Now this is interesting:
“the rhizosphere priming effect was positively correlated with aboveground plant biomass, but surprisingly not with root biomass“
- Grow diverse aboveground biomass
- Chop and drop
- Mulcho profit!
In a meta-analysis of 31 studies, researches show that the rhizosphere enhances soil organic carbon mineralization by 59%[*].
That woody species are best, then grass, then crops.
[Me: *So long as it’s fed from the above ground biomass litter.]
Sounds like C:Nhoosing Your Mulch? Think of the Fungi to me, and photosynthesise as much as you can be!
Don’t forget plant and mulch diversity in this mix, as Plant litter diversity increases microbial abundance, fungal diversity, and carbon and nitrogen cycling.
Another interesting study today suggests that soil fungal community is mainly influenced by plant community composition, distance between communities, and rainfall.
So go diverse and you can’t really lose.
Diverse ecosystems in connected communities.
