That appears to be a limited meta-analysis that itself postulated the reason temperate yield didn't improve because temperate soils were more fertilized on average than the tropical soil studies.
We're talking in the context of soil depletion in this thread, so I don't think their limited conclusion applies.
- Nasrudith 7y agoOne thing not mentioned often about rainforrests is that their soil is actually pretty damn terrible. Which is also why you see things like carnivorous plants there.
- jelliclesfarm 7y agoSo what if rainforest soil is terrible...their main function is to sequester carbon and act as a carbon sink supporting habitat and balance terrestrial ecology.
- Nasrudith 7y agoThat is more for "why it helps there in the first place" than any disparagement of the rainforests. That the soil is terrible is more reason to leave them there - especially when they provide steady rain. It isn't like temperate climates where you can rotate between farms, fields, and forrests over time easier.
- jelliclesfarm 7y agoright. i hear you. may i ask what you mean by 'terrible'...nutritionally deficient or acidic..etc etc?
- jelliclesfarm 7y agoPossibly. I haven’t done any studies. I find good soil management with rotation and maintaining soil biome is sufficient in my Ca 8a/8b soil. My fields have soils that can be categorized as yolo loam and adobe can’t.
