During an internship a few years ago, I had an assignment in which we had to design an experiment to address a practical problem in agriculture. My assigned area was "semi-arid," so I focused on the Sahel. I did a lit review and found that intercropping grains with certain trees and shrubs was often beneficial for various reasons (hydraulic redistribution, soil microbial communities in leaf litter, nutrients brought up from the soil and deposit via leaves on the ground, shade during dry season).

I recently remembered I wrote this paper, and it's just been sitting on a hard drive. In case it's useful to anyone, I've attached it here. I'm also cross-posting in other possibly relevant forums here on permies.

Thanks!

Hi!

Someone recently commented on a post by @Ben Tyler that the link to Permaculture News' article on Unadilla's dynamic accumulator research was broken. Here are some relevant links:

The spreadsheet with the dynamic accumulator data from Unadilla:
https://docs.google.com/spreadsheets/d/19S3wsjXU6VPzmbklZLVxKt6DCyZIPjCYw6zRrVg7M4Y/edit#gid=662104531

This gives some context and info about their own research to expand the database with new data: https://unadillacommunityfarm.org/dynamicaccumulators/

What their database is based off of (Dr. Duke’s work):
https://phytochem.nal.usda.gov/phytochem/search/list
https://data.nal.usda.gov/dataset/dr-dukes-phytochemical-and-ethnobotanical-databases
https://nal.usda.gov/legacy/afsic/james-duke

...

Also, I want to share a list of related terms or synonyms for "dynamic accumulators" that I found while doing a lit review for an internship paper on tree nutrient accumulation and the possibility of using tree leaves as fertilizer:

○ root foraging
○ scavenge nutrients
○ dynamic accumulator
○ hyperaccumulation
○ biogeochemical
○ deep rooting
○ nutrient pumping
○ deep capture
○ nutrient uptake
○ nutrient uplift
○ aggrading vegetation
○ bioaccumulator
○ accumulator species
○ phytoremediation
○ heavy metal reclamation
○ plant uplift and recycling
○ phytoaccumulator
○ phytomining
○ phytoextraction
○ elements translocation
○ accelerator plants
○ mineral accumulator
○ mineral miner

...

Small sample of some papers from that lit review of interest:

In case any regenerative growers might benefit from this - https://advancingecoag.com/land/fieldlark/?_kx=m1tfn61mK0LzFkoB06R5bqSuv2mQruttBWWAiYECT3c.WdjHWJ&accordion=3

It's just a large language model AI. I imagine that as new AI's are developed, it will become more helpful in the future.

I agree. There’s not an easy on-ramp for RMH.

@Josh Warfield, I've added you to the list! Sadly, this is a slooow process, and it'll probably be years before I can get any beans to you. There's a handful of people that have my original beans that are growing them out this year in the Southwest of the US. If they are successful, then maybe there's a chance I can eventually get you some beans to try!
