If you would use an organic, non fertilised soil with enzymes being given throughout an 8-10 week cycle and a top dressing of worm compost given each second cycle, how often would you change the soil? I.e.: how many cycles would you run with the same soil and why?

salut. c'est toujours sujet a discussion mais le principe est bon .
Dans un système organique avec des enzymes et du lombricompost, on ne considère plus la terre comme un simple support jetable, mais comme un écosystème. Tant que la structure physique du sol ne s'effondre pas, tu peux faire des dizaines de cycles.
​1. Pourquoi ne pas changer le sol ?
​Le Réseau Trophique du Sol : Plus le sol est vieux, plus les colonies de bactéries et de champignons bénéfiques (mycorhizes) sont stables et efficaces. En changeant la terre, tu repars à zéro et tu perds ce "système immunitaire" naturel.
​Les Enzymes : En en donnant tout au long du cycle, tu aides à décomposer les racines mortes du cycle précédent pour les transformer en nutriments. Cela évite que le sol ne s'étouffe.
​2. La stratégie de régénération (Le point clé)
​Le sol ne s'use pas, il se vide de ses nutriments. Voici comment je gérerais les cycles :
​Apport de lombricompost : Ton top-dressing tous les deux cycles est une bonne base, mais pour du long terme, j'en ajouterais un peu entre chaque cycle.
​Amendements minéraux : Après 3 ou 4 cycles, le sol peut manquer de minéraux trace. Un peu de basalte, de poussière de roche ou de chaux dolomitique permet de maintenir le pH et la structure minérale.
​Le "No-Till" : L'idéal est de ne même pas retourner la terre. Tu coupes la plante à la base, tu laisses les racines dans le pot, et tu replantes juste à côté. Les enzymes feront le reste.
​3. Quand faut-il vraiment changer ?
​Il n'y a que deux raisons valables pour jeter ton sol :
​Accumulation de sels : Si tu as utilisé des engrais minéraux par erreur, le sol devient toxique.
​Infestation massive : Si tu as des ravageurs de racines (comme les pucerons de racine) qui reviennent à chaque cycle.
​Mon analyse : Si tu respectes ton programme (enzymes + lombricompost), tu peux facilement tenir 3 à 5 ans (soit 10-15 cycles) sans changer de terreau. La seule chose que tu feras, c'est rajouter un peu de matière organique au sommet pour compenser ce que la plante a mangé.
j'espère que la réponse n'est pas trop longue. bonne journée

until it cannot be remediated without more effort than it is worth, really...biggest issue would be hydrophobic properties
as long as you are doing trad stuff to tend to the web every 2/3 weeks, you can go a really long time. not sure exactly what a nonfertilized soil is but there are plenty of examples of 10/20 year old living web beds outdoors. size def helps with longevity and regenerative capabilties too

decomposition of roots in soil and ph swing - ask this fraze of google or any other search engine or AI .....
Theory and practice are two different things.
If you do for fun, no need of results - play up, try everything, i went through years of trials and errors, but now i understand processes and know how to maximize harvest.
In my personal view, thats biggest thread.

This is not really living soil but with living soil 5 years if done correctly. When done correctly you can feed th soil with compost tea and preferably some clovers or other small plants growing on surface to keep the soil living. And you want to add some nutrients like kelp, seaweed, worm casting, chicken shit, bat shit once in a while and some molasses to feed the bacteria. Also give additional fertilizer and nutrients in between grows. I dont know why the other grower complains about roots because with living soil you can just let them sit. If you are interested just do some research it is not that hard to archive but it is also not just add worm casting and done... Have fun growing! đź’š

Once. You just cant get rid of roots fast, you can't enrich soil back to good npk levels without composting.
I did runs with 0 feeding during life cycle, plants developed way worse, had 30% smaller harvest too ...
One of many attempts :

When growing in pots, once................new plants = new soil.
The build up of pathogens, pests and salts is a real issue that can not be avoided.
The soil is the basis for success, so why run the risk of an entire grow failing by trying to save a few dollars by re-using depleted soil?
The cost and effort involved with replenishing depleted soil into something usable again, is just as expensive as new soil, so why bother??
Over the last 30+ years of growing exclusively "organically", I have proven to myself that re-using soil in pots is bad practice.
