t st tantra Posted May 24, 2002 ive searched the site,theres not much here,not enough for a basic understanding anyway. these are rhizobium? are they in the soil and in the nodes? how does a new plant get some? is revs method of blenderizing nodes the best innoculation method? has anyone experimented in anyway? so many legumes die young can we do anything? t s t .

Auxin Posted May 24, 2002 When rhizobium bacteria form a node they are changed to rhizobia bacterioids, and can not be changed back to rhizobium. That means blenderizing nodes will not make a good innoculant because it takes an active rhizobium bacterium to make a new node (also it would promote rotting). Rhizobium are supposed to be ubiquitous in soil, so I would try making an inoculant by mixing numerous soil samples with water, decanting, and use that to water the seedlings. Thats my theory anyway, I have never tested it- but maby now I should. Share this post Link to post Share on other sites
squiresk Posted May 24, 2002 If you are gonna start producing soil microbe cultures you'd better watch out. There are some really nasty bugs out there. The bacilli and clostridia etc.. Some answers from my Micro book. """are they in the soil and in the nodes?""" Yep. Increasing populations near the plant roots due to the release of organic material. This is called the Rhizosphere. More fertile have a less pronounced RhizoSp. Less fertile have a more pronounced RhSp. Eg.. In RhiSp soil Unicellular bacteria = 1,200 X 10 (6) <<< ie times 10 to the 6 Fungi 12 x 10 (5) Protozoa 24 X 10 (2) but in control soil Unicellular bacteria 53 x 10 (6) Fungi 1 x 10 (5) Proto. 10 X 10 (2) """"how does a new plant get some?"""" ahhh.. Rhizobium infects and nodulates specific hosts. 1st. Free living Rhizo. Legum. farts about in the soil. 2nd. The plant root releases flavinoids. 3rd. The flavinoids stimulate the R.Leg. to produce NOD metabolites. 4th. NOD factor stimulates root hair to curl. ( kinda like Velcro. ) 5th, slowly penetrates to the root hairs nucleus. 6th. These bacteria change morpholgy and turn into nitrogen fixing folk. divide and replicate and you got youself a nodule. I gather they are very specific. """is revs method of blenderizing nodes the best innoculation method""" dunno,but I guess, pointless. FInd yourself whatever you wanna grow. eg clover. Put some in crappy soil. Dig up after 6 months, and wash the soil off the roots. Keep this as inoculum. Or you could just let nature take its course. "has anyone experimented in anyway? "" Not me. """so many legumes die young can we do anything? """ stop eating them. Share this post Link to post Share on other sites
