.g., soil health (i.e.,biological control; e.g., soil health (i.e.,compost extracts)

    Specific Suppression

    Specific microbes are antagonistic to plantpathogenic organisms; e.g., biofungicides(i.e., microbial inoculants)

  • Microbial Inoculants in Perspective

    Tool to manage soil biology, soil fertility,organic wastes, and create bio-fertilizers

    Can be used to manipulate the rhizosphere &phyllosphere (e.g., biological control of plantphyllosphere (e.g., biological control of plantdisease organisms)

    Increases the efficiency of deliverednutrients; can reduce fertilizer rate (e.g.,MEND concept)

    Not a silver bullet; still need minerals andSOM management for healthy crops
