Zandor....What about beneficial bacteria and airstones?
1. Beneficial Pseudomonads
1. a. Specific species of beneficial pseudomonads that should be present in any soil, compost or compost tea will be identified and enumerated.
2. b. If the beneficial species are lacking, we can tell you which inoculum to go buy.
3. c. Most plate count labs do not differentiate disease-causing pseudomonads from true beneficials. If you have high numbers of pseudomonads, other services canâ??t tell if they are beneficial species or disease species. Now you have a way to tell.
2. Beneficial Bacillus species
1. a. Specific species of beneficial spore-forming bacteria, typically Bacillus species, that should be present in disease-suppressive conditions, specific insect-pest bio-control species will be identified and enumerated.
2. b. Most plate count labs do not differentiate the beneficials from the neutral spore-forming bacteria, and thus you donâ??t know if a high number of spore formers is a good thing or not. Now you have a better source of specific information.
3. Nitrogen Fixers
1. a. Specific species of true nitrogen fixing bacterial species will be identified and enumerated.
2. b. Plate count labs cannot differentiate nitrogen-scavengers from true nitrogen fixers. People have been mis-lead about the presence of the right N-fixing bacteria being present in their soils, compost and compost teas. Get the real and accurate information! Do you need to inoculate your clover with Rhizobium? Or do you have plenty of free-living N-fixers that improve most crop yields 5-30%?
4. Actinomycetes or Actinobacteria
1. a. These bacteria are quite beneficial for plant species that require strongly bacterial-dominated soils, such as brassica, kale and cole crops.
2. b. Actinobacteria are NOT desirable around conifer roots, nor highly beneficial for most VAM plant species, since they often inhibit ectomycorrhizal and VAM species
