  • 15. Biological Control Concept General Suppression Abundance & Diversity of soil micro- organisms promotes soil fertility and biological control; e.g., soil health (i.e.,biological control; e.g., soil health (i.e., compost extracts) Specific Suppression Specific microbes are antagonistic to plant pathogenic organisms; e.g., biofungicides (i.e., microbial inoculants)

  • 18. 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 plant disease organisms) • Increases the efficiency of delivered nutrients; can reduce fertilizer rate (e.g., MEND concept) • Not a “silver bullet”; still need minerals and SOM management for healthy crops
