Dr Elaine Inghams ‘Soil Food Web’ Lectures

Take a look at this amazing resource I’ve just discovered, it’s Dr Elaine Inghams lessons on the soil food web, as well as creating your own composts and compost teas/extracts. The information contained hereinafter is often behind a paywall.

“Elaine Ingham, Chief Scientist at Rhodale Institute came to Hawi, Hawai’i in July 2012 to deliver a 5 day seminar dedicated to studying, understanding, and improving our soil biology to assist in ecologically sound agricultural practices. This is where I got my introduction to the microscope and learned much of it’s importance. This was some of the best 30 hours of class ever, and I often re-watch this epic series to refresh myself and discover more as I tune my own magnification of understanding this microscopic wonderland.” – Drake of Natural Farming Hawaii.

This presentation consists of 18 videos containing a total of 26 hours of footage. For information purposes the audio quality is a little poor and the presentation slides are slightly out of focus.

Plant Growth-promoting Rhizobacteria Provide Greater Control Of Root-knot Nematodes

Suppression of the root-knot nematode [Meloidogyne incognita (Kofoid & White) Chitwood] on tomato by dual inoculation with arbuscular mycorrhizal fungi and plant growth-promoting rhizobacteria.

Arbuscular mycorrhizal (AM) fungi and plant growth-promoting rhizobacteria (PGPR) have potential for the biocontrol of soil-borne diseases. The objectives of this study were to quantify the interactions between AM fungi [Glomus versiforme (Karsten) Berch and Glomus mosseae (Nicol. & Gerd.) Gerdemann & Trappe] and PGPR [Bacillus polymyxa (Prazmowski) Mace and Bacillus sp.] during colonization of roots and rhizosphere of tomato (Lycopersicon esculentum Mill) plants (cultivar Jinguan), and to determine their combined effects on the root-knot nematode, Meloidogyne incognita, and on tomato growth. Three greenhouse experiments were conducted. PGPR increased colonization of roots by AM fungi, and AM fungi increased numbers of PGPR in the rhizosphere. Dual inoculations of AM fungi plus PGPR provided greater control of M. incognita and greater promotion of plant growth than single inoculations, and the best combination was G. mosseae plus Bacillus sp. The results indicate that specific AM fungi and PGPR can stimulate each other and that specific combinations of AM fungi and PGPR can interact to suppress M. incognita and disease development.
