hey Roasty, indeed, I inoculate with my compost, and am also thinking of adding biology via plant material I bring from walks out in (hopefully not all too damaged) nature more, since my composts aren't quite what I need them to be yet. Ever since I began learning to assess the biology with a microscope, I have lost the ability to count on a compost to be what I need it to be - I must look the stark truth in the face
and learn to make my own haha
You need to be aware that EM does not bring you the soil food web, it is an inoculum of facultative bacteria.
What does that mean.
Facultative means they can live in aerobic
and anaerobic conditions. So they walk the line between survivable and non-survivable conditions for plants.
In anaerobic conditions, the wrong (wrong for our purposes, not inherently evil or anything like that haha) set of microbes is active, making enzymes and substances that are harmful to the plant, volatilizing nutrients, and thus disrupting nutrient cycling. Aerobes have little chance of thriving under the low-oxygen conditions this set of microbes promotes, so they will not be successful at nature's strategies of displacement and outcompetiton. Just adding compost, oftentimes will not suffice to turn things around in such situations.
It is here, and only here, at this single point along the sweeping scale of succession, that facultatives have their moment of stardom.
Out in the wild, that would be in highly compacted soils, growing mainly opportunistic weeds with any higher-successional plants weak and sickly, so nigh to barren landscapes.
They come into the anaerobic conditions and flourish, and with their activity start displacing the extreme anaerobes, shifting conditions more and more, until the aerobic community can take hold and in turn evolve.
Then, as the truly beneficial microbial community takes over, aerobic microfauna starts cycling nutrients in the way plants need them, and the facultatives will fade into the background, and only reappear in tiny pockets of the soil where needed.
So if your soils are in such dire conditions, EM inoculation will benefit you, assisting in the transition to better conditions.
But you still will need to introduce beneficial soil life in the form of
complete communities:
- with diverse microflora -
bacterial and fungal populations in the proportions suited to the successional needs of the crops you want to grow, mining the nutrients from mineral and organic matter in the soil and storing them in their bodies. Building microaggregation with their glues, strung together into airy, water retaining structures by fungal strands and thus continually improving conditions.
- And with a good diverse microfauna -
flagellates, amoebae, bacterial, fungal, and predatory nematodes - that will eat the bacteria and fungi and release excess nutrients into soil in perfect microamounts and forms the plant can take up.
It takes all of these groups for the real magic of living soil with all its perks to happen.
But even on the way there, benefits will start to show. The soils I have my plants in for example. I check them regularly via microscope so I know the ecosystem is fragile, and too bacterial. And yet, I also know the conditions to be fully aerobic, and in the process of shifting, if slowly, in the right direction - and my plants are already rather healthy even in this suboptimal-but-improving setting. It just gets better as it evolves further
All that said, I hope it makes sense to you when I say EM probably isn't going to do for you what you are hoping..
But who knows, maybe your soil is pretty dead after all?
If you do use EM, make sure to follow it up with some good compost - I think I've already ranted about good compost and how we can go recognize quality without a microscope, at least in general terms that can prevent us from acquiring compost that will introduce disease-causers and worsen things, somewhere in this thread. It's still a bit of a game of roulette, but it's worth playing
Because that's what's ultimately going to bring you the set of microbes needed for those lovely carefree healthy-plant-growing terpene-heaven-bringing no-tills!
Cheers!
