  1. Mycorrhizae www.mycorrhiza.com Don’t Treat Soil Like Dirt Presenter Wendy Jansen

  2. What is Mycorrhizae Both Fungus and Roots Root and Fungus Tissue Non woody structures 90% of all plants Outer fruiting bodies Symbiotic Relationship http://www.gribscov.dk

  3. Symbiotic association Mutual exchange • The plant provides the fungus with sources of carbon. • In return, the fungus provides the plant with elements and water www.anbg.gov.au/fungi/mycorrhiza.html

  4. www: ag.arizona.edu Ectomycorrhiaze and Endomycorrhizae 1.Ectotrophic mycorrhizal symbiosis: Fungal mycorrhizal mycelium densely grows around the absorbing roots. 2. Endotrophic mycorrhizal symbiosis: Mycorrhizal hyphae are able to colonise the cortical cells.

  5. www.anbg.gov.au/fungi/mycorrhiza.html Mycorrhizae at work 1 We have an achlorophyllous plant using a parasitic fungus as its source of carbon. 2 Mushrooms that have arisen from a mycorrhizal fungus. 3. Buried fruiting bodies of a mycorrhizal, truffle-like fungus 4 Growing in the shade but it is connected to two mature plants by a mycorrhizal mycelia. 5. The mycelium of mycorrhizae has formed corticioid fruiting bodies on fallen twigs and mosses

  6. Mycorrhizal benefits Effective rooting Improve soil structure Block out harmful pathogens Decrease drought stress Tolerance of extremes Improved transplant survival Supply nutrients and water to the plant www.mycorrhizas.info/roles.html#B1

  7. The mycorrhizae miracle Mycorrhizal diversity • Abilities to produce antibiotics that retard soil pathogens. • Protecting plants from drought. • Producing enzymes that facilitate mineral uptake such as phosphorous and iron. • Access organic forms of nitrogen. Bio-organics.com

  8. We treat soil like dirt Effects on our environment

  9. We need to nurture our living soil • “Studies have documented that in highly disturbed environments, plants have not formed mycorrhizal relationships even many years after planting.” Dr Mike Amaranthus www.y:appliedturf.com

  10. Natural undisturbed areas Amazon • Teeming with a wide variety of mycorrhizae • Reach tremendous productivity without fertilisers, pesticides and irrigation. Photo By Leslie Taylor

  11. What we can do? Soil Food Web • In depleted soils, the soil must be repopulated with mycorrhizae. • But how? www.supremegrowers.com

  12. Borrowing from natures template Soil inoculants that include various species of mycorrhizae are grown commercially and available for purchase. The inoculum can introduced to plants during nursery production or applied to the soil. Mycorrhizal fungus inoculation is not required if appropriate fungi are already present. Landscape inoculant Bio-organics.com

  13. Fertiliser dependant plants Microbes will look after plants Mycorrhizoshpere • The Fungi is not an ‘add on’ to a fertiliser routine. • Grower Objective is to cut back on fertilisers. www.mycorrhiza.eu/e/home-e

  14. www.soilfoodweb.com What makes a healthy soil food web? All the organisms that a plant requires are present and functioning. Nutrients in the soil are in the proper forms so the plant can absorb them. The correct ratio of fungi to bacteria is present ensuring soil pH and soil structure.

  15. Rhizosphere remediation Re – establish mycorrhizae in degraded Soil • Mulch mulchmulch • Apply compost • Plant green manures • Plant variety • No dig gardens • Use Biochar as a carrier medium • And more mulch www.eatlivegrowpaleo.com/2012/06/square-foot-gardening-mulching-and.html
