Please explain the method and application of effective microorganism in agriculture and general usage?

Question

is effective microorganism works?

Answer 1

An example of a generally used used and effective use of microorganism in agriculture adding nodulating bacteria to soybeans.

Nitrogen fixation is critical for high soybean yields. For nitrogen fixation to occur, the nitrogen-fixing bacteria known as Bradyrhizobia japonicum must be established in the soil through seed inoculation. Soybean can obtain up to 75% of its nitrogen requirements from the air when nitrogen-fixing bacteria have established functioning nodules on the roots.

Bradyrhizobia japonicum can be added as a liquid, a granular peat inoculant, or as a peat-based powder. The different forms can be seed-applied or used in-furrow. Inoculant is relatively inexpensive and can give good increases in yields as well as a cheap Nitrogen supply.

Answer 2

John H's answer is basically correct, except it is far more general than just soybeans.

Iin the same way that humans depend on mitochondria for life, an enormous number of plants depend on microorganisms to provide them with nutrients.

Nitrogen fixing is only one of the many relationships, but perhaps the most widely known. An enormous number of agricultural crops benefit from this relationship.

In Australia, some native plants depend on a similar relationship for adequate potsassim (?) as australian soils are poor in Na (I don't think it s phosporus).

Answer 3

There are a number of micro-organisms developed and used. Milky-spore is a great product to control grubs that feed on roots. There was another product under a number of trade names, none of which I can remember but will try to find. Essentially it was a disease control product that was itself a micro-organism in a spray. What it did in short was to cultivate the surface of the plant and in that way took up all the space that would have been colonized by disease fungi. It worked by populating the plant with a benign microbe before disease had a chance. And worked great in the greenhouse, but I never saw it in the field use.
